+## 📊 Dataset Overview
+
+GenoTEX provides a benchmark for evaluating automated methods for gene expression data analysis, particularly for LLM-based agents. In biomedical research, gene expression analysis is crucial for understanding biological mechanisms and advancing clinical applications such as disease marker identification and personalized medicine. However, these analyses are often repetitive, labor-intensive, and prone to errors, leading to significant time and financial burdens on research teams.
+
+Key features of the benchmark include:
+
+- **1,384 NGS analysis problems**: 132 unconditional problems and 1,252 conditional problems
+- **41.5 GB of input data**: 911 datasets with an average of 167 samples per dataset (152,415 total samples)
+- **237,907 lines of analysis code**: Carefully curated by bioinformatics experts (average 261 lines per dataset)
+- **Three evaluation tasks**: Dataset selection, data preprocessing, and statistical analysis
+- **Comprehensive gene features**: Average of 18,530 normalized gene features per dataset
+- **Significant gene discoveries**: Significant genes identified per problem
+
+Each problem in the benchmark involves identifying genes associated with a specific trait (e.g., a disease) while optionally considering the influence of some condition (e.g., age, gender, or a co-existing trait). This approach mimics real-life research scenarios where key genes linked to traits often vary based on the diverse physical conditions of patients.
+
+<a id="dataset-structure"></a>
+## 🗂️ Dataset Structure
+
+GenoTEX is distributed in two ways:
+
+1. **Complete Datasets on Data Platforms**: We provide a complete, bundled version (code + data) on [Kaggle](https://www.kaggle.com/datasets/haoyangliu14/genotex-llm-agent-benchmark-for-genomic-analysis) and [Hugging Face Hub](https://huggingface.co/datasets/Liu-Hy/GenoTEX).
+These versions are convenient for users who prefer a single download and want to leverage the rich functionalities of these platforms. 
+2. **GitHub repository + Cloud storage**: In another version, we host the code and documentation in the [GitHub repository](https://github.com/Liu-Hy/GenoTEX), with links to the data in cloud storage. This version allows for efficient access to the analysis methods and their recent updates, while keeping the large data files separate.
+

+```
+
+### Notes on Data Organization:
+
+**1. Trait Name Normalization**: To make path operations safer, trait names are normalized by removing apostrophes (') and replacing spaces with underscores (_). For example, "Crohn's Disease" becomes "Crohns_Disease", and "Large B-cell Lymphoma" becomes "Large_B-cell_Lymphoma". This consistent formatting helps prevent path-related errors when working with the dataset.
+
+**2. Input Data Structure**:
+   
+   - **GEO folder**: Organized by our predefined trait names. Each trait directory holds 1-11 cohort datasets related to this trait, which were programmatically searched under specific criteria and downloaded from [the GEO database](https://www.ncbi.nlm.nih.gov/geo/) using [Entrez Utilities](https://www.ncbi.nlm.nih.gov/books/NBK25501/). Each cohort dataset is stored as a folder named after the GEO Series (GSE) number, such as 'GSE98578'. Each cohort folder contains `.gz` files, typically one SOFT file and one matrix file, though occasionally there are multiple SOFT files or matrix files.
+
+   - **TCGA folder**: Directly downloaded from [the TCGA Hub](https://xenabrowser.net/datapages/?host=https%3A%2F%2Ftcga.xenahubs.net&removeHub=https%3A%2F%2Fxena.treehouse.gi.ucsc.edu%3A443) of [the UCSC Xena platform](https://xena.ucsc.edu/), organized by different types of cancer. We preserve the original folder names from the website, without strictly matching our predefined trait names. Each trait (cancer) folder contains a clinicalMatrix file storing sample clinical features, and a PANCAN.gz file storing gene expression data.
+
+<a id="preprocessing-results-structure"></a>
+**3. Preprocessing Results Structure**:
+   
+   The 'output/preprocess/' folder is organized by predefined trait names. For each trait, it holds the clinical data, gene expression data, and the final linked data that are successfully preprocessed for each cohort into 3 separate CSV files. These CSV files are saved in '{trait_name}/clinical_data/', '{trait_name}/gene_data/', and '{trait_name}/' respectively, with the same filename '{cohort_ID}.csv'. 
+   For GEO cohorts, the cohort ID is the Series number (GSE); for TCGA, since there is at most one TCGA cohort related to each trait, we directly use 'Xena' as the cohort ID.
+
+   Additionally, each trait subfolder contains a JSON file, which stores metadata about dataset filtering and preprocessing outcomes of all related cohorts.
+
+#### Example Data Formats:
+   
+   **a. Gene Expression Data** (stored in `{trait_name}/gene_data/{cohort_ID}.csv`):
+   
+   This file contains gene expression values with gene symbols as rows and sample IDs as columns:
+   
+   ```
+            GSM7920782  GSM7920783  GSM7920784  ...  GSM7920825
+   A2M          13.210      13.238      14.729  ...       7.359
+   ACVR1C        5.128       5.337       5.611  ...       8.151
+   ADAM12        9.807      12.374       9.953  ...       9.266
+   ...             ...         ...         ...  ...         ...
+   ZEB2          9.534      10.488      10.553  ...       8.151
+   ```
+   
+   **b. Clinical Data** (stored in `{trait_name}/clinical_data/{cohort_ID}.csv`):
+   
+   This file contains clinical information with trait names as rows and sample IDs as columns:
+   
+   ```
+                 GSM7920782  GSM7920783  ...  GSM7920825
+   Breast_Cancer        1.0         1.0  ...         0.0
+   Age                 49.0        44.0  ...        74.0
+   Gender               0.0         0.0  ...         1.0
+   ```
+   
+   **c. Linked Dataset** (stored in `{trait_name}/{cohort_ID}.csv`):
+   
+   This file combines clinical and gene expression data with samples as rows and all features (clinical and gene) as columns:
+   
+   ```
+              Breast_Cancer    Age  Gender     A2M    ACVR1C    ADAM12  ...     ZEB2
+   GSM7920782           1.0   49.0     0.0  13.210     5.128     9.807   ...   9.534
+   GSM7920783           1.0   44.0     0.0  13.238     5.337    12.374   ...  10.488
+   ...                   ...   ...     ...     ...       ...       ...   ...     ...
+   GSM7920825           0.0   74.0     1.0   7.359     8.151     9.266   ...   8.151
+   ```
+   
+   **d. Cohort Information** (stored in `{trait_name}/cohort_info.json`):
+   
+This file contains outputs of dataset filtering (initial filtering and quality verification), and metadata about the preprocessing outcomes of each cohort related to the trait:
+   
+   ```json
+   {
+   "GSE207847": 
+     {"is_usable": true, "is_gene_available": true, "is_trait_available": true, "is_available": true, "is_biased": false, "has_age": false, "has_gender": false, "sample_size": 60},
+   "GSE153316":
+     {...},
+   ...
+   }
+   ```
+   
+   Each cohort entry contains the following fields:
+   - `is_gene_available` and `is_trait_available`: Indicate whether the dataset has the relevant gene expression and trait information, respectively. `is_available` is true if both are available.
+   - `is_biased`: Indicates whether the trait distribution is severely biased. For example, if a dataset about breast cancer treatment only contains positive samples, it would be considered biased and not usable for trait-gene association studies.
+   - `is_usable`: True if `is_available` is true and `is_biased` is false.
+   - `has_age` and `has_gender`: Indicate whether the dataset contains the samples' age and gender information, respectively.
+   - `sample_size`: Records the number of samples in the final linked dataset, after discarding samples with too many missing features.
+
+<a id="regression-results-structure"></a>
+**4. Regression Results Structure**:
+   
+   The 'output/regress/' folder is also organized by predefined trait names. It holds the regression analysis outputs for all NGS analysis problems in our benchmark that involve the same trait. These problems are uniquely identified by a trait-condition pair.
+   
+   The analysis output for each problem is stored in a file named "significant_genes_condition_{condition name}.json", where the condition name is either a predefined trait name, or 'Age', 'Gender', or 'None'. A 'None' condition represents an unconditional problem—"What are the significant genes related to this trait?"—without considering the influence of any conditions.
+   
+   Each JSON file contains:
+   
+   ```json
+   {
+       "significant_genes": {
+           "Variable": ["TRIB1", "MTMR14", "ANKFY1", ...],
+           "Coefficient": [-3.6007, 2.7751, -2.5880, ...],
+           "Absolute Coefficient": [3.6007, 2.7751, 2.5880, ...]
+       },
+       "cv_performance": {...}
+   }
+   ```
+   
+   - `significant_genes`: A dictionary with three keys:
+     - `Variable`: List of gene symbols identified as significant
+     - `Coefficient`: The corresponding coefficients in the trained regression model
+     - `Absolute Coefficient`: The absolute values of these coefficients
+   
+   The gene symbols are ranked by importance (absolute coefficient in Lasso models). The `cv_performance` part is used mainly for model validation and diagnostics, not part of our benchmark evaluation.
+
+**5. Metadata Structure**:
+   
+   - `task_info.json`: Contains full specifications for the NGS analysis problems in our benchmark, and domain knowledge about gene-trait associations. For each trait, it includes:
+   
+      ```json
+      {
+          "Acute_Myeloid_Leukemia": 
+          {
+              "related_genes": ["DNMT3A", "FLT3", "CEBPA", "TET2", "KIT", ... ],
+              "conditions": ["Age", "Gender", "Eczema", ... ]    
+          },
+          "Adrenocortical_Cancer": {
+              ...
+          }
+      }
+      ```
+   
+     - `related_genes`: A list of genes known to be associated with the trait, sourced from [the Open Targets Platform](https://platform.opentargets.org/downloads)
+     - `conditions`: The list of conditions paired with the trait to form the NGS analysis problems in our benchmark
+   
+   - `gene_synonym.json`: Stores the mapping from common acronyms of human gene symbols to their standard symbols, sourced from [the NCBI Gene FTP Site](https://ftp.ncbi.nlm.nih.gov/gene/DATA/). This is useful for normalizing gene symbols during preprocessing to prevent inaccuracies arising from different gene naming conventions. Standard symbols are mapped to themselves.
+   
+      ```json

+
+The code part of the benchmark includes:
+
+- **code/**: Contains our code for gene expression data analysis. The main part is the code for preprocessing each cohort dataset, organized by predefined trait names. We provide the code as Jupyter Notebook files with the name '{cohort_ID}.ipynb', showing the output of each step to facilitate interactive analysis. `regress.py` implements our regression analysis method in fixed logic, for solving the NGS analysis problems in our benchmark.
+
+- **tools/**: Contains the function tools that are accessible to both human bioinformaticians and LLM agents for gene expression data analysis.
+
+- **utils/**: Contains the helper functions used for this project outside of the data analysis tasks, e.g., experiment logging, evaluation metrics, etc.
+
+- **download/**: Contains the scripts for programmatically searching and downloading input gene expression datasets, and acquiring domain knowledge files from public repositories. It also includes the script for selecting important trait-condition pairs to form our NGS analysis problems.
+
+- **Documentation files**: `datasheet.md` provides the [Datasheets for Datasets](https://arxiv.org/abs/1803.09010) documentation of our benchmark, and `metadata.json` provides [the Croissant metadata](https://github.com/mlcommons/croissant) in [JSON-LD](https://json-ld.org/) format.

+## 📥 Installation
+
+1. Download this dataset from the data platform, and unzip the downloaded file.
+
+2. **For Kaggle Users Only**: Kaggle automatically unzips all `.gz` files, but our code requires certain files to remain compressed. Run the provided script to recompress these files (this will also save significant disk space):
+   ```bash
+   python recompress_files.py
+   ```
+
+3. Create and activate a conda environment:
+   ```bash
+   conda create -n genotex python=3.10
+   conda activate genotex
+   pip install -r requirements.txt
+   ```
+
+<a id="usage"></a>
+## 💻 Usage
+
+### Exploring the Benchmark
+
+The GenoTEX benchmark code is organized into two complementary components. First, you'll find Jupyter notebooks in the `./code/{trait_name}/` directories that handle dataset-specific preprocessing. These notebooks prepare individual datasets by cleaning, standardizing, and integrating the data, but they don't perform the actual association studies.
+
+The statistical analysis that identifies genes associated with traits is centralized in the `./code/regress.py` script. This script automatically selects the optimal cohort(s) from all preprocessed datasets for each problem, applies appropriate statistical models, and performs hyperparameter tuning to identify significant genes.
+
+This design separates data preparation from statistical modeling, enabling consistent methodology across all analyses while maximizing statistical power through automatic cohort selection. To run the complete pipeline, first execute the preprocessing notebooks for individual datasets, then run the regress.py script to perform association studies across all problems.
+
+### Evaluating Your Own Methods
+
+After developing your automated method for gene expression data analysis, you can evaluate it against our benchmark:
+
+1. Ensure your method produces output following the same format as our benchmark. Your output should be organized in the same structure as our `./output` directory, with:
+
+   - Preprocessed datasets and JSON files in the same folder structure and file format as described in [Preprocessing Results Structure](#preprocessing-results-structure)
+   - Regression results with gene lists ranked by importance, in the same JSON format as described in [Regression Results Structure](#regression-results-structure)
+
+2. Run the evaluation script:
+   ```bash
+   python eval.py -p {prediction_directory} -r {reference_directory} -t selection preprocessing analysis -s gene clinical linked
+   ```
+
+   Where:
+   - `-p`, `--pred-dir`: Path to the directory containing your prediction results, required.
+   - `-r`, `--ref-dir`: Path to the directory containing reference benchmark results (default: "./output")
+   - `-t`, `--tasks`: Specific tasks to evaluate: "selection" (dataset filtering and selection), "preprocessing" (data preprocessing), "analysis" (statistical analysis) - omit to evaluate all tasks
+   - `-s`, `--preprocess-subtasks`: Specific preprocessing aspects to evaluate: "gene" (expression data), "clinical" (trait data), "linked" (final linked data) - omit to evaluate all subtasks
+
+The evaluation produces metrics for each task:
+
+- **Dataset selection and filtering**: Evaluates the ability to identify useful datasets and select the optimal ones for analysis
+- **Data preprocessing**: Measures how well the method processes and integrates data from different sources
+- **Statistical analysis**: Assesses the accuracy of identifying significant genes related to traits
+
+The script will report errors arising from non-conformance in format, but you will need to correct any formatting issues to ensure accurate evaluation.

+      "!Series_summary\t\"The IL-23/IL-17 immune axis is of central importance in psoriasis. However, the contribution of IL-17 family cytokines other than IL-17A to drive skin inflammation in psoriasis has not been fully established. To further elucidate the role of individual IL-17 family cytokines in psoriasis, we investigated their expression and localization in psoriasis skin at the mRNA and protein level. Moreover, we investigated the gene expression signatures induced by individual IL-17 family cytokines in human skin ex vivo as well as modulation of responses induced by the combination of IL-17 family cytokines in human keratinocytes by brodalumab, a human monoclonal antibody targeting the IL-17RA, versus the IL-17A blocking antibody ixekizumab.     We demonstrate that IL-17A, IL-17AF, IL-17F and IL-17C are expressed at increased levels in psoriasis lesional skin and induce inflammatory gene expression signatures in human skin ex vivo that correlate with those observed in psoriasis. Furthermore, we show that brodalumab, in contrast to ixekizumab, fully blocks gene expression responses induced by the combination of IL-17A, IL-17AF, IL-17F and IL-17C in human keratinocytes.     These findings suggest that inhibition of several IL-17 family cytokines, e.g. by targeting of the IL-17RA receptor, could be a favored mechanism to obtain a profound suppression of the inflammatory processes in psoriasis and thereby achieve high levels of skin clearance and sustained efficacy in patients with psoriasis.\"\n",

+      "!Series_summary = The IL-23/IL-17 immune axis is of central importance in psoriasis. However, the contribution of IL-17 family cytokines other than IL-17A to drive skin inflammation in psoriasis has not been fully established. To further elucidate the role of individual IL-17 family cytokines in psoriasis, we investigated their expression and localization in psoriasis skin at the mRNA and protein level. Moreover, we investigated the gene expression signatures induced by individual IL-17 family cytokines in human skin ex vivo as well as modulation of responses induced by the combination of IL-17 family cytokines in human keratinocytes by brodalumab, a human monoclonal antibody targeting the IL-17RA, versus the IL-17A blocking antibody ixekizumab.     We demonstrate that IL-17A, IL-17AF, IL-17F and IL-17C are expressed at increased levels in psoriasis lesional skin and induce inflammatory gene expression signatures in human skin ex vivo that correlate with those observed in psoriasis. Furthermore, we show that brodalumab, in contrast to ixekizumab, fully blocks gene expression responses induced by the combination of IL-17A, IL-17AF, IL-17F and IL-17C in human keratinocytes.     These findings suggest that inhibition of several IL-17 family cytokines, e.g. by targeting of the IL-17RA receptor, could be a favored mechanism to obtain a profound suppression of the inflammatory processes in psoriasis and thereby achieve high levels of skin clearance and sustained efficacy in patients with psoriasis.\n",

+      "!Series_summary\t\"Phototherapy is an effective therapy and may induce remission of psoriasis.  Previous studies have established the action spectrum of clearance and that apoptosis is differentially induced in psoriasis plaques by clinically effective wavelengths of ultraviolet B (UVB).  The aim of this study was to investigate the molecular mechanisms regulating psoriasis plaque resolution by studying the transcriptomic response to clinically effective (311nm, narrow band) UVB compared to a clinically ineffective (290nm) wavelength.  We irradiated lesional psoriatic skin in vivo with a single 3 MED (minimal erythemal dose) of 311nm or 290nm wavelength of UVB and performed skin biopsies at 4h or 18h post irradiation and from un-irradiated lesional skin.  Forty-eight micro-dissected epidermal samples were analysed using the Illumina DASL array platform from 20 psoriatic patients.  Bioinformatic analysis identified differentially expressed genes (DEGs) associated with 311nm but not 290nm irradiation; these DEGs were subject to Ingenuity pathway and upstream regulator analysis.        The number of differentially regulated epidermal genes was greatest at 18h following UVB, after irradiation with clinically effective (311nm) UVB. The main pathways differentially affected by 311nm UVB only were apoptosis, necrosis, acute phase signalling, p53 signalling and chemotaxis. The greatest fold change observed was a 7.5 fold increase in expression of CDKN1A (WAF1/ p21), the p53 target gene, following irradiation with 311nm UVB but not 290nm (clinically ineffective UVB).  Acute phase, LXR and PTEN signalling, dendritic cell maturation, granulocyte adhesion and atherosclerotic pathways were also differentially regulated by 311nm compared to 290nm UVB.      This work provides insight into the molecular mechanisms regulating psoriatic remodelling in response to UV phototherapy, supports a key role for apoptosis and cell death in psoriasis plaque clearance, and identifies a number of novel therapeutic pathways.  Further studies may lead to development of potential biomarkers to assess which patients are more likely to respond to UVB.\"\n",

Previous studies have established the action spectrum of clearance and that apoptosis is differentially induced in psoriasis plaques by clinically effective wavelengths of ultraviolet B (UVB).  The aim of this study was to investigate the molecular mechanisms regulating psoriasis plaque resolution by studying the transcriptomic response to clinically effective (311nm, narrow band) UVB compared to a clinically ineffective (290nm) wavelength.  We irradiated lesional psoriatic skin in vivo with a single 3 MED (minimal erythemal dose) of 311nm or 290nm wavelength of UVB and performed skin biopsies at 4h or 18h post irradiation and from un-irradiated lesional skin.  Forty-eight micro-dissected epidermal samples were analysed using the Illumina DASL array platform from 20 psoriatic patients.  Bioinformatic analysis identified differentially expressed genes (DEGs) associated with 311nm but not 290nm irradiation; these DEGs were subject to Ingenuity pathway and upstream regulator analysis.        The number of differentially regulated epidermal genes was greatest at 18h following UVB, after irradiation with clinically effective (311nm) UVB. The main pathways differentially affected by 311nm UVB only were apoptosis, necrosis, acute phase signalling, p53 signalling and chemotaxis. The greatest fold change observed was a 7.5 fold increase in expression of CDKN1A (WAF1/ p21), the p53 target gene, following irradiation with 311nm UVB but not 290nm (clinically ineffective UVB).  Acute phase, LXR and PTEN signalling, dendritic cell maturation, granulocyte adhesion and atherosclerotic pathways were also differentially regulated by 311nm compared to 290nm UVB.      This work provides insight into the molecular mechanisms regulating psoriatic remodelling in response to UV phototherapy, supports a key role for apoptosis and cell death in psoriasis plaque clearance, and identifies a number of novel therapeutic pathways.  Further studies may lead to development of potential biomarkers to assess which patients are more likely to respond to UVB.\n",

We enrolled patients diagnosed with either psoriasis or atopic dermatitis, and clinically re-stratified them into classic psoriasis, classic atopic dermatitis, and the overlap phenotype between psoriasis and atopic dermatitis. We compared gene expression profiles of lesional and nonlesional skin biopsy tissues between the three comparison groups. Global mRNA expression and T-cell subset cytokine expression in the skin of the overlap phenotype were consistent with the profiles of psoriasis and different from the profiles of atopic dermatitis. Unsupervised k-means clustering indicated that the best number of distinct clusters for the total population of the three comparison groups was two, and the two clusters of psoriasis and atopic dermatitis were differentiated by gene expression. Our study suggests that clinical overlap phenotype between psoriasis and atopic dermatitis has dominant molecular features of psoriasis, and genomic biomarkers can differentiate psoriasis and atopic dermatitis at molecular levels in patients with a spectrum of psoriasis and atopic dermatitis. \"\n",

We enrolled patients diagnosed with either psoriasis or atopic dermatitis, and clinically re-stratified them into classic psoriasis, classic atopic dermatitis, and the overlap phenotype between psoriasis and atopic dermatitis. We compared gene expression profiles of lesional and nonlesional skin biopsy tissues between the three comparison groups. Global mRNA expression and T-cell subset cytokine expression in the skin of the overlap phenotype were consistent with the profiles of psoriasis and different from the profiles of atopic dermatitis. Unsupervised k-means clustering indicated that the best number of distinct clusters for the total population of the three comparison groups was two, and the two clusters of psoriasis and atopic dermatitis were differentiated by gene expression. Our study suggests that clinical overlap phenotype between psoriasis and atopic dermatitis has dominant molecular features of psoriasis, and genomic biomarkers can differentiate psoriasis and atopic dermatitis at molecular levels in patients with a spectrum of psoriasis and atopic dermatitis.\n",

Despite the efforts to predict treatment response using tumor-molecular features, as differentially expressed genes, no molecule has proved to be a strong biomarker. The tumor secretome analysis is a promising strategy for biomarkers identification, which can be assessed using transcriptomic data. Here, we performed transcriptomic-based secretome analysis to select potentially secreted proteins using an in silico approach. The tumor expression profile of 28 LARC biopsies carefully selected and collected before nCRT was compared with normal rectal tissues (NT). The expression profile showed no significant differences between cases with complete (pCR) and incomplete response to nCRT. Genes with increased expression (pCR = 106 and pIR = 357) were used for secretome analysis based on public databases (Vesiclepedia, Human Cancer Secretome Database and Plasma and Proteome Database). Seventeen potentially secreted candidates (pCR=1, pIR=13 and 3 in both groups) were further investigated in two independent datasets (TCGA and GSE68204) confirming their over-expression in LARC. The potential secreted biomarkers were also confirmed as associated with the nCRT response (GSE68204). These putative proteins are candidates to be assessed in liquid biopsies aiming a personalized treatment in LARC patients.\"\n",

This dataset comprises the transcriptomic profiling of 39 consecutive eligible LARC patients who underwent therapy at the Oncology Unit at Bonorino Udaondo Hospital (Buenos Aires, Argentina) from November 2015 to September 2018. This study was approved by the Udaondo Hospital Ethics Committee and the Instituto Leloir Institutional Review Board. All patients signed the approved Informed Consent.  All patients were assigned to standard pelvic long course radiotherapy (LCRT: 50.4 Gy in 28 fractions of three-dimensional conformal radiotherapy, 1.8 Gy per fraction, per day) with concurrent capecitabine (825 mg/m2/bid for 28 days), termed hereafter CRT. Patients with a high risk of systemic relapse (EMVI, high mesorectal node burden and LLND) underwent TNT, which comprises pre-treatment before the CRT with three cycles of CAPOX (130 mg/m² of oxaliplatin on day 1 and capecitabine 1000 mg/m²/bid, days 1-14 every 3 weeks). Two cycles of capecitabine monotherapy (850 mg/m²/bid, days 1-14 every 3 weeks) was then administered until response assessment for all patients. Together, TNT and CRT are referred to as nCRT. Response to nCRT was evaluated on the surgical specimen by the  pathological tumor regression (pTRG) score proposed by  the seventh edition manual of the American Joint Committee on Cancer (AJCC), except for cases where pTRG was unavailable due to complete clinical response or unresectability. pTRG=0-1 and complete clinical responders were considered good responders, while pTRG=2-3 and unresectable patients were considered poor responders.

+      "!Series_summary\t\"Breast tumors from BRCA1 germ line mutation carriers typically exhibit features of the basal-like molecular subtype. However, the specific genes recurrently mutated as a consequence of BRCA1 dysfunction have not been fully elucidated. In this study, we utilized gene expression profiling to molecularly subtype 577 breast tumors, including 73 breast tumors from BRCA1/2 mutation carriers. Focusing on the RB1 locus, we analyzed 33 BRCA1-mutated, 36 BRCA2-mutated and 48 non-BRCA1/2-mutated breast tumors using a custom-designed high-density oligomicroarray covering the RB1 gene. We found a strong association between the basal-like subtype and BRCA1-mutated breast tumors and the luminal B subtype and BRCA2-mutated breast tumors. RB1 was identified as a major target for genomic disruption in tumors arising in BRCA1 mutation carriers and in sporadic tumors with BRCA1 promoter-methylation, but rarely in other breast cancers. Homozygous deletions, intragenic breaks, or microdeletions were found in 33% of BRCA1-mutant tumors, 36% of BRCA1 promoter-methylated basal-like tumors, 13% of non-BRCA1 deficient basal-like tumors, and 3% of BRCA2-mutated tumors. In addition, RB1 was frequently inactivated by gross gene disruption in BRCA1-related hereditary breast cancer and BRCA1-methylated sporadic basal-like breast cancer, but rarely in BRCA2-hereditary breast cancer and non-BRCA1-deficient sporadic breast cancers. Together, our findings demonstrate the existence of genetic heterogeneity within the basal-like breast cancer subtype that is based upon BRCA1-status.\"\n",
