- The SNCA gene provides instructions for making a small protein called alpha-synuclein. Alpha-synuclein is abundant in the brain, and smaller amounts are found in the heart, muscles, and other tissues.everal common variations in the SNCA gene have been found to increase the risk of multiple system atrophy, a progressive brain disorder that affects movement and balance and disrupts the function of the autonomic nervous system.

- Saethre–Chotzen syndrome, also known as Acrocephalosyndactyly type III is a rare congenital disorder associated with craniosynostosis. This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face. Individuals with SCS also have droopy eyelids, widely spaced eyes, and minor birth defects of the hands and feet. In addition, individuals with more severe cases of SCS may have mild to moderate mental retardation or learning disabilities. Depending on the ...

ATN1 gene The ATN1 gene provides instructions for making a protein called atrophin 1. Although the exact function of this protein is unknown, it appears to play an important role in nerve cells (neurons) in many areas of the brain. Based on studies in other animals, researchers speculate that atrophin 1 may act as a transcriptional co-repressor. A transcriptional co-repressor is a protein that interacts with other DNA-binding proteins to suppress the activity of certain genes, although it cannot attach (bind) to DNA by itself. One region of the ATN1 gene contains a particular DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks (cytosine, adenine, and guanine) that appear multiple times in a row. In most people, the number of CAG repeats in the ATN1 gene ranges from 6 to 35.

Mutations in the p53 Tumor Suppressor Gene: Important Milestones at the Various Steps of Tumorigenesis Inactivation of the p53 tumor suppressor is a frequent event in tumorigenesis. In most cases, the p53 gene is mutated, giving rise to a stable mutant protein whose accumulation is regarded as a hallmark of cancer cells.Mutant p53 proteins not only lose their tumor suppressive activities but often gain additional oncogenic functions that endow cells with growth and survival advantages.verall, early mutations in the TP53 gene caused by various carcinogens are a typical example of the possible involvement of mutant p53 in tumor initiation and in early stages of tumor development.

Gene A. BRCA1 (breast cancer 1, early onset) is a human gene that belongs to a class of genes known as tumor suppressors, which maintains gene integrity to prevent uncontrolled proliferation (what causes cancer cells to develop).ariations in the gene have been implicated in a number of hereditary cancers, mainly breast, ovarian and prostate. The BRCA family of genes are known today to give a significant increased risk for breast cancer in families.

- Alpha-synuclein is a member of the synuclein family, which also includes beta-and gamma-synuclein. Synucleins are abundantly expressed in the brain and alpha-and beta-synuclein inhibit phospholipase D2 selectively. SNCA may serve to integrate presynaptic signaling and membrane trafficking.GI mutant phenotypes for SNCA: inferred from 6 alleles. 1  reproductive system phenotype. 2  skeleton phenotype. 3  mortality/aging. 4  endocrine/exocrine gland phenotype. 5  cellular phenotype. 6  cardiovascular system phenotype. 7  growth/size/body phenotype. 8  homeostasis/metabolism phenotype.

Alone we are rare. Together we are strong.â¥ Donate Today The symptoms of Glut1 deficiency syndrome result from abnormalities of glucose transport to the brain. Glucose is a simple sugar and is the main source of fuel for brain metabolism. The SLC2A1 gene contains instructions for creating (encoding) a protein known as glucose transporter type 1 (Glut1). Mutations of the SLC2A1 gene result in low levels of functional Glut1.

CSA-dependent degradation of CSB by the ubiquitinâproteasome pathway establishes a link between complementation factors of  the Cockayne syndrome Mutations in the CSA or CSB complementation genes cause the Cockayne syndrome, a severe genetic disorder that results in patients’ death in early adulthood. CSA and CSB act in a transcription-coupled repair (TCR) pathway, but their functional relationship is not understood. We have previously shown that CSA is a subunit of an E3 ubiquitin ligase complex. Here we demonstrate that CSB is a substrate of this ligase: Following UV irradiation, CSB is degraded at a late stage of the repair process in a proteasome- and CSA-dependent manner. Moreover, we demonstrate the importance of CSB degradation for post-TCR recovery of transcription and for the Cockayne syndrome.

Causes and origins of Tourette syndrome Tourette syndrome (also called Tourette's syndrome, Tourette's disorder, Gilles de la Tourette syndrome, GTS or TS) is an inherited neurological disorder with onset in childhood, characterized by the presence of multiple motor tics and at least one phonic tic, which characteristically wax and wane.n some cases, tics may not be inherited; these cases are identified as sporadic Tourette syndrome (also known as tourettism) because a genetic link is missing. A person with Tourette syndrome has about a 50% chance of passing the gene(s) to one of his/her children.

Overview Mayo Clinic in Minnesota has been recognized as the best Gastroenterology & GI Surgery hospital in the nation for 2015-2016 by U.S. News & World Report. Lynch syndrome is an inherited condition that increases your risk of colon cancer and other cancers. Lynch syndrome has historically been known as hereditary nonpolyposis colorectal cancer (HNPCC). A number of inherited syndromes can increase your risk of colon cancer, but Lynch syndrome is the most common. Doctors estimate that about 3 out of every 100 colon cancers are caused by Lynch syndrome. Families that have Lynch syndrome usually have more cases of colon cancer than would typically be expected.

- isolated Duane retraction syndrome. At least seven mutations in the CHN1 gene have been identified in families with isolated Duane retraction syndrome. Researchers believe that the features of this condition result from changes in one of the two versions of the CHN1 protein, α2-chimaerin. Each identified mutation changes a single protein building block (amino acid) in α2-chimaerin.
