- Klinefelter syndrome is a condition related to the X and Y chromosomes (the sex chromosomes). People typically have two sex chromosomes in each cell: females have two X chromosomes (46,XX), and males have one X and one Y chromosome (46,XY).

Klinefelter syndrome Most commonly, a male with Klinefelter syndrome will be born with 47 chromosomes in each cell, rather than the normal number of 46. The extra chromosome is an X chromosome. This means that rather than having the normal XY combination, the male has an XXY combination.

Klinefelter syndrome Klinefelter syndrome is a chromosomal condition that affects male physical and cognitive development. Its signs and symptoms vary among affected individuals. Affected individuals typically have small testes that do not produce as much testosterone as usual.

A Genetic Clotting Condition or Thrombophilia A Genetic Clotting Condition or Thrombophilia. Prothrombin 20210 Mutation, also called Factor II Mutation is a genetic condition that causes an increase in the likelihood of your blood forming dangerous blood clots. All individuals make the prothrombin (also called factor two) protein that helps blood clot. However, there are certain individuals who have a DNA mutation in the gene used to make prothrombin (also called prothrombin G20210A or the factor II (two) mutation).

Mutation Spectra in Fragile X Syndrome Induced by Deletions of CGGÂ·CCG Repeats * Hence, the phenomenon of gross deletions of the FMR1 gene causing the fragile X syndrome is not an isolated event. Point Mutations —To this point, the previously described types of mutations are believed to be promoted by the presence of long CGG·CCG repeats.

How Gene Mutation Works Altering nucleotide sequences most often results in nonfunctioning proteins. Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions.Point mutations are the most common type of gene mutation. Also called a base-pair substitution, this type of mutation changes a single nucleotide base pair.ltering nucleotide sequences most often results in nonfunctioning proteins.

Klinefelter syndrome Klinefelter Syndrome is a chromosome abnormality that affects only boys/men. People with Klinefelter are born with at least one extra X chromosome. The male with Klinefelter will be born with 47 chromosomes in each cell, rather than the normal number of 46. Klinefelter Syndrome is also called 47, XXY syndrome.

Klinefelterâs syndrome The extra X chromosome may come from the egg or sperm, or be ‘added’ early in the development of the embryo. In either case it is not known why the extra X chromosome happens. The brothers of men with Klinefelter’s syndrome almost always have a normal 46, XY chromosome pattern.

What Is Klinefelter Syndrome? Definition. Klinefelter syndrome is a genetic condition that results when a boy is born with an extra copy of the X chromosome. Klinefelter syndrome is a common genetic condition affecting males. Klinefelter syndrome adversely affects testicular growth, and this can result in smaller than normal testicles.

Glossary: what does this word mean? Klinefelter Syndrome. What is Klinefelter syndrome? Klinefelter syndrome is a group of conditions that affects the health of males who are born with at least one extra X chromosome. Chromosomes, found in all body cells, contain genes. Genes provide specific instructions for body characteristics and functions. For example, some genes determine height and hair color.

- Most children with Rett syndrome have a mutation in a particular gene on the X chromosome. Exactly what this gene does, or how its mutation leads to Rett syndrome, isn't clear. It's believed that the single gene may influence many other genes involved in development.hen boys develop the Rett syndrome mutation, they die shortly after birth. Because boys have only one X chromosome (instead of the two girls have), the disease is more serious, and quickly fatal.
