Presentation on Fragile X syndrome www.AssignmentPoint.com

Fragile X syndrome Definition: Fragile X syndrome is the most common inherited form of mental retardation. It results from a change, or mutation, in a single gene, which can be passed from one generation to the next. Fragile X appears in families of every ethnic group and income level. www.AssignmentPoint.com

Causes, incidence, and risk factors: Fragile X syndrome is caused by a change in a gene called FMR1. A small part of the gene code is repeated on a fragile area of the X chromosome. The FMR1 gene makes a protein needed for brain to grow properly. A defect in the gene makes body produce too little of the protein, or none at all. Boys and girls can both be affected, but because boys have only one X chromosome, a single fragile X is likely to affect them more severely. A family history of fragile X syndrome, developmental problems, or intellectual disability may not be present. www.AssignmentPoint.com
