Fragile X syndrome causes

Fragile X syndrome is caused by a change to a FMR1 gene on the X-chromosome. This gene responsible for brain development and to function normally. If this gene is altered in any way, it cannot produce its FMR1 protein, which can result in Fragile X syndrome.

Fragile x Syndrome is a genetic disease which is caused by mutation in the Fragile x Mental Retardation 1(FMR1) gene in X chromosome. Generally, these mutation (>200 repeats of CGG) occurs at in the 5′ untranslated region of FMR1. In around 2% of cases, Fragile X syndrome can occur as a result of point mutation in FMR1 gene.
