Fragile X syndrome
congenital disorder of nervous system / From Wikipedia, the free encyclopedia
Fragile X syndrome (FXS) is a genetic syndrome that causes a range of intellectual disabilities as well as unusual physical and behavioural characteristics. Males and females can have FXS but it is more common, and often more serious, in males.[1] It is one of the most common causes of autism and intellectual disability among boys.[2][3] Individuals with this condition lack an important gene product.[1]
