What is Fragile X Syndrome?
Fragile X syndrome (FXS) is the most common inherited cause of autism and intellectual disabilities. It affects 1 in 4,000 boys and 1 in 6,000 girls worldwide.Fragile X syndrome occurs when a single gene on the X chromosome shuts down. This gene makes a protein needed for normal brain development. In FXS it does not work properly, the protein is not made, and the brain does not develop as it should.
Fragile X syndrome is a genetic disorder characterized by mild-to-moderate intellectual disability. The average IQ in males is under 55, while about two thirds of females are intellectually disabled. Physical features may include a Long and narrow face; High-arched palate; Large, protruding ears (both); Hyperextensible finger joints;Hyperextensible (‘double-jointed’) thumbs; Flat feet; Soft skin; Postpubescent macroorchidism (large testicles in men after puberty); and Hypotonia (low muscle tone).
