Fragile X Syndrome
Fragile X syndrome (FXS) is a genetic aberration that occurs primarily in males. Its symptoms include mild to moderate intellectual disability, a long and narrow face, large ears, flexible fingers, and large testicles. About 30% of those affected have features of autism such as problems with social interactions and delayed speech. Hyperactivity is commonly seen and seizures occur in about 10% of this population. Although there is no treatment for this problem, the symptoms can be managed with medication and therapy.
