Fragile X research

Researchers have new findings on fragile X, an autism-linked genetic disorder. Fragile X Syndrome (FXS) is an inherited cause of intellectual disability, especially among boys. It results in a spectrum of intellectual disabilities ranging from mild to severe, as well as physical characteristics, such as an elongated face, large or protruding ears, and large testes. Accompanying behavioral characteristics include stereotypic movements, such as hand-flapping, and social anxiety.
