Bradley Hospital in East Providence, boys have a mutation on the SLC9A6 gene on the X chromosome that disables production of a protein called NHE6 that is important for neurological developmenIn all CS cases, said Morrow who treats autism patients at the E.

Both findings suggest that different types of autism may share a common pathway even when they occur in distinct syndromes or alone — something that wasn't clear just from looking at the genes.

Scientists have identified the first gene that may contribute to autism, a type of mental retardation long thought to run in families.

Cook adds that the short form of the gene is only one factor in the disorder, as it occurs in 16 % of the general population, while less than 0.1 % is afflicted with autism.

Ed Cook, a psychiatrist at the University of Chicago Medical Center, reasoned that a gene that regulates serotonin levels might be involved in autism.
