Utah researchers: Chromosome may harbor autism gene

One gene, FXR1, appeared to be a likely candidate for a link to autism. FXR1 is similar to the X-chromosome Fragile X gene, FMR1. Mutations in FMR1 cause Fragile X Syndrome, an inherited condition that can cause mental impairments ranging from learning disabilities to severe cognitive problems. Fragile X syndrome has been shown to overlap with autism, and because FXR1 is similar to the gene that causes the syndrome, U researchers suspected FXR1 might be linked to autism. But after analyzing the entire coding sequence of FXR1, the researchers found no alterations in the gene likely to contribute to autism.
