More than 200 syndromic and nonsyndromic disorders associated with X-linked mental retardation are known, and the gene responsible for the condition has been identified in many cases. The phenotypic effects of known MRX genes, and their obvious overrepresentation on the X chromosome, suggest that they played an important role during human speciation.
