Molecular-clinical spectrum of the ATR-X syndrome

Abstract
Since the identification of the ATRX gene (synonyms XNP, XH2) in 1995, it has been shown to be the disease gene for numerous forms of syndromal X‐linked mental retardation [X‐linked α thalassemia/mental retardation (ATR‐X) syndrome, Carpenter syndrome, Juberg–Marsidi syndrome, Smith–Fineman–Myers syndrome, X‐linked mental retardation with spastic paraplegia]. An attempt is made in this article to review the clinical spectrum associated with ATRX mutations and to analyse the evidence for any genotype/phenotype correlation. Am. J. Med. Genet. (Semin. Med.
