Genital abnormalities have been noted in several patients with the X-linked form of alpha-thalassemia and mental retardation syndrome (ATR-X). The initial clinical report of the condition documented a phenotypic female with 46,XY karyotype. To this we now add 2 further siblings with abnormalities of the external genitalia, manifesting as male pseudohermaphroditism.

Most interest in the gene encoding the alpha-thalassemia, mental retardation, X-linked protein (ATRX) has traditionally been focused on its role in brain development and globin regulation. However, mutations in the ATRX gene also cause varying degrees of gonadal and urogenital abnormalities. These range from small testes to ambiguous external genitalia in XY individuals. ATRX is of great interest because this very large protein is one of the least understood proteins involved in mammalian sexual development. Although the biochemical role of ATRX remains unknown, recent and emerging evidence implicates ATRX in chromatin remodeling. We review what is known about ATRX as a chromatin remodeling protein, and its role in mammalian sex differentiation.
