X-linked alpha-thalassemia/mental retardation syndrome (ATR-X) is a syndromic form of X-linked mental retardation. We investigated the X-inactivation status of nine female ATR-X carriers by methylation-specific PCR of the HUMARA gene. Six carriers demonstrated a skewed X-inactivation pattern (>90:10
A new X-linked recessive deafness syndrome was recently reported and mapped to Xq22 (Mohr-Tranebjaerg syndrome). In addition to deafness, the patients had visual impairment, dystonia, fractures, and mental deterioration. The female carriers did not have any significant manifestations of the syndrome
