摘要
Background: Among the well characterized X-linked conditions causing mental retardation, mutations in the methyl-CpG-binding protein 2 gene (MECP2) in Xq28 have been found in up to 85% of patients with Rett syndrome, a neurologic disorder which, in addition to other symptoms, severely affects higher cognitive functions in females. Mutations in the MECP2 gene are involved in a broad spectrum of phenotypes from classical Rett syndrome to mild intellectual difficulties in females and neonatal encephalopathy in males. Recently, mutations in the MECP2 gene were reported in males with non-specific mental retardation suggesting that defects in MECP2 could be responsible for up to 2% of X-linked mental retardation.
