A nonsense mutation of the ATRX gene causing mild mental retardation and epilepsy.

A nonsense mutation of the ATRX gene causing mild mental retardation and epilepsy.

Mutations in the X-encoded gene ATRX are known to give rise to profound syndromal mental retardation (MR). Here, we describe a pedigree, including 4 affected family members with a 324C-->T nonsense mutation in the ATRX gene. Although 2 patients have moderate to profound MR and the typical fac...

Description
Summary:Mutations in the X-encoded gene ATRX are known to give rise to profound syndromal mental retardation (MR). Here, we describe a pedigree, including 4 affected family members with a 324C-->T nonsense mutation in the ATRX gene. Although 2 patients have moderate to profound MR and the typical facial features of ATR-X syndrome, the other 2 patients presented with mild MR and epilepsy but without the characteristic facial dysmorphism. Mutations in the ATRX gene should be considered as a cause of mild MR in male patients lacking specific diagnostic features.
