Methly-CpG-binding protein 2 (MECP2) mutations cause Rett syndrome in females. Here we report on a male infant with neonatal encephalopathy, myoclonic jerks, and irregular breathing patterns caused by a novel frameshift mutation in the MECP2 gene. In addition he has facial dysmorphisms previously not described in these patients.
