摘要

BACKGROUND: Rett syndrome is a neurodevelopmental disorder that occurs in individuals with a mutation in the X-linked methyl-CpG-binding protein 2 (2MECP2) gene. 2MECP2 mutations produce a high degree of variability in the clinical phenotypes including the classic Rett features of head growth deceleration, psychomotor regression, deviant communicative ability, hand stereotypes, autonomic dysfunction, and seizures. Atypical forms of Rett such as those with preserved speech do not follow these characteristics. PATIENT: We report a 9-year-old girl with atypical Rett (macrocephaly, preserved speech, and psychiatric manifestations) with a 2MECP2 (P152R) mutation that generally is not associated with these clinical signs. CONCLUSION: This case broadens the genotype-phenotype correlation between the P152R mutation 2MECP2-associated Rett syndrome. (C) 2013 Elsevier Inc. All rights reserved.
