Mental Retardation, X-linked 19; Mrx19

Description

X-linked mental retardation-19 (MRX19) is a nonsyndromic form of mild to moderate mental retardation. Carrier females may be mildly affected. Mutation in the RPS6KA3 gene also causes Coffin-Lowry syndrome (CLS ), a mental retardation syndrome with dysmorphic facial features and skeletal anomalies. Some patients with RPS6KA3 mutations have an intermediate phenotype with mental retardation and only mild anomalies reminiscent of CLS. These individuals have mutations resulting in some residual protein function, which likely explains the milder phenotype (summary by Field et al., 2006).
