300005.0020; RETT SYNDROME |
| Identified Mutation |
ARG168TER; Wan et al. [Hum. Genet. 65: 1520-1529 (1999)] identified an arg168-to-ter (R168X) mutation in the MECP2 gene in 6 unrelated sporadic cases of Rett syndrome, as well as in 2 affected sisters and their normal mother. |
| Remarks |
Clinically affected; first signs observed at 6 months of age; no hand use; repetitive hand motions; non-verbal; cannot walk; occasional breathing problems; seizures; EEG has minor abnormalities; major eating difficulties; minor gastroesophageal reflux; back has slight curve; small feet; occasional problem with circulation; occasional tremors; some sleep difficulties; donor subject is heterozygous for a 502C>T transition in the MECP2 gene resulting in a premature stop at codon 168 [Arg168Ter (R168X)] |
