300005.0008; RETT SYNDROME |
| Identified Mutation |
ARG106TRP; In 2 affected half sisters of a family with Rett syndrome (312750), Amir et al. [Nature Genet. 23: 185-188 (1999)] identified a C-to-T transition at nucleotide 390 of the MECP2 gene, resulting in an ARG106-to-TRP substitution. |
| Remarks |
Clinically affected; donor subject carries a missense mutation, 390C>T, in the gene encoding methyl-CpG binding protein 2 (MECP2) resulting in the change of a conserved amino acid [ARG106TRP (R106W)] in the methyl-binding domain. |
