300005.0003; RETT SYNDROME |
| Identified Mutation |
806delG; In a woman with motor coordination problems, mild learning disability, and skewed X inactivation, Wan et al. (Am J Hum Genet 65:1520-1529,1999) identified a 1-bp deletion (806delG) in the MECP2 gene, resulting in a val288-to-ter (V288X) substitution in the transcription repression domain. The same mutation was found in her sister and daughter, who were affected with classic Rett syndrome (312750), and in her hemizygous son, who died from congenital encephalopathy (300673). |
| Remarks |
Clinically affected; classic phenotype; affected niece is GM21913; donor subject has a 1 bp deletion at nucleotide 806 in exon 3 of the MECP2 gene (806delG) resulting in a premature stop codon at 288 [Val288Ter (V288X)] |
