| Identified Mutation |
THR158MET; In a sporadic patient with Rett syndrome (312750), Amir et al. [Nature Genet. 23: 185-188 (1999)] identified a C-to-T transition at nucleotide 547 of the MECP2 gene, resulting in a THR158-to-MET (T158M) substitution. |
| Remarks |
Clinically affected; some seizures, loss of purposeful hand use; repetitive hand motions; nonverbal; acquired microcephaly; small feet; some problems with circulation; constipation; some teeth grinding; EEG showed significant abnormalities; eating problems with some reflux; nonambulatory with jerky truncal ataxia; breath holding; balanced t(8;12) inherited from mother; in addition, the donor subject carries a C>T transition at nucleotide 473 (ACG>ATG) in exon 3 of the gene encoding methyl-CpG binding protein 2 (MECP2) resulting in the substitution of threonine 158 by methionine [THR158MET (T158M)] in the methyl-binding domain. |
