Gene: Mecp2  Location: ChrX:74026592-74085690 bp, - strand  Genetic Position: ChrX, 37.63 cM
Germline Transmission:  Earliest citation of germline transmission: J:127431
Parent Cell Line:  Not Specified (ES Cell)

Allele Type:    Targeted (Humanized sequence)
Mutations:    Insertion, Single point mutation
Mutation detailsThe targeting vector was created by using site-directed mutagenesis to introduce an AGA-->TGA (arginine-->stop) substitution into amino acid 168 in exon 4. The nonsense point mutation creates an R168X amino acid substitution in the methyl-CpG binding domain. This mutation corresponds to one of the most common MeCP2 mutations associated with human Rett syndrome. The targeting vector also inserted a loxP-flanked neomycin resistance cassette (neo). Cre-mediated recombination removed the floxed neo cassette. The substitution was confirmed by sequencing. (J:127431)
