| Allelic Variant 2 |
606800.0017; GLYCOGEN STORAGE DISEASE TYPE II, ADULT FORM |
| Identified Mutation |
GLY293ARG |
| Remarks |
Clinically affected; deficient acid-alpha-1,4 glucosidase activity (0.5%); donor subject is a compound heterozygote: one allele has an A>G transition at position -2 of the acceptor site of intron 1 of the GAA gene (c.-32-2A>G); the second allele has a G>A transition at nucleotide 877 in exon 5 resulting in the substitution of arginine for glycine at codon 293 [Gly293Arg (G293R)] |
