| Allelic Variant 1 |
606800.0006; GLYCOGEN STORAGE DISEASE TYPE II, ADULT FORM |
| Identified Mutation |
IVS1AS, T>G, -13; Huie et al. [Hum. Molec. Genet. 3: 2231-2236 (1994)] identified a T-to-G transversion at position -13 of the acceptor site of intron 1 of the GAA gene, resulting in alternatively spliced transcripts with deletion of the first coding exon, exon 2, in patients with the adult onset form of Pompe disease (232300). This mutation was found in 28 of 41 adult onset cases examined. Kroos et al. [J. Med. Genet. 32: 836-837 (1995)] showed this mutation in 38 of 50 heterozygous persons with the adult form of the disease and in 4 of 13 heterozygous patients with juvenile form, but did not find the mutation in children with the infantile form of Pompe disease. |

S627F; GLYCOGEN STORAGE DISEASE TYPE II |
| Identified Mutation |
SER627PHE |
| Remarks |
Clinically affected; progressive muscle weakness; acid alpha-1,4-glucosidase deficiency; donor subject is a compound heterozygote: one allele has a T>G transversion at position -13 of the acceptor site of intron 1 of the GAA gene (c.-32-13T>G) resulting in alternatively spliced transcripts with deletion of the first coding exon, exon 2; the second allele has a C>T transition at nucleotide 1880 (c.1880C>T) resulting in the substitution of phenylalanine for serine at codon 627 [Ser627Phe (S627F)] |
