| 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. |

2815_2816delGT |
| Remarks |
Clinically affected; juvenile onset; 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 (IVS1-13T>G) resulting in alternatively spliced transcripts with deletion of the first coding exon, exon 2; the second allele has a 2 bp deletion at nucleotide 2815 (c.2815_2816delGT) resulting in a frameshift and premature stop [Val939fsX78]; also identified in this subject is a third mutation of unknown disease effect: a G>A transition at nucleotide 448 (c.448G>A) resulting in the substitution of threonine for alanine at codon 150 [Ala150Thr (A150T)]; cross-reactive immunological material (CRIM)-positive status confirmed by Western blot and GAA sequencing analyses(PMID:24044919). |
