17q25.2-q25.3 |
| 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. |

| Identified Mutation |
EX18DEL; Van der Kraan et al. [Biochem. Biophys. Res. Commun. 203: 1535-1541 (1994)] reported that deletion of exon 18 of the GAA gene is a frequent mutation in Pompe disease (232300). Huie et al. [Hum. Molec. Genet. 3: 2231-2236 (1994)] found this mutation in patients with both infantile and adult forms of this disease. Vorgerd et al. [Neurogenetics 1: 205-211 (1998)] found homozygosity for the exon 18 deletion in 2 affected sibs and an unrelated patient with adult type GSD II. |
| Remarks |
Abnormal liver function tests; occasional charley-horse in legs during physical activity; morning headaches; intolerance to greasy foods; abdominal cyst; deficient fibroblast and WBC acid-alpha-1,4 glucosidase activity; donor subject is a compound heterozygote: allele one carries a T>G transversion at position -13 of the acceptor site of intron 1 of the GAA gene (IVS1-13T>G); the resulting alternatively spliced transcript has an in frame deletion of exon 2 which contains the initiation codon; allele two carries a deletion of exon 18 |
