| Allelic Variant 2 |
606800.0014; GLYCOGEN STORAGE DISEASE TYPE II |
| Identified Mutation |
1-BP DEL, 525T; In a girl with the juvenile form of Pompe disease (232300), Hermans et al. (1994) identified compound heterozygosity for 2 mutations in the GAA gene: P545L (606800.0013) and a 1-bp deletion (525delT), resulting in premature termination of the protein at nucleotide positions 658 to 660. |
| Remarks |
Clinically affected; absent acid-alpha-1,4 glucosidase activity; donor subject is a compound heterozygote: one allele has a C>A transversion at position -3 of the acceptor site of intron 1 of the GAA gene (c.-32-3C>A); the second allele has a 1 bp deletion at nucleotide 525 in exon 2 (c.525delT) resulting in a frameshift and premature termination of the protein [Glu176fsX45) |
