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; presented at birth with bilateral severe cleft lip and palate, deep sacral dimple, and bilateral hydrocele; hypertrophic cardiomyopathy; hypotonia, head lag, and hepatomegaly noted at age 2 months; deficiency of acid alpha-glucosidase in fibroblasts (0.2 versus control of 31 nmoles substrate hydrolyzed/mg protein); high-resolution chromosomes normal; died at age 14 months; donor subject is a compound heterozygote: one allele has a C>T transition at nucleotide 172 in exon 2 of the GAA gene [172C>T] resulting in a substitution of a termination codon for glutamine at codon 58 [Gln58Stop(Q58X)] and a second allele has a single nucleotide deletion (threonine) at position 525 in exon 2 of the GAA gene [del525T]. |
