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. |

T737N; GLYCOGEN STORAGE DISEASE TYPE II |
| Identified Mutation |
THR737ASN |
| Remarks |
Clinically affected; probable classic infantile onset; no specific information provided as to enzyme activity or cardiac status and therefore could be an atypical infantile onset; donor subject is a compound heterozygote: one allele has a 1 bp deletion at nucleotide 525 in exon 2 of the GAA gene (c.525delT) resulting in a frameshift and premature termination of the protein [Glu176fsX45); the second allele has a C>A transversion at nucleotide 2210 (c.2210C>A) resulting in the substitution of asparagine for threonine at codon 737 [Thr737Asn (T737N)]; cross-reactive immunological material (CRIM)-positive status confirmed by Western blot and GAA sequencing analyses(PMID:24044919). |
