In a woman with adult-onset glycogen storage disease II (GSD2; 232300), Hermans et al. (1994) identified a homozygous 1634C-T transition in the GAA gene, resulting in a pro545-to-leu (P545L) substitution. She was diagnosed at age 42 years and died at age 51 years. This mutation was compatible with normal synthesis, but hindered enzyme activity and resulted in 92% loss of GAA activity. Another unrelated girl with juvenile-onset GSD II was compound heterozygous for P545L and 525delT (606800.0014).
