CaseAddInfo: daughter also underwent genetic testing which showed she was a heterozygous carrier for the same variant. She presented with decreased GAA activity in DBS and isolated lymphocytes.

CasePreviousTesting: blood laboratory exams, electromyography study, echocardiogram, biopsy of biceps and deltoid muscles, histochemical staining which showed no abnormalities, electron microscopy, DBS, enzyme activity analyzed in isolated lymphocytes (confirmed decreased GAA activity)
