enzyme activity in fibroblast was recorded to be 5.4 nmol/h/mg protein.

Patient1: the efficacy of AMOs 1, 2, and 3 were tested in cultured fibroblasts from this patient

Under basal conditions, the fibroblasts retained 20% enzymatic activity compared to WT cells; treatment with combination of the AMOs showed rescue of normally spliced GAA mRNA, this was confirmed with real-time qPCR
