Generation of two induced pluripotent stem cell lines (CHOCi002-A and CHOCi003-A) from Pompe disease patients with compound heterozygous mutations in the GAA gene

Abstract

Pompe disease is an autosomal recessive lysosomal storage disease caused by pathogenic variants in GAA, which encodes an enzyme integral to glycogen catabolism, acid α-glucosidase. Disease-relevant cell lines are necessary to evaluate the efficacy of genotype-specific therapies. Dermal fibroblasts from two patients presenting clinically with Pompe disease were reprogrammed to induced pluripotent stem cells using the Sendai viral method. One patient is compound heterozygous for the c.258dupC (p.N87QfsX9) frameshift mutation and the c.2227C>T (p.Q743X) nonsense mutation. The other patient harbors the c.-32-13T>G splice variant and the c.1826dupA (p.Y609X) frameshift mutation in compound heterozygosity.
