Fabry nephropathy is a major cause of morbidity and premature death in patients with disease (FD), rare X-linked lysosomal storage disorder. Gb3, the main substrate α-galactosidase A (α-Gal A), progressively accumulates within cells variety tissues. Establishment cell models has been useful as tool for testing hypotheses pathogenesis. We applied CRISPR/Cas9 genome editing technology to GLA gene develop human kidney FD immortalized podocytes, which are affected renal type. Our podocytes lack...
