Abstract

The X-linked lysosomal storage disorder Fabry disease originates from GLA gene mutations causing α-galactosidase A enzyme deficiency. Here we generated the GLA knockout hiPSC line MHHi001-A-15 (GLA-KOhiPSC) as an in vitro Fabry disease model by targeting exon 2 of the GLA gene by CRISPR/Cas9 in the established control hiPSC line MHHi001-A. GLA-KOhiPSCs retained the expression of pluripotency markers, trilineage differentiation potential, as well as normal karyotype and stem cell morphology but lacked α-galactosidase A enzyme activity. The GLA-KOhiPSCs represent a potent resource to not only study the Fabry disease manifestation but also screen for novel treatment options.
