Generation and characterization of induced pluripotent stem cell (iPSC) lines from patients affected with Tay-Sachs...

Tay-Sachs and Sandhoff diseases, are sphingolipidoses caused by rare genetic mutations in the HEXA and HEXB genes, that encode the alpha and beta subunits of lysosomal hexosaminidase, respectively. Here, we report the generation and characterization of three Tay-Sachs and one Sandhoff iPSC lines derived from patients with late-onset disease carrying mutations at the HEXA or HEXB gene. The Tay-Sachs patients carried either homozygous or complex heterozygous mutations in the HEXA gene. The Sandhoff patient carried a heterozygous mutation in the HEXB gene. These four iPSC lines will serve as a valuable resource for the development of in vitro lysosomal storage disease models and therapeutic drug development.
