Generation of a gene corrected human isogenic iPSC line (CPGHi001-A-1) from a hearing loss patient with the TMC1 p.M418K mutation using CRISPR/Cas9

Abstract

TMC1 p.M418K mutation is homologous to that in Beethoven mice, which may induce autosomal dominant non-syndromic progressive hearing loss. Previously, we generated an induced pluripotent stem cells (iPSCs) line (CPGHi001-A) from a hearing loss patient with the TMC1 c.1253 T > A (p.M418K) mutation. Here we genetically corrected the TMC1 c.1253 T > A mutation using CRISPR/Cas9 technology to generate an isogenic control, CPGHi001-A-1. The resulting iPSCs had a normal karyotype, showed pluripotency by immunofluorescence staining, and differentiated into the three germ layers in vitro.
