A human induced pluripotent stem cell (iPSC) line was generated from a female patient affected by autosomal recessive retinitis pigmentosa with two mutations in the USH2A gene: c.2209C > T (p.Arg737Ter) and c.8693A > C (p.Tyr2898Ser). Skin fibroblasts were infected with Sendai virus containing the Yamanaka factors and the resulting cells were fully characterized to confirm successful reprogramming. The iPSC line expressed several pluripotency markers, could generate the three germ layers, had a normal karyotype, carried the two USH2A mutations and was free of Sendai virus. This cell line will serve as a model to unravel the pathogenic mechanisms underlying USH2A-associated retinal degeneration.
