Generation of three induced pluripotent stem cell lines from a patient with Usher syndrome caused by biallelic c.949C > A and c.1256G > T mutations in the USH2A gene

Abstract

Mutations in the USH2A gene are the most common cause of Usher syndrome and autosomal recessive non-syndromic retinitis pigmentosa. Here, we describe the generation of three induced pluripotent stem cell lines from dermal fibroblasts derived from a patient carrying biallelic c.949C > A and c.1256G > T variants in the USH2A gene, using episomal reprogramming plasmids expressing OCT4, SOX2, KLF4, MYCL, LIN28, mir302/367 and shRNA targeting TP53. All three lines expressed pluripotency markers, displayed unaltered karyotypes as well as trilineage differentiation potential, and were negative for reprogramming episomes and mycoplasma.
