Generation of a human iPSC line, INMi007-A, carrying compound heterozygous DCT variants associated with oculocutaneous albinism type 8

Abstract

Pathogenic variants in the Dopachrome tautomerase (DCT) gene (NM_001129889.2) have recently been associated with a novel oculocutaneous albinism (OCA) subgroup, type 8 (OCA8). Here, we report the establishment of an induced pluripotent stem cell (iPSC) line, INMi007-A, derived from the skin fibroblasts of an individual compound heterozygous for two pathogenic variants in DCT, using the non-integrative Sendai virus reprogramming method. This iPSC line harbors a single-nucleotide variant in exon 1 of DCT (c.118T > A; p.(Cys40Ser)) and a 14-bp deletion in exon 9 (c.1406_1419del; p.(Phe469*)). This cell line represents an important tool for studying the pathophysiology of OCA8.
