Cone dystrophy with supernormal rod response (CDSRR) is associated with pathogenic variants of the KCNV2 gene that result in severe symptoms, including color vision defects, decreased visual acuity, and specific changes in electroretinogram responses. Two iPSC lines were obtained from two patients in the same family with different types of mutations in the KCNV2 gene. These lines could serve as a useful model for studying the pathogenetic mechanism and treatment development for CDSRR. PBMCs from donors have been reprogrammed into iPSC lines. Derived clones were characterized with mutation sequencing, analysis of common pluripotency-associated markers at the protein levels, and in vitro differentiation studies.
