Pathogenic variants of the WFS1 gene can cause recessive-inherited Wolfram syndrome or dominant-inherited Wolfram-like syndrome with optic atrophy and hearing impairment. Using the Sendai virus delivery system, we generated induced pluripotent stem cells from the peripheral blood mononuclear cells of a female patient with the WFS1 pathogenic variant c.2051C > T (p.Ala684Val). The resulting induced pluripotent stem cells exhibited a normal karyotype and pluripotency, as confirmed using immunofluorescence staining, and differentiated into three germ layers in vivo. This cellular model provides a useful platform for investigating the pathogenic mechanisms of both blindness and deafness related to WFS1 variants.
