Generation of induced pluripotent stem cells from a patient with hearing loss carrying OPA1 c.1468T>C (p.Cys490Arg) variant


Pathogenic variants of OPA1 have been associated with autosomal dominant optic atrophy (DOA), leading to optic, auditory, and other sensorineural neuropathies and myopathies. Using the Sendai virus delivery system, we generated induced pluripotent stem cells from the peripheral blood mononuclear cells of a female patient with the OPA1 pathogenic variant c.1468T>C (p.Cys490Arg). 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 is a useful platform for investigating the pathogenic mechanisms of both blindness and deafness related to OPA1 variants. Copyright © 2022 The Authors. Published by Elsevier B.V.
