Abstract
The human induced pluripotent stem cell (iPSC) lines, CSUXHEi001-A and CSUXHEi002-A, were generated from peripheral blood mononuclear cells (PBMCs). The donors were couple and each of them has a heterozygous mutation in the SLC26A4 gene. It manifests in their children as Enlarged vestibular aqueduct (EVA). The use of iPSC will allow describing the early stages of hearing loss, which is undoubtedly relevant for identifying key stages of development at which phenotypic manifestations of mutations in the SLC26A4 gene are found.
