Establishment of an iPSC line (CSUXHi004-A) from a patient with Waardenburg syndrome type I caused by a PAX3 splice mutation


Waardenburg Syndrome (WS) is a common autosomal dominant syndrome associated with hearing loss. Its clinical manifestations include hearing impairment and pigmentation anomalies. In this study, we generated an induced pluripotent stem cell (iPSC) line from the Epstein-Barr virus-immortalized B lymphocytes of a 6-year-old boy affected with WS type I, caused by a heterozygous splice site mutation in the PAIRED BOX GENE 3 (PAX3) (NM_181457.3: c.452-2A > G). The patient-specific iPSC line (CSUXHi004-A) carrying the same PAX3 mutation showed a normal karyotype, expressed pluripotent markers, and presented differentiation capacity in vitro. This method may be a useful tool for the in vitro modeling of WS. Copyright © 2021 The Authors. Published by Elsevier B.V. All rights reserved.
