Generation of patient-specific induced pluripotent stem cells (KSCBi007-A) derived from a patient with Prader-Willi syndrome retain maternal uniparental disomy (UPD)


Prader-Willi syndrome (PWS) is a neurodevelopmental disorder caused by loss of paternally expressed genes in an imprinted region of 15q11.2-q13. We established a human-induced pluripotent stem cell (hiPSC) line, KSCBi007-A, from the peripheral blood mononuclear cells of a 5-month-old girl with PWS that retained maternal uniparental disomy (UPD). Methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) of genomic DNA revealed the maternal UPD in the hiPSCs. The generated hiPSC line expressed pluripotency markers and showed the ability to differentiate into three germ layers in vitro. This hiPSC line could be used as a cellular model of an imprinting disorder in humans. Copyright © 2019. Published by Elsevier B.V.
