Waardenburg syndrome (WS) is a genetic disorder characterized by sensorineural deafness. It has a variable presentation of pigmentation defects. Here, we generated an induced pluripotent stem cell (iPSC) line using episomal plasmid vectors from the fibroblasts of a 4-year-old boy affected with WS type II, caused by a novel mutation in microphthalmia-associated transcription factor (MITF) (NM_000248.3: exon6:c.626A>T). The patient-specific iPSC line (CSUXHi003-A) carrying the same MITF mutation showed normal karyotype, expressed pluripotent markers, and presented differentiation capacity in vitro. It may be a useful tool for in vitro modeling of WS.
瓦登伯革氏综合征（WS）是一种以感音神经性耳聋为特征的遗传性疾病。它具有色素沉着缺陷的多种表现形式。在此，我们使用来自一名4岁患有II型WS男孩的成纤维细胞，通过游离质粒载体生成了诱导多能干细胞（iPSC）系，该男孩的疾病由小眼相关转录因子（MITF）的一个新突变（NM_000248.3：外显子6：c.626A>T）引起。携带相同MITF突变的患者特异性iPSC系（CSUXHi003-A）显示出正常的核型，表达多能性标志物，并在体外具有分化能力。它可能是用于WS体外建模的有用工具。
