Germline missense mutations in the BAF swi/snf chromatin remodeling subunit SMARCA4 are associated with neurodevelopmental disorders, including Coffin Siris Syndrome (CSS). Here, we generated an induced pluripotent stem cell line from a male patient with atypical CSS features and a de novo heterozygous missense mutation in the SMARCA4 gene (c.3607C>T, p.(Arg1203Cys)). Hair root derived keratinocytes were reprogrammed using non-integrative Sendai virus vector delivery of pluripotency factors. iPSCs generated display normal morphology and molecular karyotype, express pluripotency markers and are able to differentiate into the three germ layers.
胚系错义突变导致 BAF 染色质重塑亚基 SMARCA4 基因突变与神经发育障碍相关,包括 Coffin-Siris 综合征(CSS)。本研究中,我们从一位具有非典型 CSS 特征的男性患者中建立了诱导多能干细胞系,该患者携带 SMARCA4 基因的从头杂合错义突变(c.3607C>T,p.(Arg1203Cys))。利用非整合型 Sendai 病毒载体传递多能性因子对发根来源的角质形成细胞进行重编程。生成的 iPS 细胞具有正常的形态和分子核型,表达多能性标志物,并能分化为三个胚层。
