Timothy syndrome, an extremely rare disease, is closely associated with a mutation in CACNA1C gene, which encodes the cardiac L-type voltage-gated calcium channel (Cav1.2). In this study, we generated a human induced pluripotent stem cell (iPSC) line from a Timothy syndrome infant carrying heterozygous CACNA1C mutation (transcript variant NM_000719.7c.1216G>A: p.G406R). The generated iPSC line showed typical stem cell morphology, positively expressed pluripotency and proliferation markers, normal karyotype, and trilineage differentiation potential. Therefore, this patient-specific iPSC can be of great significance in investigating the mechanisms underlying Timothy syndrome, and hence establishing effective intervention strategies.
Timothy 综合征是一种极其罕见的疾病，与 CACNA1C 基因突变密切相关，该基因编码心脏 L 型电压门控钙通道（Cav1.2）。在本研究中，我们从携带 CACNA1C 突变（转录变体 NM_000719.7c.1216G>A：p.G406R）的 Timothy 综合征婴儿中生成了一个人诱导多能干细胞（iPSC）系。生成的 iPSC 系表现出典型的干细胞形态，阳性表达多能性和增殖标志物，正常核型和三系分化潜能。因此，这种患者特异性的 iPSC 对于研究 Timothy 综合征的发病机制具有重要意义，并因此建立有效的干预策略。
