Abstract

Familial hypercholesterolemia (FH) is a genetic disorder affecting the metabolism of lipoprotein, characterized by elevated levels of plasma concentrations of low-density lipoprotein cholesterol (LDLC). The most common FH cause is mutations within the gene that encodes for the LDL receptor (LDLR) protein. Two induced pluripotent stem cell (iPSC) lines were generated from patients with FH, each carrying a single heterozygous mutation in the LDLR gene, one is a missense mutation, c.631C > T, and the other is a splice-site mutation, c.313 + 1G > A. Both iPSC lines exhibited strong expression of pluripotency markers, demonstrated the ability to differentiate into derivatives of the three germ layers, and maintained normal karyotypes. These derived iPSC lines represent powerful tools for in vitro modeling FH and offer a promising platform for therapeutic development.

摘要

家族性高胆固醇血症(FH)是一种影响脂蛋白代谢的遗传性疾病,其特征是血浆中低密度脂蛋白胆固醇(LDLC)浓度升高。最常见的 FH 病因是编码 LDL 受体(LDLR)蛋白的基因突变。从 FH 患者中生成了两条诱导多能干细胞(iPSC)系,每条系都携带 LDLR 基因中的单个杂合突变,一个是错义突变,c.631C>T,另一个是剪接位点突变,c.313+1G>A。两条 iPSC 系均表现出强烈的多能性标记物表达,显示出分化为三个胚层衍生物的能力,并维持正常核型。这些衍生的 iPSC 系代表了 FH 体外建模的有力工具,并为治疗开发提供了有前途的平台。
