GCDH encodes for the enzyme catalyzing the sixth step of the lysine catabolism pathway. Biallelic pathogenic variants in GCDH have been associated with glutaric aciduria type 1 (GA1). In this study CRISPR/Cas9 technology was used to create an isogenic GCDH knock-out human iPSC line. One clone with a biallelic deletion (SCTCi019-A) in GCDH was obtained and fully characterized, revealing a normal karyotype, no off-targets detected and expression of pluripotency markers. This iPSC line can contribute to gain insights in the molecular mechanism of disease.
GCDH 编码催化赖氨酸分解代谢途径第六步的酶。GCDH 中的双等位致病性变异与 1 型戊二酸血症（GA1）有关。在这项研究中，使用 CRISPR/Cas9 技术创建了同源 GCDH 敲除的人类 iPSC 系。获得了一个在 GCDH 中具有双等位缺失（SCTCi019-A）的克隆，并对其进行了全面表征，显示正常核型、未检测到脱靶和多能性标记物的表达。该 iPSC 系可有助于深入了解疾病的分子机制。
