Generation of an induced pluripotent stem cell line carrying a biallelic deletion (SCTCi019-A) in GCDH using CRISPR/Cas9

Abstract

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.
