Generation of induced pluripotent stem cell lines carrying monoallelic (UCSFi001-A-60) or biallelic (UCSFi001-A-61; UCSFi001-A-62) frameshift variants in CACNA1A using CRISPR/Cas9

[摘要] CACNA1A encodes a P/Q-type voltage-gated calcium channel. Heterozygous loss-of-function variants in this gene have been associated with episodic ataxia type 2. In this study, we used CRISPR/Cas9 to generate isogenic human induced pluripotent stem cell lines with a gene-dosage dependent deficiency of CACNA1A. We obtained one clone with monoallelic (UCSFi001-A-60) and two clones with biallelic (UCSFi001-A-61; UCSFi001-A-62) frameshift variants in CACNA1A. All three lines showed expression of pluripotency markers and a normal karyotype.
