Generation of three human induced pluripotent stem cell lines, LUMCi024-A, LUMCi025-A, and LUMCi026-A, from two patients with combined oxidative phosphorylation deficiency 8 and a related control


Combined Oxidative Phosphorylation Deficiency 8 (COXPD8) is an autosomal recessive disorder causing lethal childhood-onset hypertrophic cardiomyopathy. Homozygous or compound heterozygous mutations in the nuclear-encoded mitochondrial alanyl-tRNA synthetase 2 (AARS2) gene underly the pathology. We generated induced pluripotent stem cells (hiPSCs) from two patients carrying the heterozygous compound c.1774 C>T, c.2188 G>A and c.2872 C>T AARS2 mutations, as well as a related healthy control carrying the c.2872 C>T AARS2 mutation. All hiPSC-lines expressed pluripotency markers, maintained a normal karyotype, and differentiated towards the three germ layer derivatives in vitro. These lines can be used to model COXPD8 or mitochondrial dysfunction. Copyright © 2021. Published by Elsevier B.V.
