Generation of human induced pluripotent stem cell lines derived from four patients with a pathogenic ALPK3 variant associated with adult-onset hypertrophic cardiomyopathy (HCM)

Résumé fourni par la source

Loss of function variants in ALPK3 have been associated with dilated cardiomyopathy (DCM) and hypertrophic cardiomyopathy (HCM). However, the underlying pathomechanism remain largely unknown. Here, we generated human iPSC lines from four HCM patients carrying the heterozygous pathogenic variant in ALPK3 (c.2023delC p.Gln675fs). Peripheral blood mononuclear cells (PBMCs) from patients were reprogrammed to induced pluripotent stem cells (iPSCs) with the Sendai virus-based reprogramming method. All four lines display typical iPSC morphology, normal karyotype, expression of pluripotency-associated markers, and trilineage differentiation potential. These iPSC lines represent a valuable resource of ALPK3 patient-derived iPSC lines to the study ALPK3-associated cardiomyopathy.
