Abstract

E192K missense mutation of TPM1 has been found in different types of cardiomyopathies (e.g., hypertrophic cardiomyopathy, dilated cardiomyopathy, and left ventricular non-compaction), leading to systolic dysfunction, diastolic dysfunction, and/or tachyarrhythmias. Here, we generated a heterozygous TPM1-E192K knock-in human induced pluripotent stem cell (iPSC) line using CRISPR/Cas9-based genome editing system. The cells exhibit normal karyotype, typical stem cell morphology, expression of pluripotency markers and differentiation ability into three germ layers. Accordingly, this cell line could provide a useful cell resource for exploring the pathogenic role of TPM1-E192K mutation in different types of cardiomyopathies.
