Interventional, cross-sectional biomedical study of children with genetic cardiomyopathy and healthy children. The aim is to generate, via induced human pluripotent stem cells (hiPSC), patient-specific cardiomyocytes (CMs) (hiPSC-CMs) to study the molecular mechanisms of cardiomyopathies of genetic origin.~The study will be proposed to the parents or legal guardians of the children from 0 to 17 included sent in pediatric cardiology consultation to the University Hospital of Montpellier as part of their usual follow-up or a health check (control) .~The only direct intervention performed on the patient is a venous blood sample. The volume of blood collected will be lower than the thresholds defined in the Decree of December 2nd, 2016 on minimal risks in biomedical research (3 ml).
