Mitochondrial DNA (mtDNA) differs from the nuclear genome in many aspects: a maternal inheritance pattern, being more prone to acquire somatic novo mutations, accumulative with age; and the possible coexistence of different mtDNA alleles (heteroplasmy). Mitochondria are key cellular organelles responsible for energy production, involved in complex...
Introduction
Hypertrophic cardiomyopathy (HCM) is a inherited cardiac disease with a variable penetrance and expressivity. Epigenetics orchestrates the interplay between the environment and the molecular changes that lead to the development of the pathological phenotype. It is of great interest to identify the changes that determine the magnitude o...
