Abstract
Essential hypertension (EH) is a common complex disorder with high heritability. Maternal inherited pattern was observed in some families with EH, which was known as maternally inherited essential hypertension (MIEH). Mitochondrial DNA (mtDNA) mutations were identified to account for some MIEH in previous studies. In the present study, we characterized clinical manifestations and the complete mitochondrial genome of a Chinese family with MIEH. Through analyzing the whole mtDNA genome of the proband, we identified a mutation m.5512A > G in the MT-TW gene that changed a highly conserved nucleotide and could potentially affect the function of tRNATrp. Furthermore, significantly exercise intolerance, left ventricular remodeling and increased arterial stiffness were observed in carriers with mutation m.5512A > G, which further supported the potentially pathogenic effect of m.5512A > G in MIEH.
