<p>We report a case of hypertrophic cardiomyopathy and lactic acidosis in a 3-year-old female. Cardiac and skeletal muscle biopsies exhibited mitochondrial hyperplasia with decreased complex VI activity. Whole exome sequencing identified compound heterozygous variants, p.Arg333Trp and p.Val119Leu, in <a href="https://www.ncbi.nlm.nih.gov/gene/10102">TSFM</a>, a nuclear gene that encodes a mitochondrial translation elongation factor, resulting in impaired oxidative phosphorylation and juvenile hypertrophic cardiomyopathy.</p>
