MRPL33 and dilated cardiomyopathy: Six mitochondria-associated proteins (mitochondrial 39S ribosomal protein L33, ribosomal recycling factor, mitochondrial leucine-rich pentatricopeptide repeat motif-containing protein, serine protease high-temperature requirement protease A2, mitochondrial peptide methionine sulfoxide reductase, and mitochondrial input endomembrane transporter enzyme subunit translocase of inner mitochondrial membrane 14) and dilated cardiomyopathy were statistically significant, both with P < .05.
