Genes affected
TRMT10C (HGNC:26022): (tRNA methyltransferase 10C, mitochondrial RNase P subunit) This gene encodes the precursor of a subunit of the mitochondrial ribonuclease P, which is involved in 5' processing of mitochondrial tRNAs. The encoded protein may confer RNA-binding capacity to mitochondrial ribonuclease P and may be essential for transcript processing, RNA modification, translation and mitochondrial respiration.
