Genes affected

MRM2 (HGNC:16352): (mitochondrial rRNA methyltransferase 2) The protein encoded by this gene is a member of the S-adenosylmethionine-binding protein family. It is a nucleolar protein and it may be involved in the processing and modification of rRNA. This gene has been suggested to be involved in cell cycle control and DNA repair.
