Genes affected

MT-TF (HGNC:7481): (mitochondrially encoded tRNA phenylalanine)

TRNF (HGNC:):

MT-RNR1 (HGNC:7470): (mitochondrially encoded 12S RNA) Enables DNA binding activity and DNA-binding transcription factor binding activity. Involved in several processes, including osteoblast proliferation; regulation of carbohydrate utilization; and regulation of phosphate metabolic process. Located in extracellular space; mitochondrion; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]
