Mitochondrial RNR1 gene

The mitochondrial gene MT-RNR1 encodes mitochondrial ribosomal RNA (rRNA), the 12S subunit. The gene is encoded by nucleotides 648-1601. Mutations cause sensorineural deafness. The ensemble of all mitochondrial genes is tested if a mitochondrial disorder has to be diagnosed.
