Genes affected

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]

1008A>G variant in MTRNR1: This variant has been reported at a similar frequency in individuals with hearing loss (0.2%; 1/466) and in controls (0.3%; 1/400) s upporting a benign role (Konings 2008). In addition, it has been reported in thr ee other individuals who were screened for phylogenetic studies (Palanichamy 200 4, Behar 2008a, Behar 2008b, MITOMAP: http://www.mitomap.org/MITOMAP). In summar y, there is no data to support a disease-associated role and the population freq uency suggests that this variant is likely benign. -
