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]

1107T>C in MTRNR1: This variant is not expected to have clinical significance as it is common and at similar afrequencies in individuals with hearing loss and i n controls (Li 2005, Tang 2007, Bilal 2008, Lu 2010, http://www.mtdb.igp.uu.se). Moreover, this region of mitochondrial DNA is not evolutionarily conserved (Lu 2010) and this variant is part of known polymorphisms associated with mitochond rial haplogroups (Tanaka 2004, Lu 2010). In summary, there is no clear data to s upport a disease-associated role or risk for ototoxicity and the population freq uency of the variant suggests that it is benign. -
