The HARS2 gene encodes for a protein called histidyl-tRNA synthetase 2. This gene is involved in the process of protein synthesis, specifically in attaching the amino acid histidine to its corresponding transfer RNA molecule.

Changes or mutations in the HARS2 gene have been linked to a rare genetic disorder known as Perrault syndrome. This syndrome is characterized by hearing loss, changes in ovarian function, and sometimes other neurological problems.

Scientists have conducted research on the HARS2 gene to better understand its function and its role in health and disease. Numerous articles and references on this gene can be found in scientific databases such as PubMed and OMIM. In addition, there are genetic testing resources and registries that list the HARS2 gene as a target for testing in cases of suspected Perrault syndrome or related conditions.

This putative disease-causing gene has been identified as a potential candidate for testing and further scientific investigation. Genetic testing for mutations in the HARS2 gene can provide additional information for individuals and families at risk of developing Perrault syndrome or related conditions.
