Genes affected
HARS2 (HGNC:4817): (histidyl-tRNA synthetase 2, mitochondrial) Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is an enzyme belonging to the class II family of aminoacyl-tRNA synthetases. Functioning in the synthesis of histidyl-transfer RNA, the enzyme plays an accessory role in the regulation of protein biosynthesis. The gene is located in a head-to-head orientation with HARS on chromosome five, where the homologous genes likely share a bidirectional promoter. Mutations in this gene are associated with the pathogenesis of Perrault syndrome, which involves ovarian dysgenesis and sensorineural hearing loss. Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 08, 2015The c.-4C>G variant in HARS2 has not been previously reported in inviduals with hearing loss. Data from large population studies is insufficient to assess the f requency of this variant. This variant is located within the 5' untranslated reg ion (UTR) of HARS2. Although this variant alters the Kozak sequence, it is uncle ar if a C>G change at this position would impact protein translation. In summary , the clinical significance of the c.-4C>G variant is uncertain. -
