Genes affected

HARS1 (HGNC:4816): (histidyl-tRNA synthetase 1) Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is a cytoplasmic enzyme which belongs to the class II family of aminoacyl-tRNA synthetases. The enzyme is responsible for the synthesis of histidyl-transfer RNA, which is essential for the incorporation of histidine into proteins. The gene is located in a head-to-head orientation with HARSL on chromosome five, where the homologous genes share a bidirectional promoter. The gene product is a frequent target of autoantibodies in the human autoimmune disease polymyositis/dermatomyositis. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

c.1312-8C>T in intron 11 of HARS: This variant is not expected to have clinical significance because a C>T change at this position does not diverge from the spl ice consensus sequence and is therefore unlikely to impact splicing. It has been identified in 5/66712 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). -
