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]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 05, 2023The c.410G>A (p.R137Q) alteration is located in exon 5 (coding exon 5) of the HARS gene. This alteration results from a G to A substitution at nucleotide position 410, causing the arginine (R) at amino acid position 137 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Usher syndrome type 3B Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 19, 2024This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 137 of the HARS protein (p.Arg137Gln). This variant is present in population databases (rs191391414, gnomAD 0.02%). This missense change has been observed in individual(s) with HARS-related conditions (PMID: 22930593, 27353947, 29790872). ClinVar contains an entry for this variant (Variation ID: 40062). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt HARS protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects HARS function (PMID: 22930593, 32543048). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
