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]

The p.S356N variant (also known as c.1067G>A), located in coding exon 10 of the HARS gene, results from a G to A substitution at nucleotide position 1067. The serine at codon 356 is replaced by asparagine, an amino acid with highly similar properties. This variant was detected in an individual with Charcot-Marie-Tooth disease and in an unaffected parent (Abbott JA et al. Hum Mutat, 2018 03;39:415-432). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 356 of the HARS protein (p.Ser356Asn). This variant is present in population databases (rs144322728, gnomAD 0.004%). This missense change has been observed in individual(s) with Charcot-Marie-Tooth disease (PMID: 29235198). ClinVar contains an entry for this variant (Variation ID: 446301). 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. Experimental studies have shown that this missense change affects HARS function (PMID: 29235198). 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. -
