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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with aspartic acid, which is acidic and polar, at codon 505 of the HARS2 protein (p.Glu505Asp). This variant is present in population databases (rs370053420, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with HARS2-related conditions. ClinVar contains an entry for this variant (Variation ID: 517495). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The aspartic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1515G>T (p.E505D) alteration is located in exon 13 (coding exon 13) of the HARS2 gene. This alteration results from a G to T substitution at nucleotide position 1515, causing the glutamic acid (E) at amino acid position 505 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Jul 25, 2017

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

p.Glu505Asp in exon 13 of HARS2: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, elephant, shrew, manatee, tenrec and aardvark have an Asp at this position despite high nearby amino acid conservation. In addition, computational predict ion tools do not suggest a high likelihood of impact to the protein. It has been identified in 0.1% (23/18870) of East Asian chromosomes by the Genome Aggregati on Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs370053420). -
