Variant summary
Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4
The NM_002109.6(HARS1):c.244C>T(p.Arg82Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000105 in 1,613,470 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. R82R) has been classified as Likely benign.

Submissions by phenotype
not provided Uncertain:1
The HARS1 c.244C>T; p.Arg82Cys variant (rs769340873), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 568450). This variant is absent from the Genome Aggregation Database (v2.1.1), indicating it is not a common polymorphism. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.256). Due to limited information, the clinical significance of this variant is uncertain at this time. -
Usher syndrome type 3B Uncertain:1
This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 82 of the HARS protein (p.Arg82Cys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with HARS-related conditions. ClinVar contains an entry for this variant (Variation ID: 568450). 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 not expected to disrupt HARS protein function with a negative predictive value of 80%. 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. -
