not specified Pathogenic:1
The p.H472R variant (also known as c.1415A>G), located in coding exon 11 of the GARS gene, results from an A to G substitution at nucleotide position 1415. The histidine at codon 472 is replaced by arginine, an amino acid with highly similar properties. This variant (also referred to as p.H418R) has been reported in multiple patients with distal hereditary motor neuropathy (also called distal spinal muscular atrophy) and has been shown to segregate with disease (Sivakumar K et al. Brain, 2005 Oct;128:2304-14; Schabhüttl M et al. J. Neurol., 2014 May;261:970-82; Karakaya M et al. Hum. Mutat., 2018 09;39:1284-1298). Functional studies of this alteration demonstrate reduced aminoacylation activity, substantial reductions in yeast viability, and altered cellular localization in transfected mouse motor neuron cell lines (Griffin LB et al. Hum. Mutat., 2014 Nov;35:1363-71; Antonellis A et al. J. Neurosci., 2006 Oct;26:10397-406). In addition to the clinical data presented in the literature, this alteration is absent in population-based cohorts in the Genome Aggregation Database (gnomAD) and predicted to be deleterious by in silico analysis. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
Charcot-Marie-Tooth disease type 2 Pathogenic:1
This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 472 of the GARS protein (p.His472Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with peripheral neuropathy (PMID: 16014653, 24627108). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 410314). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on GARS protein function. Experimental studies have shown that this missense change affects GARS function (PMID: 25168514). For these reasons, this variant has been classified as Pathogenic. -
