Inborn genetic diseases Uncertain:1
The p.I71V variant (also known as c.211A>G), located in coding exon 3 of the YARS gene, results from an A to G substitution at nucleotide position 211. The isoleucine at codon 71 is replaced by valine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species; however, valine is the reference amino acid in other 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.
not provided Uncertain:1
In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 16429158, 27915290)
Charcot-Marie-Tooth disease dominant intermediate C Uncertain:1
This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 71 of the YARS protein (p.Ile71Val). This variant is present in population databases (rs145768628, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with YARS-related conditions. ClinVar contains an entry for this variant (Variation ID: 464875). 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 YARS 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.
