Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4BS2
The NM_004100.5(EYA4):c.529G>A(p.Val177Ile) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000434 in 1,613,810 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★).

The p.Val177Ile variant in EYA4 has not been previously reported in individuals with hearing loss, but has been identified in 4/66718 European chromosomes by th e Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conserv ation analyses do not provide strong support for or against an impact to the pro tein. In summary, the clinical significance of the p.Val177Ile variant is uncert ain. -
Variant summary: EYA4 c.529G>A (p.Val177Ile) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 3.6e-05 in 251274 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.529G>A in individuals affected with Dilated Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. Co-occurrence with a pathogenic variant has been reported (MYBPC3 c.2308G>A, p.D770N), providing supporting evidence for a benign role. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Both laboratories classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 177 of the EYA4 protein (p.Val177Ile). This variant is present in population databases (rs776409783, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with EYA4-related conditions. ClinVar contains an entry for this variant (Variation ID: 228681). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt EYA4 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. -

Has not been previously published as pathogenic or benign to our knowledge; In silico analysis supports that this missense variant does not alter protein structure/function -
Cardiovascular phenotype Uncertain:1
The p.V177I variant (also known as c.529G>A), located in coding exon 7 of the EYA4 gene, results from a G to A substitution at nucleotide position 529. The valine at codon 177 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
