ClinVar
Submissions by phenotype
not provided Uncertain:1
Not observed at significant frequency in large population cohorts (gnomAD); 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 -
Dilated cardiomyopathy 1J Uncertain:1
This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 2 of the EYA4 protein (p.Glu2Gly). This variant is present in population databases (rs780081930, gnomAD 0.007%). 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: 534390). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -
Cardiovascular phenotype Uncertain:1
The p.E2G variant (also known as c.5A>G), located in coding exon 1 of the EYA4 gene, results from an A to G substitution at nucleotide position 5. The glutamic acid at codon 2 is replaced by glycine, an amino acid with similar properties. This amino acid position is conserved. 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. -
