Variant summary
Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP4BP6BS1BS2
The NM_004100.5(EYA4):c.103C>G(p.Leu35Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000818 in 1,613,628 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 Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. L35L) has been classified as Likely benign.

Dilated cardiomyopathy 1J Uncertain:1
This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 35 of the EYA4 protein (p.Leu35Val). This variant is present in population databases (rs35562371, gnomAD 0.008%). 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: 839376). 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.L35V variant (also known as c.103C>G), located in coding exon 3 of the EYA4 gene, results from a C to G substitution at nucleotide position 103. The leucine at codon 35 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
not specified Benign:1
Variant summary: EYA4 c.103C>G (p.Leu35Val) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-05 in 251396 control chromosomes. The observed variant frequency is approximately 3 fold of the estimated maximal expected allele frequency for a pathogenic variant in EYA4 causing Dilated Cardiomyopathy phenotype (1.6e-05), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.103C>G in individuals affected with Dilated Cardiomyopathy and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. One laboratory classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as likely benign. -
