Genes affected

EYA4 (HGNC:3522): (EYA transcriptional coactivator and phosphatase 4) This gene encodes a member of the eyes absent (EYA) family of proteins. The encoded protein may act as a transcriptional activator through its protein phosphatase activity, and it may be important for eye development, and for continued function of the mature organ of Corti. Mutations in this gene are associated with postlingual, progressive, autosomal dominant hearing loss at the deafness, autosomal dominant non-syndromic sensorineural 10 locus. The encoded protein is also a putative oncogene that mediates DNA repair, apoptosis, and innate immunity following DNA damage, cellular damage, and viral attack. Defects in this gene are also associated with dilated cardiomyopathy 1J. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2014]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP6: Variant 6-133462487-ATCT-A is Benign according to our data. Variant chr6-133462487-ATCT-A is described in ClinVar as [Likely_benign]. Clinvar id is 178670.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr6-133462487-ATCT-A is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0982 is higher than 0.05.

Variant summary: EYA4 c.580+14_580+16delTCT alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 4/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.02 in 251064 control chromosomes, predominantly at a frequency of 0.1 within the African or African-American subpopulation in the gnomAD database, including 90 homozygotes. The observed variant frequency within African or African-American control individuals in the gnomAD database is approximately 4000-folds over the estimated maximal expected allele frequency for a pathogenic variant in EYA4 causing Cardiomyopathy phenotype (2.5e-05), strongly suggesting that the variant is a benign polymorphism found primarily in populations of African or African-American origin. Co-occurrence with another likely pathogenic TTN variant (c.34782_34785delTTGT, p.C11595fsX9) has been reported in an internal sample, providing supporting evidence for a benign role. Two ClinVar submissions (evaluation after 2014) cite the variant as likely benign/benign. Based on the evidence outlined above, the variant was classified as benign. -
