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]

TARID (HGNC:50506): (TCF21 antisense RNA inducing promoter demethylation)

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.33).
• BP6: Variant 6-133506135-C-T is Benign according to our data. Variant chr6-133506135-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 1753178.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-0.137 with no splicing effect.
• BS1: Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00000617 (9/1459520) while in subpopulation EAS AF = 0.000151 (6/39664). AF 95% confidence interval is 0.0000652. There are 0 homozygotes in GnomAdExome4. There are 3 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check.
• BS2: High AC in GnomAdExome4 at 9 AD gene.
