Variant summary
Our verdict is Benign. Variant got -9 ACMG points: 2P and 11B. PM5BP4_ModerateBP6BS1BS2
The NM_000503.6(EYA1):c.1460C>T(p.Ser487Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00124 in 1,614,036 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S487P) has been classified as Pathogenic.

Otofaciocervical syndrome 1 Benign:2
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

EYA1-related disorder Uncertain:1
The EYA1 c.1460C>T variant is predicted to result in the amino acid substitution p.Ser487Leu. This variant has been reported in at least one individual with branchiootorenal (BOR) syndrome (referred to as c.1361T>C, p.Ser454Leu, Chang et al. 2004. PubMed ID: 15146463) and another individual with progressive hearing loss (Table S13, Neveling et al. 2013. PubMed ID: 24123792). It has been interpreted as non-pathogenic for congenital anomalies of the kidney and urinary tract (CAKUT, Table S2, Hwang et al. 2014. PubMed ID: 24429398;) and uncertain significance for BOR syndrome (Table S5, Nicolaou et al. 2016. PubMed ID: 26489027). This variant has been reported 212 times among ~283,000 alleles (~0.08%) in a large population database (https://gnomad.broadinstitute.org/variant/chr8-72127864-G-A), and has conflicting interpretations of likely benign and uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/228678/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Branchiootic syndrome 1 Benign:1
This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
not specified Benign:1
The p.Ser487Leu variant in EYA1 is classified as likely benign because it is present in 0.13% (177/129002) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant has been reported in 1 individual with Branchio-oto-renal syndrome, 2 individuals with hearing loss, and 4 individuals with vesicouretal reflux/CAKUT (Chang 2004, Neveling 2013, Hwang 2014, Nicolaou 2016). It has also been identified in 1 individual with ear abnormalities and hypoplastic kidneys who also had a 2q23 microdeletion and a de novo pathogenic variant in the CHD7 gene; the p.Ser487Leu variant segregated in the father with branchial cyst and duplication of renal collecting system (Badilla-Porras 2012). This variant has been reported by our laboratory in 2 unrelated Caucasian individuals with sensorineural hearing loss due to alternate genetic etiologies as well as in an unaffected parent. In summary, the frequency data and identification of this variant in individuals with an alternate genetic etiology and unaffected parent support a likely benign classification, despite the reports in the literature.
