ClinGen Hearing Loss Variant Curation Expert Panel	RCV001775076	SCV000927009	benign	Usher syndrome	2020-12-24	reviewed by expert panel	curation	The p.Ser841Tyr variant in the USH2A gene has been identified in three individuals with Usher syndrome (PMIDs 19683999, 28944237, 28653555); however, in two of those individuals a variant on the second allele was not identified (PMIDs 19683999, 28944237) and in one (PMID 28653555), the variant found on the other alleles (p.Tyr1992Cys) did not have evidence to support pathogenicity and has a high allele frequency in gnomAD (of European (Finnish) chromosomes). The filtering allele frequency of the p.Ser841Tyr variant in the USH2A gene is 1.4% for European (Finnish) chromosomes by gnomAD (1144/128242 with 95% CI), which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen Hearing Loss Expert Panel for autosomal recessive hearing loss variants (BA1).

A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Three of four in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0061 in 250428 control chromosomes, including 9 homozygotes. This frequency is not higher than the estimated maximum expected (MPAF) for a pathogenic variant in USH2A causing Usher Syndrome (0.011), however the presence of homozygotes suggests a benign role for the variant. In addition, the variant is reported in certain subpopulations with even higher frequencies, e.g. in the Finnish (0.016) and Swedish (0.015), which are above the MPAF, indicating that the variant is benign. Although the variant, c.2522C>A, has been reported to be found in individuals affected with Usher Syndrome related phenotypes (HGMD), the Deafness Variation Database (DVD), classified the variant as benign, based on ethnic-specific minor allele frequencies (Shearer_2014, Azaiez_2018). To our knowledge no experimental evidence demonstrating the variant impact on protein function have been reported. 12 submitters, including an expert panel (ClinGen Hearing Loss Variant Curation Expert Panel), have provided clinical-significance assessments for this variant in ClinVar after 2014, and classified the variant as likely pathogenic (n=1), VUS (n=4), likely benign (n=2) / benign (n=5; including the expert panel). Based on the evidence outlined above, the variant was classified as benign.
