Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4BA1

This summary comes from the ClinGen Evidence Repository: The p.Val5145Ile variant in USH2A has been identified in at least 5 individuals with Usher syndrome; however, in 3 individuals no variant on the second allele was identified and in two individuals, no information about the other allele was provided (PMIDs 28041643, 25999674, 20829743, 27353947, 23591405). Additionally, the p.Val5145Ile variant was identified in 2 alleles of 56 retinitis pigmentosa patients, however it is unclear in which one or two patients these alleles were found (PMID 20591486). The filtering allele frequency of the p.Val5145Ile variant in the USH2A gene is 0.7% for European (Finnish) chromosomes by gnomAD (201/25124 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). Additionally, computational prediction analysis using the metapredictor tool REVEL suggests that the variant may not impact the protein (BP4) .In summary, this variant meets criteria to be classified as benign based primarily on population frequency data and the absence of cases with biallelic variants.

Genes affected

USH2A (HGNC:12601): (usherin) This gene encodes a protein that contains laminin EGF motifs, a pentaxin domain, and many fibronectin type III motifs. The protein is found in the basement membrane, and may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIa and retinitis pigmentosa. Multiple transcript variants encoding different isoforms have been found for this gene.

Val5145Ile in exon 71 of USH2A: This variant has been identified in one individu al with Usher syndrome or nonsyndromic retinitis pigmentosa and two individuals with nonsyndromic retinitis pigmentosa (van Wijk - unpublished data, McGee 2010, Clark 2010). However, it was not noted if any of these individuals had a second USH2A variant. In addition, this variant has also been identified in one proban d with Fundus albipunctatus who was homozygous for a null mutation in another ge ne (Schatz 2010). It has also been identified by our laboratory in two probands who have other etiologies for their hearing loss. Furthermore, this variant is n ot expected to have clinical significance because it has been identified in 0.6% (48/8600) of European American chromosomes by the NHLBI Exome Sequencing Projec t (http://evs.gs.washington.edu/EVS/; dbSNP rs111033269). In summary, this varia nt meets our criteria to be classified as benign. -

Variant summary: USH2A c.15433G>A (p.Val5145Ile) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0031 in 251470 control chromosomes in the gnomAD database, including 4 homozygotes. Although reported in the literature, to our knowledge, no penetrant association of c.15433G>A in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Multiple clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and a majority consensus as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -

The filtering allele frequency of the p.Val5145Ile variant in the USH2A gene is 0.7% for European (Finnish) chromosomes by gnomAD (201/25124 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).
