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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Retinitis pigmentosa 39 (MIM#613809) and Usher syndrome, type 2A (MIM#276901). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0200 - Variant is predicted to result in a missense amino acid change from serine to phenylalanine. (I) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD (v2) <0.01 for a recessive condition (21 heterozygotes, 0 homozygotes). (SP) 0502 - Missense variant with conflicting in silico predictions and uninformative conservation. (I) 0604 - Variant is not located in an established domain, motif, hotspot or informative constraint region. (I) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0809 - Previous evidence of pathogenicity for this variant is inconclusive. This variant has been reported in two patients with inherited retinal dystrophy (PMID: 32037395, 33623043) and both classified as VUS. It has also been reported as VUS and pathogenic in ClinVar. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 4111 of the USH2A protein (p.Ser4111Phe). This variant is present in population databases (rs142095945, gnomAD 0.02%). This missense change has been observed in individual(s) with clinical features of USH2A-related conditions ‚Äã (PMID: 30902645, 32037395; internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 48396). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt USH2A protein function with a negative predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -

Significance:Likely pathogenic

Review Status:no assertion criteria provided

Collection Method:clinical testing

The USH2A c.12332C>T variant is predicted to result in the amino acid substitution p.Ser4111Phe. This variant has been reported along with a second USH2A variant in individuals with retinitis pigmentosa (Table S2, Martin-Merida et al. 2019. PubMed ID: 30902645; Table S2, Zampaglione et al. 2020. PubMed ID: 32037395). This variant is reported in 0.015% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as likely pathogenic. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The Ser4111Phe vari ant in USH2A has not been reported in the literature; however, this variant has been identified by our laboratory in two other individual with hearing loss; nei ther of whom had a second USH2A variant. Computational analyses (biochemical ami no acid properties, homology, PolyPhen2, SIFT, AlignGVGD) do not provide strong support for or against pathogenicity. In summary, the clinical significance of t his variant cannot be determined with certainty at this time; however, based upo n this data we would lean towards a more likely benign interpretation. -
