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.

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 10, 2015Variant classified as Uncertain Significance - Favor Benign. The p.Ile3030Thr va riant in USH2A has not been previously reported in individuals with hearing loss or Usher syndrome or in large population studies. Isoleucine (Ile) at position 3030 is not conserved in some mammals and many evolutionarily distant species, w ith 5 fish species having a threonine (Thr) at this position. Computational pred iction tools do not provide strong support for or against an impact to the prote in. In summary, while the clinical significance of the p.Ile3030Thr variant is u ncertain, the lack of evolutionarily conservation suggests that it is more likel y to be benign. -

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeOct 03, 2022This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 3030 of the USH2A protein (p.Ile3030Thr). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with USH2A-related conditions. ClinVar contains an entry for this variant (Variation ID: 229629). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt USH2A protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
