Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM3_StrongPM2PP4

This summary comes from the ClinGen Evidence Repository: The c.6446C>A (p.Pro2149Gln) variant in USH2A was absent from gnomAD (PM2). It has been detected in one patient with Usher syndrome and one patient with isolated Retinitis pigmentosa, both of whom carried another suspected pathogenic variant in trans (PM3_Strong; PP4; PMIDs: 26872967, 29074561, 28041643; ClinVar ID: 2356). In summary, this variant meets criteria to be classified as likely pathogenic for autosomal recessive Usher syndrome based on the ACMG/AMP criteria applied as specified by the Hearing Loss Expert Panel: PM2, PM3_Strong, PP4.

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.
