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.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.52).
• BP6: Variant 1-215779946-G-T is Benign according to our data. Variant chr1-215779946-G-T is described in ClinVar as [Benign]. Clinvar id is 48359.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-215779946-G-T is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.092 is higher than 0.05.
