Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PM2_Supporting

This summary comes from the ClinGen Evidence Repository: The variant NM_206933.4:c.14419G>A in USH2A is a missense variant predicted to cause substitution of alanine by threonine at amino acid 4807 (p.Ala4807Thr). The filtering allele frequency (the upper threshold of the 95% CI of 5/30782) of the c.14419G>A variant in USH2A is 0.00006365 for South Asian chromosomes by gnomAD v2.1.1, which is lower than the ClinGen Hearing Loss VCEP threshold (<0.00007) for PM2_Supporting, and therefore meets this criterion (PM2_Supporting). In summary, the clinical significance of this variant is uncertain. ACMG/AMP criteria applied, as specified by the Hearing Loss Expert Panel: PM2_Supporting (ClinGen Hearing Loss VCEP specifications version 2; 2/21/2024).

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.
