Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BS1_SupportingBP2

This summary comes from the ClinGen Evidence Repository: The p.Leu1572Phe variant in USH2A gene has a filtering allele frequency= 0.12% in Latino in gnomAD (54/35388 with 95% CI) which is a higher frequency than would be expected for an autosomal recessive pathogenic variant based on the thresholds defined by the ClinGen Hearing Loss Expert Panel (BS1 supporting). It was reported in multiple publications as a polymorphism or as non-pathogenic based on detection among normal control chromosomes or other evidence (PMID:18273898, 19881469 and 17085681). Although the variant was reported in trans with c.2299delG in one patient diagnosed with Usher syndrome type II and in another with unclassified Usher syndrome (PMID:25097241 and 28944237), it was also identified in cis with c.2299delG; p.Glu767Serfs and in unknown configuration with c.2299delG and a stop codon (PMID:25472526), both in patients with Usher syndrome type II (BP2; PMID:20507924, 25097241, 17405132 and 26969326). Computational prediction using REVEL was 0.65 which did not meet the Hearing Loss Expert Panel (HL EP) specified threshold of >0.7 for PP3. In summary, this variant meets criteria to be classified as likely benign for autosomal recessive Usher syndrome, type 2A based on the HL EP-specified ACMG/AMP criteria applied (BS1, BP2).

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.

Computational prediction using REVEL was 0.65 which did not meet the Hearing Loss Expert Panel (HL EP) specified threshold of >0.7 for PP3. In summary, this variant meets criteria to be classified as likely benign for autosomal recessive Usher syndrome, type 2A based on the HL EP-specified ACMG/AMP criteria applied (BS1, BP2). -
