Evidence submitted by expert panel
Leber Congenital Amaurosis/early onset Retinal Dystrophy VCEP
NM_000180.4(GUCY2D):c.2766C>G (p.Tyr922Ter) is a nonsense variant that introduces a premature stop codon into exon 15 of 20, and is predicted to lead to nonsense-mediated decay in a gene in which loss-of-function is an established mechanism of disease (PVS1). This variant is absent from gnomAD v4.1.0 (PM2_Supporting). This variant has been reported in at least 1 proband with early-onset severe retinal dystrophy who was homozygous for the variant (0.5 points, VCEP member-provided data, PM3_Supporting). In summary, this variant meets the criteria to be classified as pathogenic for GUCY2D-related recessive retinopathy based on the ACMG/AMP criteria applied, as specified by the ClinGen LCA/eoRD VCEP: PVS1, PM2_Supporting, and PM3_Supporting. (VCEP specifications version 1.0.0; date of approval 01/22/2025).
Met criteria codes
PVS1
This is a nonsense variant that introduces a premature stop codon into exon 15 of 20, and is predicted to lead to nonsense-mediated decay in a gene in which loss-of-function is an established mechanism of disease (PVS1).
PM3_Supporting
This variant has been reported in at least 1 proband with early-onset severe retinal dystrophy who was homozygous for the variant (0.5 points, VCEP member-provided data, PM3_Supporting).
PM2_Supporting
This variant is absent from gnomAD v4.1.0 (PM2_Supporting).
