X-linked Inherited Retinal Disease VCEP

NM_001034853.2(RPGR):c.1747G>T (p.Glu583Ter) is a nonsense variant introducing a premature stop in codon 583 within exon 14 of 15, which is predicted to disrupt a critical C-terminal region required for proper glutamylation of RPGR (PVS1, PMID: 36445968). This variant is absent from gnomAD v4.1.0 (PM2_Supporting). This variant has been reported in at least 1 proband meeting one of the PS4 requirements of some functional vision impairment in affected males by age 30 years, and/or decreased or absent electroretinogram responses (PMID: 14564670, PMID: 17325176). However, the PS4_Supporting code requires at least 2 unrelated probands, so this criterion was not met. In summary, this variant is classified as likely pathogenic for RPGR-related retinopathy based on the ClinGen X-linked Inherited Retinal Disease Expert Panel Specifications to the ACMG/AMP Variant Interpretation Guidelines for RPGR Version 1.0.0; PVS1 and PM2_Supporting.

PM2_Supporting

This variant is absent from gnomAD v4.1.0 (PM2_Supporting).

PVS1

This is a nonsense variant that introduces a premature stop codon in exon 14 of 15 that is predicted to disrupt a critical C-terminal region required for proper glutamylation of RPGR (PVS1, PMID: 36445968).

PS4

This variant has been reported in at least 1 proband meeting one of the PS4 requirements of some functional vision impairment in affected males by age 30, and/or decreased or absent cone and/or rod ERG responses (PMID: 14564670, PMID: 17325176). However, the PS4_Supporting code requires at least 2 unrelated probands, so this criterion was not met.
