Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BA1BP3

This summary comes from the ClinGen Evidence Repository: NM_001034853.2(RPGR):c.2606_2620del (p.Glu869_Glu873del) is a short in-frame deletion of 15 nucleotides that encode amino acids 869–873 within a low-complexity region (PMID:27162334) that extends approximately from amino acids 787–1043 in RPGR (BP3). This variant is present in gnomAD v4.1.0 at a frequency of 0.007397 among hemizygous individuals, with 1,400 variant alleles / 189,256 total alleles, which is higher than the ClinGen X-linked IRD VCEP BA1 threshold of >0.00005 (BA1). In summary, this variant is classified as benign 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; BA1 and BP3. (date of approval 05/16/2025). LINK:https://erepo.genome.network/evrepo/ui/classification/CA10385260/MONDO:0100437/106

Genes affected
RPGR (HGNC:10295): (retinitis pigmentosa GTPase regulator) This gene encodes a protein with a series of six RCC1-like domains (RLDs), characteristic of the highly conserved guanine nucleotide exchange factors. The encoded protein is found in the Golgi body and interacts with RPGRIP1. This protein localizes to the outer segment of rod photoreceptors and is essential for their viability. Mutations in this gene have been associated with X-linked retinitis pigmentosa (XLRP). Multiple alternatively spliced transcript variants that encode different isoforms of this gene have been reported, but the full-length natures of only some have been determined.
