While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 222 amino acid(s) of the RPGR (ORF15) protein. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with retinitis pigmentosa (PMID: 21857984, 31953110). This variant is also known as ORF15+1038delG (ORF15E346R158). ClinVar contains an entry for this variant (Variation ID: 2138534). This variant disrupts a region of the RPGR (ORF15) protein in which other variant(s) (p.Leu1130Lysfs13) have been determined to be pathogenic (PMID: 22264887; Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. (less)

Comment:

This sequence change creates a premature translational stop signal (p.Glu931Argfs*158) in the RPGR (ORF15) gene.
