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.

Primary ciliary dyskinesia Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jul 25, 2022 | For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 406540). This variant has not been reported in the literature in individuals affected with RPGR-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln456*) in the RPGR gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RPGR are known to be pathogenic (PMID: 16055928, 16969763). - |
