Genes affected
RP2 (HGNC:10274): (RP2 activator of ARL3 GTPase) The RP2 locus has been implicated as one cause of X-linked retinitis pigmentosa. The predicted gene product shows homology with human cofactor C, a protein involved in the ultimate step of beta-tubulin folding. Progressive retinal degeneration may therefore be due to the accumulation of incorrectly-folded photoreceptor or neuron-specific tubulin isoforms followed by progressive cell death [provided by RefSeq, Jul 2008]

Submissions by phenotype
not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 28, 2021 | For these reasons, this variant has been classified as Pathogenic. Disruption of the initiator codon has been observed in individuals with RP2-related conditions (PMID: 26355662, 29847639; Invitae). This variant is not present in population databases (ExAC no frequency). This sequence change affects the initiator methionine of the RP2 mRNA. The next in-frame methionine is located at codon 41. - |
