Genes affected

RP9 (HGNC:10288): (RP9 pre-mRNA splicing factor) The protein encoded by this gene can be bound and phosphorylated by the protooncogene PIM1 product, a serine/threonine protein kinase . This protein localizes in nuclear speckles containing the splicing factors, and has a role in pre-mRNA splicing. CBF1-interacting protein (CIR), a corepressor of CBF1, can also bind to this protein and effects alternative splicing. Mutations in this gene result in autosomal dominant retinitis pigmentosa-9. This gene has a pseudogene (GeneID: 441212), which is located in tandem array approximately 166 kb distal to this gene. [provided by RefSeq, Sep 2009]

The c.484_485del variant is not present in publicly available population databases like 1000 Genomes, EVS, ExAC, Indian Exome Database or our in-house exome database. The variant is present in gnomAD, at a low frequency. This variant has neither been published in the literature in individuals affected with RP9-related conditions nor reported to clinical databases like ClinVar, Human Gene Mutation Database (HGMD) or OMIM in any affected individuals. In-silico pathogenicity prediction programs like MutationTaster2, CADD, Varsome, Franklin etc. predicted these variants to be likely deleterious. This variant causes frameshift at the 162nd amino acid position of the wild-type transcript, which creates a premature translational stop-signal at the altered transcript that may either result in translation of a truncated protein or cause nonsense-mediated decay of the mRNA. -
