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.649G>C (p.G217R) alteration is located in exon 6 (coding exon 6) of the RP9 gene. This alteration results from a G to C substitution at nucleotide position 649, causing the glycine (G) at amino acid position 217 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
