Genes affected

RAPGEF5 (HGNC:16862): (Rap guanine nucleotide exchange factor 5) Members of the RAS (see HRAS; MIM 190020) subfamily of GTPases function in signal transduction as GTP/GDP-regulated switches that cycle between inactive GDP- and active GTP-bound states. Guanine nucleotide exchange factors (GEFs), such as RAPGEF5, serve as RAS activators by promoting acquisition of GTP to maintain the active GTP-bound state and are the key link between cell surface receptors and RAS activation (Rebhun et al., 2000 [PubMed 10934204]).[supplied by OMIM, Mar 2008]

The c.1063C>T (p.R355C) alteration is located in exon 14 (coding exon 11) of the RAPGEF5 gene. This alteration results from a C to T substitution at nucleotide position 1063, causing the arginine (R) at amino acid position 355 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
