Genes affected

RAPGEF1 (HGNC:4568): (Rap guanine nucleotide exchange factor 1) This gene encodes a human guanine nucleotide exchange factor. It transduces signals from CRK by binding the SH3 domain of CRK, and activating several members of the Ras family of GTPases. This signaling cascade that may be involved in apoptosis, integrin-mediated signal transduction, and cell transformation. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some variants has not been determined. [provided by RefSeq, Jul 2008]

The c.2123C>T (p.P708L) alteration is located in exon 14 (coding exon 14) of the RAPGEF1 gene. This alteration results from a C to T substitution at nucleotide position 2123, causing the proline (P) at amino acid position 708 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
