Genes affected

VAV3 (HGNC:12659): (vav guanine nucleotide exchange factor 3) This gene is a member of the VAV gene family. The VAV proteins are guanine nucleotide exchange factors (GEFs) for Rho family GTPases that activate pathways leading to actin cytoskeletal rearrangements and transcriptional alterations. This gene product acts as a GEF preferentially for RhoG, RhoA, and to a lesser extent, RAC1, and it associates maximally with the nucleotide-free states of these GTPases. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jul 2008]

The c.2383G>A (p.A795T) alteration is located in exon 26 (coding exon 26) of the VAV3 gene. This alteration results from a G to A substitution at nucleotide position 2383, causing the alanine (A) at amino acid position 795 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
