Genes affected

VAV2 (HGNC:12658): (vav guanine nucleotide exchange factor 2) VAV2 is the second member of the VAV guanine nucleotide exchange factor family of oncogenes. Unlike VAV1, which is expressed exclusively in hematopoietic cells, VAV2 transcripts were found in most tissues. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

Ambry Genetics

Dec 16, 2023

The c.2587C>T (p.R863W) alteration is located in exon 29 (coding exon 29) of the VAV2 gene. This alteration results from a C to T substitution at nucleotide position 2587, causing the arginine (R) at amino acid position 863 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
