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

May 21, 2024

The c.1905A>C (p.Q635H) alteration is located in exon 23 (coding exon 23) of the VAV2 gene. This alteration results from a A to C substitution at nucleotide position 1905, causing the glutamine (Q) at amino acid position 635 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
