Genetic Variant VAV2:p.Arg863Gly (chr9-133768444-G-C) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PP3_ModerateBS2

The NM_001134398.2(VAV2):c.2587C>G(p.Arg863Gly) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.00000411 in 1,460,554 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R863W) has been classified as Uncertain significance.

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]
