Genes affected

VCAM1 (HGNC:12663): (vascular cell adhesion molecule 1) This gene is a member of the Ig superfamily and encodes a cell surface sialoglycoprotein expressed by cytokine-activated endothelium. This type I membrane protein mediates leukocyte-endothelial cell adhesion and signal transduction, and may play a role in the development of artherosclerosis and rheumatoid arthritis. Three alternatively spliced transcripts encoding different isoforms have been described for this gene. [provided by RefSeq, Dec 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.34118968).

The c.718G>T (p.G240C) alteration is located in exon 4 (coding exon 4) of the VCAM1 gene. This alteration results from a G to T substitution at nucleotide position 718, causing the glycine (G) at amino acid position 240 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
