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]

The c.797A>C (p.N266T) alteration is located in exon 4 (coding exon 4) of the VCAM1 gene. This alteration results from a A to C substitution at nucleotide position 797, causing the asparagine (N) at amino acid position 266 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
