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]

Collection Method: clinical testing

The c.599A>C (p.H200P) alteration is located in exon 3 (coding exon 3) of the VCAM1 gene. This alteration results from a A to C substitution at nucleotide position 599, causing the histidine (H) at amino acid position 200 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
