Genes affected

ICAM3 (HGNC:5346): (intercellular adhesion molecule 3) The protein encoded by this gene is a member of the intercellular adhesion molecule (ICAM) family. All ICAM proteins are type I transmembrane glycoproteins, contain 2-9 immunoglobulin-like C2-type domains, and bind to the leukocyte adhesion LFA-1 protein. This protein is constitutively and abundantly expressed by all leucocytes and may be the most important ligand for LFA-1 in the initiation of the immune response. It functions not only as an adhesion molecule, but also as a potent signalling molecule. Alternative splicing results in multiple transcript variants encoding different isoforms.

Collection Method: clinical testing

The c.1507G>T (p.V503L) alteration is located in exon 7 (coding exon 7) of the ICAM3 gene. This alteration results from a G to T substitution at nucleotide position 1507, causing the valine (V) at amino acid position 503 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
