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.

The c.1355T>C (p.V452A) alteration is located in exon 6 (coding exon 6) of the ICAM3 gene. This alteration results from a T to C substitution at nucleotide position 1355, causing the valine (V) at amino acid position 452 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
