Genes affected

ICAM1 (HGNC:5344): (intercellular adhesion molecule 1) This gene encodes a cell surface glycoprotein which is typically expressed on endothelial cells and cells of the immune system. It binds to integrins of type CD11a / CD18, or CD11b / CD18 and is also exploited by Rhinovirus as a receptor. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.454C>T (p.R152C) alteration is located in exon 3 (coding exon 3) of the ICAM1 gene. This alteration results from a C to T substitution at nucleotide position 454, causing the arginine (R) at amino acid position 152 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
