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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 27, 2024The c.227G>A (p.R76Q) alteration is located in exon 2 (coding exon 2) of the ICAM1 gene. This alteration results from a G to A substitution at nucleotide position 227, causing the arginine (R) at amino acid position 76 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
