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]
LIMASI (HGNC:56357): (lncRNA inflammatory and mucous response associated, antisense to ICAM1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2023The c.224A>G (p.N75S) alteration is located in exon 2 (coding exon 2) of the ICAM1 gene. This alteration results from a A to G substitution at nucleotide position 224, causing the asparagine (N) at amino acid position 75 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
