Genes affected
ICAM4 (HGNC:5347): (intercellular adhesion molecule 4 (Landsteiner-Wiener blood group)) This gene encodes the Landsteiner-Wiener (LW) blood group antigen(s) that belongs to the immunoglobulin (Ig) superfamily, and that shares similarity with the intercellular adhesion molecule (ICAM) protein family. This ICAM protein contains 2 Ig-like C2-type domains and binds to the leukocyte adhesion LFA-1 protein. The molecular basis of the LW(A)/LW(B) blood group antigens is a single aa variation at position 100; Gln-100=LW(A) and Arg-100=LW(B). Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]
ICAM4-AS1 (HGNC:55990): (ICAM4 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 01, 2022The c.374C>T (p.T125I) alteration is located in exon 1 (coding exon 1) of the ICAM4 gene. This alteration results from a C to T substitution at nucleotide position 374, causing the threonine (T) at amino acid position 125 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
