Abstract

Genetic polymorphisms in leukocyte and endothelial cell adhesion molecules may be important variables with regard to susceptibility to multifactorial disease processes that include an inflammatory component. For this reason, polymorphisms were sought for intercellular adhesion molecule-1 (ICAM-1; gene symbol ICAM1) and for the three genes in the selectin cluster, P-selectin, L-selectin, and E-selectin (gene symbols SELP, SELL, and SELE, respectively). Two amino acid polymorphisms were identified for ICAM-1; Gly or Arg at codon 241 and Lys or Glu at codon 469. Dinucleotide repeat polymorphisms were identified in the 3′-untranslated region for ICAM-1 and in intron 9 for P-selectin. Restriction fragment length polymorphisms were found using cDNAs for each of the three selectin genes as probes; E-selectin with BglII, P-selectin with ScaI, and L-selectin with HincII. Linkage analysis was performed for the selectin gene cluster and for ICAM-1 using the CEPH families; ICAM-1 is very tightly linked to the LDL receptor on chromosome 19, and the selectin cluster is linked to markers at chromosome 1q23.
