High risk of cutaneous melanoma amongst carriers of the intercellular adhesion molecule-1 R241 allele.

We examined the relation between cutaneous melanoma risk and the intercellular adhesion molecule-1 (ICAM-1) gene single nucleotide polymorphisms G241R and K469E, as well as the circulating soluble form of ICAM-1 determined in plasma, in the population of Modena Province, northern Italy. Individuals carrying at least one R241 allele, versus those carrying the wild-type GG genotype, had a relative risk of melanoma of 4.3 (P = 0.022), whereas the K469E polymorphism was unrelated to disease risk. Soluble ICAM-1 levels above 10 ng/ml directly and strongly correlated with melanoma risk. In this population, individuals carrying the R241 allele of the ICAM-1 gene appeared to show an enhanced susceptibility to cutaneous melanoma, possibly because of increased ICAM-1 expression.
