Possible association between actinic keratosis and the rs7208422 (c.917A→T, p.N306l) polymorphism of the EVER2 gene in patients without epidermodysplasia verruciformis.

Mutations of the EVER1 and EVER2 genes cause epidermodysplasia verruciformis (EV), a genodermatosis associated with squamous cell carcinoma (SCC). Recently, it has been found that the rs7208422 (c.917A→T, p.N306l) polymorphism in the EVER2 gene is related to an increased risk of SCC in patients with conditions other than EV. We hypothesized that this polymorphism might be also associated with actinic keratoses (AK). To determine whether the rs7208422 polymorphism of the EVER2 gene is associated with AK in non-EV patients. We genotyped rs7208422 in 65 patients with AK and 274 controls, using reverse transcription PCR. We detected a trend towards an association between AK and the TT genotype of rs7208422; the frequency of this genotype was 38.5% in patients with AK and 26.3% in controls (OR xa0=xa0 1.75, P xa0xa03 body areas (ORxa0=xa03.14, Pxa0=xa00.03 for the recessive model; ORxa0=xa02.34, Pxa0=xa00.01 for allelic comparison). These associations remained significant in a multivariate regression analysis, showing that both parameters were independently associated with the TT genotype (Pxa0=xa00.031). This study indicates a potential role of the rs7208422 (c.917A→T, P.N306l) polymorphism of the EVER2 gene in AK.
