RTEL1 and dysplastic nevus: Presence of dysplastic nevi was most strongly associated with the G allele of the SNP rs6011002 (OR = 3.30, 95% CI: 1.64, 6.61; P-trend = 7.75×10−4; Figures S3 and S4 and Tables S4 and S5), which is located in the regulator of telomere elongation helicase 1 (RTEL1) gene region.
