Markers suggestive of association with skin-related clinical criteria. “Conditioned on …” = results from conditional logistic regression performed conditioning on the indicated SNP, MA: minor allele, “Case” and “Cont”: allele frequency of the minor allele in cases and controls respectively, OR: odds ratio, 95% CI = 95% confidence interval of the odds ratio, : value, AA: African-American ancestry, EA: European ancestry, Female −: female subjects lacking the indicated skin phenotype, Female +: female subjects with the indicated skin phenotype, Male −: males lacking the indicated skin phenotype, Male +: males with the indicated skin phenotype, Female ORs: odds ratio comparing female patients with and without the indicated skin phenotype, and Male OR: odds ratio comparing male patients with and without the indicated skin phenotype.
