The prediction of IL-10 gene each polymorphism for PCa risk was explored by comparing mutant allele with wild allele (termed the allele model), heterozygous genotype with wild genotype (termed the hetero-genotype model), homozygote genotype with wild genotype (termed the homo-genotype model) and combined heterozygote/homozygous genotypes with wild genotype (termed the dominant model), respectively. This evidence concerns the gene IL10 and posterior cortical atrophy.
