FOXP3 and psoriasis: For instance, a previous study in Hungarian population showed that the variant homozygote (AA) of rs3761548 was a protective factor against AR in female patients.9 However, the allele and genotype distributions of this SNP did not differ significantly between the male patients and controls.9 Gao et al investigated a Chinese Han population and reported that the variant genotype (CA+AA) of Foxp3 rs3761548 engendered the enhanced risk of psoriasis in male individuals.
