Apolipoprotein E (APOE) gene variants have been reported to influence psoriasis risk. However, data is limited to a few ethnicities and no similar study has been performed in middle eastern populations. We investigated this association in Saudi psoriasis patients.<jats:italic>Methods<\/jats:italic>. Saudi subjects (294) were genotyped for APOE gene using APOE StripAssay kit.<jats:italic>Results<\/jats:italic>. The frequencies of alleles<jats:italic>\u03b5<\/jats:italic>2,<jats:italic>\u03b5<\/jats:italic>4, and genotypes<jats:italic>\u03b5<\/jats:italic>3\/<jats:italic>\u03b5<\/jats:italic>4 and<jats:italic>\u03b5<\/jats:italic>3\/<jats:italic>\u03b5<\/jats:italic>2 were significantly higher in psoriasis patients compared with those in controls. The frequency of<jats:italic>\u03b5<\/jats:italic>3 allele and<jats:italic>\u03b5<\/jats:italic>3\/<jats:italic>\u03b5<\/jats:italic>3 genotype was significantly lower in patients.

The serum cholesterol, triglycerides, and LDL levels were significantly higher in psoriasis patients contrary to HDL level. Patients with APOE<jats:italic>\u03b5<\/jats:italic>4 had significantly higher levels of total cholesterol and LDL cholesterol, whereas those with the<jats:italic>\u03b5<\/jats:italic>2 had higher HDL cholesterol, and triglycerides.<jats:italic>Conclusion<\/jats:italic>. APOE alleles<jats:italic>\u03b5<\/jats:italic>2,<jats:italic>\u03b5<\/jats:italic>4, and genotypes<jats:italic>\u03b5<\/jats:italic>2\/<jats:italic>\u03b5<\/jats:italic>3 and<jats:italic>\u03b5<\/jats:italic>4\/<jats:italic>\u03b5<\/jats:italic>3 are associated with psoriasis and can be a risk factor while allele<jats:italic>\u03b5<\/jats:italic>3 and genotype<jats:italic>\u03b5<\/jats:italic>3\/<jats:italic>\u03b5<\/jats:italic>3 may be protective for psoriasis in Saudis.
