APOE and hyperuricemia: In the current study, we also compared other metabolic indicators that connected lipid metabolism with renal functions between different ApoE genotypes in hyperuricemia patients and controls and found both groups of subjects with the ApoE2 allele had a lower LDL-C level than those with the ApoE3 allele and ApoE4 allele, while the subjects with the ApoE4 allele had the highest LDL-C level than other groups, which was consistent with other studies [6].
