Upon comparison of allelic frequencies (Table 2) with P < 0.05 (two-sided) and frequency of the IFNL3 rs12971396 C-allele of 88% in the non-dyslipidemia group and 96% in the dyslipidemia group, the power to detect an association between rs12971396 polymorphism and dyslipidemia reached 91.5%. The gene discussed is IFNL3; the disease is metabolic syndrome.
