1297C/T polymorphism of CYP4F2 gene was studied in 108 patients with chronic liver diseases. No significant correlation with predisposition to rapid liver cirrhosis was revealed without consideration for cirrhosis etiology (OR = 0.93, 95% CI = 0.28-2.99, p = 0.885). In patients with viral cirrhosis, a tendency to association of 1297T allele genotypes with rapid cirrhosis development was found (OR = 6.0, 95% CI = 0.28-382.64, p = 0.222). At the same time, CYP4F2 1297T allele was associated with mild (Child–Pugh class A-B) cirrhosis (OR = 2.9, p = 0.044).
