Popis: Association between the angiotensinogen gene (M235T) and pre-eclampsia has been confirmed in recent studies. Pre-eclampsia is a complication of pregnancy characterized by increased vascular resistance, higher blood pressure, proteinuria and oedema that appear in the second and third trimester of pregnancy. This study aimed at investigating the relationship between M235T gene polymorphism and pregnant women with different forms of pre-eclampsia. One hundred and fifteen pre-eclamptic women and 100 normal control group were recruited and evaluated for the frequency of M235T mutation using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). A positive association was found between maternal age over 35 years (OR= 6.67; CI: 2.09-23.59), previous family history of hypertension (OR= 3.01; CI: 1.18-7.66), previous pre-eclampsia (OR= 7.44; CI: 2.47-22.42), history of reproductive losses (OR= 53.98; CI: 3.23-90.88), fetal anomalies (OR= 8.4; CI: 1.06-180.33), and pre-eclampsia. The frequency of heterozygous carriers of M235T mutation in pre-eclampsia (19.1%) was higher than that in control (14%) but the difference was statistically non-significant. Also, the frequency of M235T mutation was higher in mild pre-eclampsia women (63.6%) compared to women with severe pre-eclampsia (36.4%), however this was statistically non-significant. This study revealed that the frequency of M235T mutation was higher within women with mild pre-eclampsia.
