The objective of the study is to assess NOS3 and ESR1 gene polymorphism in adolescent girls born with low birth weight (LBW) and suffered by anomalous uterine bleeding (AUB). A total 95 adolescent girls were studied including 32 born with LBW and AUB; 36 girls with normal birth weight and AUB; and 27 healthy girls. Single allele gene polymorphism NOS3 786T > C, 894G > T, ESR1 351A > G and 397T > C was studied. The existence of polymorphous allele С gene NOS3 786Т > С (for homozygote OR = 2.03; 95% CI: 1.12-3.68; p = 0.04; for heterozygote OR = 1.68; 95% CI: 1.09-2.60; p = 0.046) and genotype Pvull-CC ESR1 (OR = 4.58; 95% CI: 0.97-21.68; p = 0.04) was detected in LBW girls with AUB. It was suggested that intrauterine programming of endothelial dysfunction syndrome could play a significant role in the development of AUB in adolescent girls born with LBW.
