Abstract

The loss of three or more subsequent pregnancies before the end of the 22nd week is observed in 0.4-1% of women. Despite great advances in medicine, the causes of pregnancy failure (miscarriages, missed abortions and stillbirths), and the birth of a child or children with congenital abnormalities, are still not determined precisely The purpose of the research was to determine the association of polymorphisms and mutations of coagulation factors II and V genes, as well as methylenetethrahydrofolate reductase (MTHFR) gene polymorphism, with the course of pregnancy and the type of reproductive failure. The research was performed in a group of 116 women referred to the Genetic Outpatient Clinic of the NCU SM in Bydgoszcz between 2009-2010 due to reproductive failures. The molecular tests for thrombophilia, i.e. mutation of the factor V Leiden, prothrombin gene mutation 20210G>A, and MTHFR polymorphism 677C>T were done in all patients. The Leiden mutation was found in 8 women (homozygotic in 2 of them) and prothrombin gene mutation in 3.85 women had the heterozygotic MTHFR polymorphism, while 24 the homozygotic one. Coexistence of the Leiden mutation and the MTHFR polymorphism was found in 3 patients with history of miscarriages. 1....Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
