Features of the course of the gestational process with the carriage of genotypes F5L:G(1961)A and F2:G(20210)A and inheritance options

Aim of the study – to establish the features of inheritance of the F5L:G(1961)A and F2:G(20210)A genotypes and to assess their influence on the course and outcomes of pregnancy.Materials and methods. The object of the study was 70 mother–child pairs: 50 women, carriers of the F5L:G(1961)A mutation, and their children; 20 female patients, carriers of the F2:G(20210)A mutation, their children. Additionally, 18 families of women, carriers of the factor V Leiden mutation, in three generations were studied.Results. Carriage of the F5:(1961)GA and F2:(20210)GA genotypes in fetuses is associated with the risk of developing gestational complications in their mothers, which are primarily realized when the maternal laboratory phenotype is manifested. A higher frequency of occurrence of the minor allele A20210 of the FII gene was determined in children than in the older generation (p = 0,0006).
