One of the possible reasons for these sex-specific differences in the value of the BAG6 rs805303 G > A locus in the development of pathology with elevated BP may be the modifying effect on the phenotypic manifestation of this polymorphism of an unequal confounder factor list taken into account in these studies (BMI, TC, TG, HDL-C, LDL-C, blood glucose, smokers—present study; age, family history of PE, pre-pregnancy BMI, obesity, number of gravidities, spontaneous/induced abortions, stillbirths, smokers—previous study [104]). Here, BAG6 is linked to obesity due to melanocortin 4 receptor deficiency.
