The 31-year-old woman from Khimki near Moscow was born the third double in a row. All mothers of large families, now seven children.
About the unusual case of one family of three pairs of twins said the Commissioner for children’s rights in Moscow region Ksenia Mironova. A resident of the suburban town of Khimki (in the photo) gave birth to two twins, a boy and a girl. Prior to that, she twice in a row also gave birth to twins and became the mother of one child.
According to Xenia Mironovoj, all generations of this woman took place in Khimki hospital: first, her daughter was born, and then “every couple years” three times born twins.
Scientists assume that there exists an inherited genetic predisposition to having twins. For example, the study of genetics from the UK has shown that multiple pregnancy may be associated with the protein IGF-1 (insulin-like growth factor 1), which is encoded by the IGF1 gene. This protein is involved in the regulation of growth, development and differentiation of cells and tissues of the body. In addition, IGF-1 stimulates in women the production of eggs, which contributes to multiple pregnancies.
