Turner syndrome is a chromosomal disorder characterized by the total or partial loss of one of the sex chromosomes in the female gender. Therefore, the karyotype of these women will be 45.X0 instead of the normal karyotype which is 46.XX. It is not known whether the cause may be due to meiotic problems (formation of the oocytes in the mother) or mitotic problems (division of the cells in the embryo).
This is why women with Turner syndrome are more likely to have children with Turner syndrome or other genetic disorders, because the segregation of their chromosomes occurs in an unbalanced way.
