Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.

What mutation causes Turner's syndrome?
In females who have Turner syndrome, one copy of the X chromosome is missing, partially missing or changed. The genetic changes of Turner syndrome may be one of the following: Monosomy. The complete absence of an X chromosome generally occurs because of an error in the father's sperm or in the mother's egg.
Is Turner syndrome caused by mother or father?
Turner syndrome is not caused by anything the parents did or did not do. The disorder is a random error in cell division that happens when a parent's reproductive cells are being formed. Girls born with the X condition in only some of their cells have mosaic Turner syndrome.
Is Turner syndrome caused by sperm or by egg?
In females who have Turner syndrome, one copy of the X chromosome is missing, partially missing or changed. The genetic changes of Turner syndrome may be one of the following: Monosomy. The complete absence of an X chromosome generally occurs because of an error in the father's sperm or in the mother's egg.
What Is Turner Syndrome? (Healthsketch)
Do Turner syndrome have eggs?
Nearly every girl born with Turner syndrome faces infertility due to rapid loss of egg reserve. Girls with complete Turner syndrome may lose all of their existing eggs in early childhood and even before reaching puberty.
Are Turner females fertile?
Most women with Turner's syndrome have ovarian dysgenesis; therefore, they are usually infertile, and in very rare cases have spontaneous menses followed by early menopause. Only 2% of the women have natural pregnancies, with high rates of miscarriages, stillbirths and malformed babies.
Does Turner syndrome run in families?
Turner syndrome is not usually inherited in families. Turner syndrome occurs when one of the two X chromosomes normally found in women is missing or incomplete. Although the exact cause of Turner syndrome is not known, it appears to occur as a result of a random error during the formation of either the eggs or sperm.
Turner Syndrome 101
Is Turner syndrome caused by deletion?
Turner syndrome (TS) is a chromosomal condition affecting 1 in 2000 females characterized by partial or complete deletion of one of the X chromosomes [1].
Are people with Turner's syndrome infertile?
Women with Turner syndrome are at extremely high risk for primary ovarian insufficiency (POI) and infertility. Although about 70–80% have no spontaneous pubertal development and 90% experience primary amenorrhea, the remainder may possess a small residual of ovarian follicles at birth or early childhood.

Is female with Turner syndrome is fertile?
Most women with Turner's syndrome have ovarian dysgenesis; therefore, they are usually infertile, and in very rare cases have spontaneous menses followed by early menopause. Only 2% of the women have natural pregnancies, with high rates of miscarriages, stillbirths and malformed babies.
Is Turner syndrome a trisomy or monosomy?
Monosomy X, or Turner syndrome, occurs when a baby is born with only one X sex chromosome, rather than the usual pair (either two Xs or one X and one Y sex chromosome).
