Can you have a child with Turner syndrome?
Sometimes, it’s because of a problem with the sperm or the egg, and other times, the loss or alteration of the X chromosome happens early in fetal development. Family history doesn’t seem to be a risk factor, so it’s unlikely that parents of one child with Turner syndrome will have another child with the disorder.
Does Turner syndrome make you 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.
What causes mosaic Turner syndrome?
The cause is a missing or incomplete X chromosome (the chromosome that determines a person’s sex before birth). The missing gene prevents the body from growing and developing normally. TS affects only women and girls and affects every woman or girl differently.
Why does Turner syndrome only affect females?
The condition only occurs in females. Most commonly, a female with Turner syndrome has only 1 X chromosome. Others may have 2 X chromosomes, but one of them is incomplete. Sometimes, a female has some cells with 2 X chromosomes, but other cells have only 1.
Can Turner syndrome be prevented?
You can’t prevent Turner syndrome. It’s a congenital problem. It happens when a random error results in a missing or incomplete X chromosome.
What is the difference between Turner syndrome and mosaic Turner syndrome?
In classical Turner syndrome, an X chromosome is completely missing. This affects about half of all people with TS. Mosaic Turner syndrome, mosaicism, or Turner mosaicism is where the abnormalities occur only in the X chromosome of some of the body’s cells.
Can Turner syndrome be detected before birth?
Turner syndrome is usually identified during childhood or at puberty. However, it can sometimes be diagnosed before a baby is born using a test called amniocentesis.
What is the lifespan of someone with Turner syndrome?
What is the long-term outlook for people with Turner syndrome? The long-term outlook ( prognosis ) for people with Turner syndrome is typically good. Life expectancy is slightly shorter than average but may be improved by addressing and treating associated chronic illnesses, such as obesity and hypertension .
What percentage of Turner syndrome is Mosaic?
The published prevalence of Turner syndrome is 40/100,000, but only 60% of those Turner syndrome cases are caused by 45,X or 45,X/46,XX mosaicism, the rest being due to other abnormalities such as deletions or isoXq,15,16 thus the prevalence of aneuploidy causing Turner syndrome is around 24/100,000.
What genetic error causes Turner syndrome?
Turner syndrome is caused by partial or complete loss (monosomy) of the second sex chromosome. Chromosomes are found in the nucleus of all body cells. They carry the genetic characteristics of each individual and they come in pairs.
Can you live a normal life with Turner syndrome?
Despite these physical differences and other problems, with the right medical care, early intervention, and ongoing support, a girl with Turner syndrome can lead a normal, healthy, and productive life.
