Turners Syndrome. Turner syndrome is caused in females when there is absence of one xchromosime, the girls are born with one x chromosome and the features are. Short stature, broad chest, low hairline, low set ears and webbed neck. There is non functioning ovaries and they do not get menstruation. They are more prone to congenital heartdisease, hypothyriodism, diabetes and few other conditions.
Turner. Its a genetic disorder caused by a chromosome abnormality. One x chromosome is missing in some or all cells. It manifests in the classic case as a female with short stature, webbed neck, wide spaced nipples, shield-shaped chest, short fingers, cardiac and kidney problems, GI issues, endocrine problems with growth, thyroid, diabetes, autoimmune disorders.
Lack of chromosome. Normal humans have 22 pairs of regular chromosomes (chms) and one pair of sex chms. At conception you are supposed to get one of each pair from each parent. If one of the sex (X) chms is lost from the egg, the fetus (which can survive the mistake) will be born with 22 pr of regular chms and only one X.The defect occurs in the formation of the egg. The effect on the kid varies.
See below. Turner syndrome is a genetic condition in which a female does not have the usual pair of two x chromosomes. Those with turner syndrome can have a normal life when carefully monitored by their doctor. There is no known way to prevent turner syndrome.
45 X/0 Pattern. At conception, one half of a set of 46 (23pairs) chromosomes (cms) is brought from egg & sperm. If the combination is missing one x of the sex cms, a girl is born with 45 instead of 46 cms. The loss can affect every cell in the body, resulting in a variety of heart, kidney, brain or other problems. It also may cause no specific problem & not be noticed until late childhood. Supportive care is needed.
What causes turner syndrome, noonan syndrome, & the rare klippel-fell syndrome? What happens during fetal development that causes these conditions?
A genetic accident. During formation of the egg or sperm can leave out an x chromosome in either one. A fetus whose genetic make-up includes the germ cell missing a chr. X has turner syndrome. One of 8 different genetic mutations is passed on to a fetus by 1 parent or happens spontaneously to cause noonan syndrome. 2 related genetic mutations are passed on to the fetus by 1 parent to cause klippel-feil syndrome.
Turner's Syndrome. The prognosis for turner's syndrome diagnosed at birth is usually good. They will be short. They have streaked gonads. They can have a webbed neck. There can be lymphedema. There can be associated perceptual problems. They are not necessarily mentally retarded. There can be coarctation of the aorta.
Good with monitoring. Turner syndrome (ts) results from a problem with the chromosomes and so there is no cure. However, the prognosis for ts can be good, with careful health monitoring and early treatment of problems that can occur. Many women with turner syndrome lead full and active lives and can expect a normal lifespan. Visit www. Turnersyndrome. Org for more info.
45 X/0 Pattern. At conception, one half of a set of 46 (23pairs) chromosomes (cms) is brought from egg & sperm. If the combination is missing one x of the sex cms, a female is born with 45 instead of 46 cms, to reflect the loss. The lost cms can effect every cell in the body, resulting in a variety of heart, kidney, brain or other problems. It also may cause no specific problem & not be noticed until lat childhood.
Compressed iliac vei. May- thurner syndrome classically refer to a compression of the left common iliac vein by the iliac artery. This result in left leg pain, swelling and deep vein thrombosis. It has now been expanded and is now called non thrombotic iliac vein lesions (nivl), to include both the right and left iliac veins.).
I looked it up. This syndrome can begin with severe shoulder or arm pain followed by weakness and numbness[Those who suffer from Parsonage–Turner experience acute, sudden-onset pain radiating from the shoulder to the upper arm. Affected muscles become weak and atrophied. This is from Wikipedia - I had never heard of it.
Two cell lines. Regular turner syndrome arises when the drop out of one "x" sex chromosome occurs before or at conception, then all babies cells would have xo turner. When it drops out after conception, after the first, second or whatever cell division, a line of xo affects that cell line but normal xx are in the other cells. Mosaics have less turner specific abnormalities but effect varies on % of affected cells.
Partial. Turner syndrome occurs when a girl only has one x chromosome. Mosaic turner syndrome occurs when some of the cells in a girl have two x chromosomes and the rest have one x chromosome. Women with mosaic turner syndrome can have all of the same problems as women with turner syndrome, but the severity tends to be milder. Short stature, sterility, heart disease, and learning problems can all occur.
Nerve pain syndrome. This is an uncommon nerve pain/dysfunction syndrome that usually begins with shoulder pain on one side and neurologic changes of reflexes and weakness involving the involved muscles of the arm. It's causes include viral infections and vaccinations. Treatment helps and fulkl recovery within 3 yrs occurs in ~90%. Seewww. Ncbi. Nlm. Nih. Gov/pcm/articles/pmc2926354.
