Klinefelter's Syndrome

Fitness (in Darwinian terms).

No it is caused by the Non-Disjunction of sex Chromosomes. Males with Klinefelter's syndrome have an extra X chromosome.

It most commonly affects males who are born to women over the age of 35.

Klinefelter syndrome is most often diagnosed in adulthood using a karyotype, an analysis of the patient's chromosomes taken from a blood sample. Klinefelter syndrome may also be diagnosed during a woman's pregnancy. Doctors can look for the chromosome abnormality in cells taken from the amniotic fluid that surrounds the fetus (amniocentesis), or from the placenta (chorionic villus sampling (CVS)).

A child with Klinefelter syndrome does not usually have any prominent features. Any physical characteristics are subtle. They may have curved little fingers (clinodactyly), difiiculty straightening out the arms completely (radioulnar synostosis), an armspan that exceeds height, a depression in the chest (pectus excavatim), occasionally undescended testicles or hypospadias (urethra under the penis rather than at the tip), leg length greater than head to seat height. Children with xxy may have low muscke tone, and may have delays indevloping lnguage. Some appear to have mild autism.

Yes, Klinefelter's syndrome is due to the XXY genotype.

Here is a link discussing this condition. The simple answer is only in severe cases can the lifespan of the affected person be shortened.

hi my name is ken i want to know about klinefelter syndrome disease progession so i can do my power point in my class. oh yeah tell me easy answer because i am only 15 year old THANKS MAN As far as I'm aware, it doesn't "progress" as such as it's not a disease but a genetic condition. If you're that interested, look it up on Wikipedia. :)

It is not very likely that this Syndrome will be passed down because about 1 in every 500 to 800 males inherits this allele.

It is not possible for it to be passed down from parents because it is not a trait or a gene it is just a disorder that happens when the DNA is being copied or if there is some sort of damage done to the DNA but no it canot be passed down from one generation to another.

Yes a karyotype is performed which is a blood test to be able to look at the number of chromosomes a person has, and therefore would be able to identify the extra X chromosome in case someone has it.

Stiff person syndrome is believed to be caused by an autoimmune response that affects the muscles and nerves, leading to stiffness and spasms. It is thought that a combination of genetic predisposition and environmental triggers play a role in the development of this rare neurological disorder.

You must make sure he has all the symptoms. People with klinefelter haven't just got small testes; there are some things you can see on the outside. These are some of the symptoms:

* They have a rather tall, thin body

* They aren't to muscular

* They have small testicles

The true cause of DWM is unknown. However, the components of the malformation seem to be related to a disruption in development of the middle portion of the lower part of the brain in the embryonic stage

In the United States, the incidence is approximately 1.64 cases per 100,000 people per year. Internationally, PTS has been described in many countries around the world, although specific rates of incidence have not been reported.

No. People with Klinefelter's syndrome have a normal Y chromosome and 2 normal X chromosomes.

No, it does not have Klinefelter's syndrome. it is just a mix-breed cat, otherwise known as a mutt for cats. It is a tabby/calico mix-breed. It is not rare and it is not a disease. it is just an unusual color pattern found on a tabby/calico mix. So don't be worried your cat is perfectly fine. I hope this helped.

47,XXY. This means that he has 47 chromosomes, including 2 X chromosomes and 1 Y chromosome.

Raynaud's syndrome can be classified as one of two types: primary, or idiopathic (of unknown cause) disease; and secondary, which is also called Raynaud's phenomenon.

what is kinefelter syndrome?

by tearing thatha poolu aaya koothi is very much worried.....

Klinefelter Syndrome is not caused by genes but is rather caused by chromosomal nondisjunction, or an odd number of chromosomes. Klinefelter Syndrome is particularly the presence of more than one X chromosome in a male's karyotype in addition to one Y chromosome (normal males have one X and one Y). Typically, a Klinefelter patient will feature the XXY karyotype, although the presence of additional X chromosomes has been reported. The adverse phenotypes associated with Klinefelter Syndrome are due to complications arising from gene dosage, or the amount of gene expression, not due to the presence of a certain gene or mutation.

The X chromosome is affected, because there are 2 of them (and a Y chromosome).
