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)).
The only way to be 100% sure if you have Klinefelter's syndrome is to get a genetic analysis done, but short of that you can compare yourself to the symptoms of a person with Klinefelter's to determine if you match that description. If you do match that description, then I would urge you contact your doctor to get a proper diagnosis.
Here are the more common symptoms occurring in Klinefelter's syndrome:
Infertility
Difficulty learning language
Deficits in cognitive executive functioning
Gynecomastia (male breast development)
Widened, rounded hips
Narrow shoulders
Tall, lanky build
Small testicles or small penis
Underdeveloped muscle mass
Little or no pubic, facial, or body hair
Decreased impulse control
Decreased ability to multi-task
Lengthened response time to a stimulus
Poor social skills
Increased risk for developing alcohol/drug abuse
Increased risk for developing psychiatric disorders
not test for determination k f syndrome by symptoms after birth
Yes. A person can be screened at any age for Klinefelter's, even on a fetus.
I don't know tell me the answer
they have a extra chromosome, a normal male is XY, a male with klinefelters is XXY.
Yes i belive it is ny g
X-linked
Physically, no; mentally, that's up to the strength of the individual.
Yes animals do sometimes have Turner's syndrome or Klinefelter's syndrome with similar characteristics as those observed in humans.
Klinefelters is sex chromosome trisomy. Down Syndrome is trisomy. One of the most common forms of MD is sex-linked and affects boys more frequently than it does girls.
Klinefelters Syndrome
No. People with Klinefelter's syndrome have a normal Y chromosome and 2 normal X chromosomes.
Nondisjunction, or sending both chromosomes to one cell during meiosis.
Yes. Enlarged Breasts is one characteristic
First a testicular biopsy should be done to determine if he has any viable sperm. Some men with this condition do have some viable sperm in their testicles and if he does, in-vitro fertilization may be a possibility. However, if he does not have any viable sperm, then you would need to use donor sperm to become pregnant. Hope this helps.
