Where does Klinefelter’s syndrome occur?
Klinefelter syndrome occurs as a result of a random error that causes a male to be born with an extra sex chromosome.
It isn’t an inherited condition.
Humans have 46 chromosomes, including two sex chromosomes that determine a person’s sex.
Females have two X sex chromosomes (XX)..
Is Klinefelter syndrome more common in one ethnicity?
About 3% of the infertile male population have Klinefelter syndrome. The condition appears to affect all racial and ethnic groups equally.
Is Klinefelter syndrome classed as a disability?
Intellectual disability occurs in males with Klinefelter syndrome variants, who have a higher number of X chromosomes. About 70% of patients have minor developmental and learning disabilities.
Does Klinefelter syndrome cause mental retardation?
Klinefelter syndrome (KS) has not typically been associated with mental retardation (MR), however, in recent years a growing body of evidence suggested that KS boys often experience language deficits and academic difficulties.
What is the life expectancy of a person with Klinefelter syndrome?
According to research, Klinefelter syndrome can shorten your life expectancy up to two years. However, you can still live a long, full life with this condition. The earlier you get treatment, the better your outlook will be.
Is Klinefelter syndrome considered intersex?
Other intersex conditions, including the last four conditions listed above—complete androgen insensitivity, Klinefelter syndrome, Turner syndrome, and vaginal agenesis—usually do not result in ambigu- ous genitals and may not be recognized at birth.
Are XXY males infertile?
Main Points. Klinefelter syndrome (KS) is the most common chromosomal disorder in men and is associated with hypergonadotropic hypogonadism and infertility. Early hormonal therapy is recommended for patients with KS to assure normal puberty and prevent long-term consequences of hypogonadism.
Can a female have Klinefelter’s syndrome?
Klinefelter syndrome (47,XXY) results from an additional X chromosome on an XY background; therefore, this condition affects only males.
Can Klinefelter syndrome be cured?
There’s no cure for Klinefelter syndrome, but some of the problems associated with the condition can be treated if necessary. Possible treatments include: testosterone replacement therapy. speech and language therapy during childhood to help with speech development.
What race is affected by Klinefelter syndrome?
About 1 in every 500 to 800 males is born with this disorder; approximately 3000 affected boys are born each year in the United Sates. About 3% of the infertile male population have Klinefelter syndrome. The condition appears to affect all racial and ethnic groups equally.
What does XXY syndrome mean?
Klinefelter syndrome is a genetic condition in which a boy is born with an extra X chromosome. Instead of the typical XY chromosomes in men, they have XXY, so this condition is sometimes called XXY syndrome. Men with Klinefelter usually don’t know they have it until they run into problems trying to have a child.
Who is most likely to get Klinefelter syndrome?
Klinefelter syndrome occurs in about 1 out of 500 to 1,000 baby boys. Women who get pregnant after age 35 are slightly more likely to have a boy with this syndrome than younger women.
How common is XXY chromosome?
This XXY chromosome arrangement is one of the most common genetic variations from the XY karyotype, occurring in about one in 500 live male births.
How do you know if you have Klinefelter’s syndrome?
To find out if your son has Klinefelter syndrome, your doctor will ask questions about his past health, do a physical exam, and order a chromosome test called a karyotype. In adult men, lab tests in addition to a karyotype may be done, such as hormone tests or a semen analysis, if Klinefelter syndrome is suspected.
Does Klinefelter syndrome run in families?
Klinefelter syndrome isn’t passed down through families like some genetic diseases. Instead, it happens randomly from an error in cell division when a parent’s reproductive cells are being formed.
