While no cure is known, a number of treatments may help. Klinefelter syndrome is one of the most common chromosomal disorders , occurring in one to two per 1, live male births.
The primary features are infertility and small poorly functioning testicles. As babies and children, XXY males may have weaker muscles and reduced strength.
As they grow older, they tend to become taller than average. They may have less muscle control and coordination than other boys of their age.
During puberty, the physical traits of the syndrome become more evident; because these boys do not produce as much testosterone as other boys, they have a less muscular body, less facial and body hair, and broader hips.
As teens, XXY males may develop breast tissue [17] and also have weaker bones, and a lower energy level than other males.
By adulthood, XXY males look similar to males without the condition, although they are often taller. In adults, possible characteristics vary widely and include little to no sign of affectedness, a lanky , youthful build and facial appearance, or a rounded body type with some degree of gynecomastia increased breast tissue.
Affected males are often infertile , or have reduced fertility. Advanced reproductive assistance is sometimes possible.
Because of primary hypogonadism, individuals often have a low serum testosterone level, but high serum follicle-stimulating hormone and luteinizing hormone levels.
XXY males are more likely than other men to have certain health problems, such as autoimmune disorders , breast cancer , venous thromboembolic disease , and osteoporosis.
Some degree of language learning or reading impairment may be present, [27] and neuropsychological testing often reveals deficits in executive functions , although these deficits can often be overcome through early intervention.
Maternal age is the only known risk factor. The extra chromosome is retained because of a nondisjunction event during paternal meiosis I , maternal meiosis I , or maternal meiosis II gametogenesis.
The relevant nondisjunction in meiosis I occurs when homologous chromosomes, in this case the X and Y or two X sex chromosomes, fail to separate, producing a sperm with an X and a Y chromosome or an egg with two X chromosomes.
Another mechanism for retaining the extra chromosome is through a nondisjunction event during meiosis II in the egg. Nondisjunction occurs when sister chromatids on the sex chromosome, in this case an X and an X, fail to separate.
This XXY chromosome arrangement is one of the most common genetic variations from the XY karyotype, occurring in about one in live male births.
In mammals with more than one X chromosome, the genes on all but one X chromosome are not expressed; this is known as X inactivation.
Additional chromosomal material can contribute to cardiac, neurological, orthopedic, and other anomalies.
Often symptoms are milder in mosaic cases, with regular male secondary sex characteristics and testicular volume even falling within typical adult ranges.
Analogous XXY syndromes are known to occur in cats —specifically, the presence of calico or tortoiseshell markings in male cats is an indicator of the relevant abnormal karyotype.
As such, male cats with calico or tortoiseshell markings are a model organism for KS, because a color gene involved in cat tabby coloration is on the X chromosome.
The standard diagnostic method is the analysis of the chromosomes' karyotype on lymphocytes. A small blood sample is sufficient as test material.
In the past, the observation of the Barr body was common practice, as well. Physical characteristics of a Klinefelter syndrome can be tall stature, low body hair and occasionally an enlargement of the breast.
There is usually a small testicle volume of 1—5 ml per testicle standard values: 12—30 ml. A spermiogram can also be part of the further investigation.
Often there is an azoospermia present, rarely an oligospermia. The genetic variation is irreversible, thus there is no causal therapy.
From the onset of puberty, the existing testosterone deficiency can be compensated by appropriate hormone replacement therapy.
If gynecomastia is present, the surgical removal of the breast may be considered for both the psychological reasons and to reduce the risk of breast cancer.
The use of behavioral therapy can mitigate any language disorders, difficulties at school, and socialization. An approach by occupational therapy is useful in children, especially those who have dyspraxia.
Methods of reproductive medicine, such as intracytoplasmic sperm injection ICSI with previously conducted testicular sperm extraction TESE , have led to men with Klinefelter's syndrome to produce biological offspring.
The lifespan of individuals with Klinefelter syndrome appears to be reduced by approximately 2. This syndrome, evenly distributed in all ethnic groups , has a prevalence of one to two subjects per every males in the general population.
The syndrome is also the main cause of male hypogonadism. Children with Klinefelter syndrome may have low muscle tone hypotonia and problems with coordination that may delay the development of motor skills, such as sitting, standing, and walking.
Affected boys often have learning disabilities, resulting in mild delays in speech and language development and problems with reading.
Boys and men with Klinefelter syndrome tend to have better receptive language skills the ability to understand speech than expressive language skills vocabulary and the production of speech and may have difficulty communicating and expressing themselves.
About 10 percent of boys and men with Klinefelter syndrome have autism spectrum disorder. Nearly half of all men with Klinefelter syndrome develop metabolic syndrome, which is a group of conditions that include type 2 diabetes , high blood pressure hypertension , increased belly fat, high levels of fats lipids such as cholesterol and triglycerides in the blood.
Compared with unaffected men, adults with Klinefelter syndrome also have an increased risk of developing involuntary trembling tremors , breast cancer if gynecomastia develops , thinning and weakening of the bones osteoporosis , and autoimmune disorders such as systemic lupus erythematosus and rheumatoid arthritis.
Autoimmune disorders are a large group of conditions that occur when the immune system attacks the body's own tissues and organs. Klinefelter syndrome affects about 1 in newborn boys.
It is among the most common sex chromosome disorders, which are conditions caused by changes in the number of sex chromosomes the X chromosome and the Y chromosome.
Klinefelter syndrome is a sex chromosome disorder in boys and men that results from the presence of an extra X chromosome in cells.
People typically have 46 chromosomes in each cell, two of which are the sex chromosomes. Most often, boys and men with Klinefelter syndrome have the usual X and Y chromosomes, plus one extra X chromosome, for a total of 47 chromosomes 47,XXY.
Boys and men with Klinefelter syndrome have an extra copy of multiple genes on the X chromosome. The activity of these extra genes may disrupt many aspects of development, including sexual development before birth and at puberty, and are responsible for the common signs and symptoms of Klinefelter syndrome.
Researchers are working to determine which genes contribute to the specific developmental and physical differences that can occur with Klinefelter syndrome.
Some people with features of Klinefelter syndrome have an extra X chromosome in only some of their cells; other cells typically have one X and one Y chromosome.
Rarely, other cells may have additional chromosome abnormalities. It is thought that less than 10 percent of individuals with Klinefelter syndrome have the mosaic form.
Boys and men with mosaic Klinefelter syndrome may have milder signs and symptoms than those with the extra X chromosome in all of their cells, depending on what proportion of cells have the additional chromosome.
Several conditions resulting from the presence of more than one extra sex chromosome in each cell are sometimes described as variants of Klinefelter syndrome.
Like Klinefelter syndrome, these conditions affect male sexual development and can be associated with learning disabilities and problems with speech and language development.
However, the features of these disorders tend to be more severe than those of Klinefelter syndrome and affect more parts of the body.
As doctors and researchers have learned more about the differences between these sex chromosome disorders, they have started to consider them as separate conditions.
Klinefelter syndrome is not inherited; the addition of an extra X chromosome occurs during the formation of reproductive cells eggs or sperm in one of an affected person's parents.
During cell division , an error called nondisjunction prevents X chromosomes from being distributed normally among reproductive cells as they form.
Typically, as cells divide, each egg cell gets a single X chromosome, and each sperm cell gets either an X chromosome or a Y chromosome. However, because of nondisjunction, an egg cell or a sperm cell can also end up with an extra copy of the X chromosome.
If an egg cell with an extra X chromosome XX is fertilized by a sperm cell with one Y chromosome, the resulting child will have Klinefelter syndrome.
March 9, Full Review…. February 10, Rating: B- Full Review…. November 15, Rating: 3. View All Critic Reviews Jan 01, XXY is a coming of age film, but with an interesting and provocative twist; the main character is a hermaphrodite.
This may be shocking to some, but I found this aspect of the film, as well as that of the parallel coming of age tale of the visiting male teen, quite interesting.
Unfortunately, the same can't be said about the dialog of the film or the translation of the dialog to be specific.
The film tend to dawdle, spending too much time creating atmosphere and a feeling of normalcy like showing a family dinner with friends where absolutely nothing happens to move the story along.
She for that is how "it" is perceived is wrestling with her identity and is considering the male aspects of her physiology. She experiments being the "dominant" with a slightly older boy - a family friend who is also struggling with his identity he may have gay tendencies, or is just curious The father of the visiting boy has turned his back on his son as he believes the boy does indeed have a hankering for other boys.
He is also a surgeon, and insinuates that he would be happy to take a little snip at the "daughter's" problem. If this all sounds intriguing, it is.
But the pace and some of the directorial decisions seem to muck up the matter. That the boy doesn't respond and the film shows a close-up of his face, which displays NOTHING , you wonder what the message was - man, this climax could have been handled so much better!
Nov 01, A sensitive film that deals with an uncomfortable subject and handles it with quiet dignity. A family moves from their native Argentina to a remote area of Uruguay in order to shield their "daughter" from ridicule over her abnormal physical attributes.
But things have reached a point where the "girl" must choose whether to continue to live her life as a female or embrace her masculine identity.
The shame of the parents and the agony that Alex faces as she makes her choice is what provides the conflict in the story. Complicating the process is another young man facing his own sexual identity issues of a different sort being thrust into the already stressed family environment.
The director could have emphasized all of the more prurient aspects of the central dilemma, but chose a more subtle approach and therefore allowed the viewer to fully empathize with the struggles these two teens face.
Strong characters, a solid story and very few false notes made what could have been a difficult film a very thought provoking experience.
In the end, we have a clear idea of the decisions that have been made and we understand that the roads chosen will not be easy.
