Klinefelter Syndrome, or XXY Syndrome, is one of the main genetic disorders among men: it occurs in 576, according to the study carried out at the beginning of the 1990s by the Aarhus Psychiatric Hospital in Denmark.
Man has 23 pairs of chromosomes and the latter determines sex. In the case of women, both chromosomes (XX) are equal and, in both cases, form two different chromosomes (XY).
Men with syndrome have at least one X, in most cases 47, the XXY karyotype or, in rare cases, 48, XXXY or 49, XXXXY karyotypes. That's why Klinefelter Syndrome is called XXY Syndrome.
There is one major consequence of the loss of testosterone production, male sex hormone. The body of the human being does not naturally produce, so they are injected each month every time they detect the syndrome.
In many men with Klinefelter, though not genitals do not fully develop and sleep because they have difficulty producing testosterone.
As a result, breasts grow more than normal and adolescence can be delayed or it does not occur.
Considering the low hormone production, fertility is damaged. If the syndrome is detected early, infertility can also stop.
In addition, a type 2 diabetes, blood coop, unwanted tremor, breast cancer, osteoporosis, rheumatoid arthritis and lupus is more likely to develop depending on the United States National Library of Medicine.
"The problem is that many people do not diagnose it," he says. It's a condition that I know, even though some of them suffer, I do not understand"Diego Yeste, head of the pediatric endocrinology hospital in Hebron hospitals, says Barcelona.
Nowadays, In Spain, the Klinefelter syndrome has been diagnosed with amniocentesis during the pregnancy test.
A sample of the amniotic fluid is extracted, which analyzes genetic modifications like this. In the face of a serious fetal abnormality, the mother may request abortion during the first 22 weeks.
