La sindrome di Klinefelter è una malattia genetica, cronica ed ex rara, caratterizzata da un'anomalia cromosomica in cui un individuo di sesso maschile possiede un cromosoma X soprannumerario Het syndroom van Klinefelter is een genetische aandoening bij de man waarbij hij in zijn cellen ten minste een X-chromosoom te veel heeft. Het syndroom komt in meer varianten voor, waarvan de eenvoudigste 47,XXY-karyotype heet, dat wil zeggen dat er 47 chromosomen per cel zijn (het normale aantal is 46) waarvan XXY de geslachtschromosomen zijn In 1942, Klinefelter et al published a report on 9 men who had enlarged breasts, sparse facial and body hair, small testes, and an inability to produce sperm. In 1959, these men with Klinefelter syndrome were discovered to have an extra X chromosome (genotype XXY) instead of the usual male sex complement (genotype XY) The most common variations involve a trisomy, which means three sex chromosomes instead of the typical two. Girls who are born with an extra X chromosome are referred to as having Triple X or Trisomy X. Boys who are born with an extra X chromosome have 47,XXY, also known as Klinefelter syndrome It's important to remember that because symptoms can be mild, many males with KS are never diagnosed ore treated. 1 The earlier in life that KS symptoms are recognized and treated, the more likely it is that the symptoms can be reduced or eliminated. 2 It is especially helpful to begin treatment by.

These forms can arise from a 46,XY zygote or a 47,XXY zygote 47,XYY syndrome is characterized by an extra copy of the Y chromosome in each of a male's cells. Although many males with this condition are taller than average, the chromosomal change sometimes causes no unusual physical features
