What is the number of chromosomes affected in Klinefelter syndrome?

Klinefelter syndrome (KS) is a genetic condition where there’s an extra X chromosome present in a male’s genetic code. Instead of having a total of 46 chromosomes, they have 47 — with two copies of the X chromosome and one copy of the Y chromosome (47,XXY).

What is Klinefelter syndrome humans?

Klinefelter syndrome is a genetic condition that results when a boy is born with an extra copy of the X chromosome. Klinefelter syndrome is a genetic condition affecting males, and it often isn’t diagnosed until adulthood.

What is Klinefelter syndrome and what causes it?

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. Females have two X chromosomes (46,XX), and males have one X and one Y chromosome (46,XY).

Is Mosaic Klinefelter syndrome inherited?

Mosaic Klinefelter syndrome (46,XY/47,XXY) is also not inherited. It occurs as a random error during cell division early in fetal development. As a result, some of the body’s cells have the usual one X chromosome and one Y chromosome (46,XY), and other cells have an extra copy of the X chromosome (47,XXY).
