klinefelter syndrome
LowTechnical/Medical
Definition
Meaning
A genetic condition in males caused by an extra X chromosome (XXY), leading to reduced testosterone and often infertility.
A chromosomal variation affecting male physical and cognitive development, associated with specific physical traits (e.g., taller stature, less body hair), potential learning difficulties, and increased risk of certain health conditions like osteoporosis and autoimmune disorders.

The presence of an extra X chromosome (47,XXY instead of the typical 46,XY).
Yes, while 47,XXY is most common, variants include 48,XXXY, 48,XXYY, or mosaic patterns (where only some cells have the extra X).
