Turner's Syndrome

[Lorenzo]

Turner's Syndrome:  encompasses several conditions, of which monosomy X (absence of an entire sex chromosome, the Barr body) is most common. It is a chromosomal abnormality in which all or part of one of the sex chromosomes is absent (unaffected humans have 46 chromosomes, of which two are sex chromosomes). Normal females have two X chromosomes, but in Turner syndrome, one of those sex chromosomes is missing or has other abnormalities. Women with Turner's syndrome have neck webbing, infertility, and the maldevelopment of secondary female sexual characteristics.
