What is monosomy X?
Quick Answer
Monosomy X is a condition in which a person has only one complete X chromosome instead of two sex chromosomes. In humans, this is known as Turner syndrome.
The Full Story
Monosomy X usually means a person has 45 chromosomes instead of the typical 46, with one missing sex chromosome. Turner syndrome occurs in females and can affect growth, ovarian development and heart or kidney function. Many cases are diagnosed in childhood or adolescence, though some are found before birth. The condition can vary widely in severity because some individuals have mosaic forms with different cell lines.
