What are the different types of Turner syndrome?
There are 2 types of Turner syndrome: monosomy X TS and mosaic TS . About half of all girls with Turner syndrome have a monosomy disorder. Monosomy means that a person is missing one chromosome in the pair. Instead of 46 chromosomes, the person has only 45 chromosomes.
