Mosaicism:  In some belongings, a fault takes place in cell division through out initial stages of fetal growth. This results in some cells in the body having two whole facsimiles of the X chromosome. Further cells have only one counterfeit of the X chromosome.

X chromosome abnormalities:Irregular or lost shares of one of the X chromosomes can befall. Cells have one comprehensive and one changed copy. This fault can happen in the eggor sperm with all cells having one ample and one transformed copy.

Y chromosome material:  In a small percentage of Turner syndrome belongings, some cells have one replica of the X chromosome and former cells have one facsimile of the X chromosome and some Y chromosome substantial.
