Turner syndrome (TS), commonly known as 45,X, or 45,XO, [note 1] is a chromosomal disorder in which cells have only one X chromosome or are partially missing an X chromosome (sex chromosome monosomy) leading to the complete or partial deletion of the pseudoautosomal regions (PAR1, PAR2) in the affected X chromosome.
Turner syndrome – Females with Turner syndrome typically have one X chromosome instead of the usual two X chromosomes. Turner syndrome is the only full monosomy that is seen in humans — all other cases of full monosomy are lethal and the individual will not survive development.

Karyotype of X monosomy (Turner syndrome) This condition is characterized by the presence of only one X chromosome and no Y chromosome (see bottom right corner). Complete loss of an entire X chromosome accounts for about half the cases of Turner syndrome .
In 45,X/46,XY, most or all of the Y chromosome is lost in one of the newly created cells. All the cells then made from this cell will lack the Y chromosome. All the cells created from the cells that have not lost the Y chromosome will be XY. [11] The 46,XY cells will continue to multiply at the same time as the 45,X cells multiply.
Turner syndrome, also known as 45,X or 45,X0, is a chromosomal abnormality characterised by a partial or completely missing second X chromosome, [4] [24] [25] giving a chromosomal count of 45, instead of the typical count of 46 chromosomes. [24]

Turner syndrome is a condition in females in which there is partial or complete loss of one X chromosome. This causes symptoms such as growth and sexual development problems. In 15% of Turner syndrome patients, the structural abnormality is isochromosome X, which is composed of two copies of the q arm (i(Xq)).
