Detailed explanation-1: -Mosaic Turner syndrome: Also called 45, X mosaicism, this type makes up about 30% of Turner syndrome cases. Some of the baby’s cells have a pair of X chromosomes, while other cells only have one. It happens randomly during cell division early in pregnancy.

Detailed explanation-2: -Results that indicate TS show only one X chromosome instead of two X chromosomes, with a total of 45 chromosomes instead of the usual 46. Some girls with Turner syndrome have two X chromosomes detected, but one is missing a piece.

Detailed explanation-3: -Turner syndrome (also known as monosomy X) is a condition caused by monosomy . Women with Turner syndrome usually have only one copy of the X chromosome in every cell, for a total of 45 chromosomes per cell.

Detailed explanation-4: -While most people have 46 chromosomes, people with Turner syndrome usually have 45 in some or all cells. The chromosomal abnormality is often present in just some cells, in which case it is known as Turner syndrome with mosaicism.

Detailed explanation-5: -Normally, people are born with 23 chromosome pairs, or 46 chromosomes, in each cell-one inherited from the mother and one from the father. A numerical chromosome abnormality can cause each cell to have 45 or 47 chromosomes in each cell.
