Detailed explanation-1: -To diagnose Turner syndrome, doctors use a special blood test that looks at chromosomes, called a karyotype test (chromosomal analysis). 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.

Detailed explanation-2: -Turner syndrome is a female-only genetic disorder that affects about 1 in every 2, 000 baby girls. A girl with Turner syndrome only has 1 normal X sex chromosome, rather than the usual 2. This chromosome variation happens randomly when the baby is conceived in the womb. It is not linked to the mother’s age.

Detailed explanation-3: -In females who have Turner syndrome, one copy of the X chromosome is missing, partially missing or changed. The genetic changes of Turner syndrome may be one of the following: Monosomy. The complete absence of an X chromosome generally occurs because of an error in the father’s sperm or in the mother’s egg.

Detailed explanation-4: -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. This means a girl with TS has only one X chromosome in her 23 rd pair.
