Detailed explanation-1: -Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.

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.

Detailed explanation-3: -Turner syndrome is a genetic disorder affecting girls and women. The cause of Turner syndrome is a completely or partially missing X chromosome. Turner syndrome symptoms include short stature and lack of breast development and periods. Treatment for Turner syndrome may include hormone therapy.

Detailed explanation-4: -Turner syndrome (TS) is a complex developmental disorder in individuals with short stature who possess a 45, X cell line, with or without mosaicism. Since the single X chromosome is maternally derived in 80%, the genesis of the 45, X karyotype is due to instability of the Y chromosome leading to its loss during meiosis.

Detailed explanation-5: -The protein product of the SHOX gene plays a role in the growth and maturation of the skeleton. Researchers believe that the loss of one SHOX gene on the altered X chromosome is the main cause of short stature in females with Turner syndrome.
