SHE
The Mysterious ‘She Gene‘: Unraveling its Impact on Health
Description
The ‘she gene‘, also known as the ZFX or ZFY gene, is located on the X and Y chromosomes, respectively. This gene plays a crucial role in determining the sex of an individual. In biological females (XX), the ZFX gene is active on the X chromosome, while the ZFY gene is suppressed on the other X chromosome. Conversely, in biological males (XY), the ZFY gene is active on the Y chromosome, while the ZFX gene is suppressed on the X chromosome.
Associated Diseases
Dysregulation or mutations in the ZFX or ZFY gene can lead to a variety of developmental disorders, including:
- Turner syndrome: Occurs in females (45,X) who have only one X chromosome and the ZFX gene is absent or non-functional. Symptoms include short stature, ovarian dysfunction, and learning difficulties.
- Testicular dysgenesis (XY gonadal dysgenesis): Affects males (46,XY) who have a mutation in the ZFY gene, leading to underdeveloped testes and infertility.
- 47,XXY syndrome (Klinefelter syndrome): Occurs in males who have an extra X chromosome (47,XXY) and the ZFY gene is inactive. Symptoms may include learning disabilities, behavioral problems, and infertility.
Did you Know ?
Approximately 1 in 1000 females is affected by Turner syndrome, making it the most common genetic disorder among females.
