PRL
The PRL Gene: A Key Player in Growth and Development
Description:
The PRL gene, also known as the prolactin gene, is located on chromosome 6 and encodes the hormone prolactin. Prolactin is a polypeptide hormone that is primarily produced by the pituitary gland in the brain. It plays a crucial role in regulating growth, development, and reproduction.
Associated Diseases:
Mutations or abnormalities in the PRL gene have been linked to several disorders, including:
- Hyperprolactinemia: Excessive levels of prolactin result in hyperprolactinemia. This can cause menstrual irregularities, infertility, and galactorrhea (breast milk production in non-nursing women).
- Prolactinoma: A benign tumor of the pituitary gland that produces prolactin, leading to hyperprolactinemia.
- Hypothyroidism: In some cases, PRL gene mutations can impair the thyroid-stimulating hormone (TSH) production, leading to hypothyroidism (underactive thyroid).
Did you Know ?
Prolactin levels are influenced by various physiological factors. For instance, women experience a significant surge in prolactin levels during pregnancy and breastfeeding.
