Background: Makorin RING finger protein 3 (MKRN3) is an important factor located on chromosome 15 in the imprinting Prader-Willi syndrome - associated region. Imprinted MKRN3 expressed in hypothalamic regions essential for puberty initiation and mutations have been found in patients with central precocious puberty (CPP). CPP caused by the early activation of pulsatile Gonadotropin releasing hormone (GnRH) secretion is clinically defined by the early maturation...
