The relationship between KISS1-GPR54 gene and precocious puberty of children

Precocious puberty in children begins with the increased pulsatile secretion of the gonadotrophin-releasing hormone(GnRH)from hypothalamic.Recently,KISS1-GPR54 Was found to be a key factor to regulate the secretion of GnRH and the onset of puberty.Kisspeptin interacts with its receptor GPR54.which expressed on the hypothalamic GnRH neurons.and affects GnRH pulsatile release and the onset of puberty.GPR54 gene mutation causes the incidence of GnRH-dependent precocious puberty. Key words: KISSI-GPR54; Precocious puberty; Gene mutation
