Background: Central precocious puberty (CPP) results from activation of the hypothalamic-pituitary-gonadal axis before the age of 8 years in girls and 9 years in boys. The molecular basis of the maturation of this axis is still poorly understood. The MRKN3 gene located in the Prader-Willi syndrome critical region (chromosome 15q11–q13), inhibit factors stimulating pulsative. GnRH secretion. In 2013 inactivating mutations in the MRKN3 gene were discovered...
