A new pathway in the control of the initiation of puberty: the MKRN3 gene

Pubertal timing is influenced by complex interactions among genetic, nutritional, environmental, and socioeconomic factors. The role of MKRN3, an imprinted gene located in the Prader-Willi syndrome critical region (chromosome 15q11-13), in pubertal initiation was first described in 2013 after the identification of deleterious MKRN3 mutations in five families with central precocious puberty (CPP) using whole-exome sequencing analysis. Since then,...
