Background: MKRN3 (Makorin Ring Finger Protein 3) is a maternally imprinted intronless gene located in the Prader-Willi syndrome locus (chromosome 15q11.2-q13). It is recognized that MKRN3 loss-of-function mutations are the primary cause of familial central precocious puberty (CPP). The MKRN3 protein primarily acts as an E3 ubiquitin ligase, and its activity is essential for controlling the timing of puberty, functioning as a brake on gonadotropin-releasing ho...

Background: Children with familial forms of central diabetes insipidus (CDI) display polyuria and polydipsia within the first years of life.Objective and hypotheses: We hypothesize that children with an early-onset idiopathic CDI might be affected by de novo genetic mutations.Method: Eleven children aged between 1 month and 7 years with polyuria and polydipsia and negative family history were enrolled. In nine of them with...
