Final Height in Oncological Growth Hormone Deficient (GHD) Children After Growth Hormone (GH) Therapy

Rodari Giulia , Cattoni Alessandro , Albanese Assunta

Background: Growth hormone deficiency (GHD) is the commonest hypothalamic-pituitary (HP) disorder in cancer survivors. The only few studies in literature addressing GH efficacy in a large cohort of patients concluded that, though improving height outcome, GH therapy may not entirely restore final height (FH) potential according to mid-parental height (MPH). Thus, in order to optimize outcome, more information on factors influencing growth response in these chi...

Familial Central Precocious Puberty Caused by a Novel MKRN3 Mutation

Admoni Osnat , Bercovich Dani , Tenenbaum-Rakover Yardena

Background: Mutations in the imprinted gene MKRN3 have been associated with inherited central precocious puberty (CPP). MKRN3 is a maternal imprinted gene and the disease is exclusively paternally transmitted in an autosomal dominant manner. Although the mechanism is unclear, it has been suggested that MKRN3 inhibits hypothalamic GnRH release, leading to a loss-of-function mutation and CPP. To date, more than 20 MKRN3mutations have b...
