Background: Basal levels of androgens, in particular 17-OHprogesterone (17OHP), are widely debated as predictors of non-classical congenital adrenal hyperplasia (NCCAH) among patients with precocious pubarche (PP). So many authors suggested the execution of ACTH stimulation test in all children with PP. The aim of our study was to identify clinical and biochemical predictors of NCCAH in children with PP.Methods: We conducted a prospective study of 92 pat...

Background: Central precocious puberty (CPP) is often familial but its genetic cause is largely unknown. Very recently, the makorin RING finger protein 3 (MKRN3) gene has been found mutated for the first time in 5 families with familial precocious puberty. The inheritance pattern is particular being the MKRN3 a maternal imprinted gene. Moreover in a recent genome wide association study common intronic or intragenic variants harbouring this gene and other two imprinted genes, D...

Background: The phenotype of SHOX aploinsufficiency is highly variable also in affected members of the same family with broad differences in severity of short stature, disproportion, presence of Madelung deformity.Case presentation: We present a family with a new mutation of SHOX gene. A 2.3 years old girl, born at term from unrelated parents, came to our observation for short stature. Her height was −2.02 SDS, arm span was normal, sitting heigh/he...
