Introduction: Recently novel approaches, through implementation of next-generation sequencing (NGS) in clinical practice for genetic evaluation of idiopathic short stature, has permitted to identify new variants of genes which modulate function of growth plate, including heterozygous mutations of the aggrecan gene. Aggrecan, a large chondroitin sulfated proteoglycan, is a major structural component of the extracellular matrix of cartilage, including growth pla...

Background: MKRN3 gene, encoding Makorin RING-finger protein 3, is a maternally imprinted gene located at a Prader-Willi syndrome region on chromosome 15q11.13. Deleterious mutations of MKRN3 gene are a common cause of paternally inherited central precocious puberty (CPP), being identified in 33-46% of familial cases and in about 5% and 40% of apparently sporadic female and male cases, respectively.Objectives: To evaluate the presence o...

Introduction: The major genetic cause of CPP is the paternally inherited Makorin RING-finger protein 3 (MKRN3) deficiency. Rare patients carry variants in kisspeptin and its receptor and DLK1.Objectives: To identify genetic causes of CPP.Population and methods: MKRN3 Sanger sequencing was performed in 56 unrelated subjects (12 familial non-maternal, 44 sporadic (6 boys)), whole-ge...
