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: Disorders of androgen synthesis are rare causes of 46,XY disorder of sex development (DSD) that present with undervirilization or sex reversal.Objective: A history of a female adolescent with 46,XY DSD, initially suspected to have complete androgen insensitivity is presented.Methods: Patient history was obtained from the medical records. Urinary steroid profile was preformed using gas chromatography/mass spectrometry. T...

Nicotinamide nucleotide transhydrogenase (NNT) is expressed in the heart, thyroid, and testicles, where it maintains the balance of reactive oxygen species in the mitochondria. It is linked, by an insufficiently described mechanism, to primary adrenal insufficiency (PAI) with or without mineralocorticoid insufficiency and several extra-adrenal manifestations (i.e. gonadal adrenal rest tumors, cardiomyopathy, hypothyroidism, and precocious puberty). A comprehensive and chronolo...
