Background: What initiates pubertal process in humans and other mammals has remained elusive.Objective and hypotheses: We hypothesize that gene(s), whose products trigger the GnRH pulse generator to restart ticking at the usual time of puberty, can be identified via autozygosity mapping together with whole exome sequencing in patients with idiopathic hypogonadotrophic hypogonadism (IHH).Method: We studied a cohort IHH cases. Functi...

Aim: Physical damage to hypothalamus, can lead to autonomic dysregulation, temperature imbalance, increased appetite, and obesity. We aim ed to determine the risk factors for the development of hypothalamic obesity.Methods: The cases were evaluated based on location, size of the mass, treatment modality (surgery or radiotherapy), pathology result, presence of hydrocephalus, family history of consanguinity and obesity, co...

Introduction: Homozygous leptin (LEP) and leptin receptor (LEPR) mutations lead to childhood-onset obesity due to deficient leptin signaling. The specific aims of this work are to explore genotype/phenotype correlations in a national multicenter cohort of 18 subjects with leptin (LEP) and leptin receptor (LEPR) deficiency, report on the long-term clinical follow-up of these rare cases, and systematically review all patients with pathogenic <e...
