Background: 46,XY Complete Gonadal Dysgenesis (Swyer Syndrome) is a rare cause for DSD with incidence ≈1:80000. It is characterised by defective formation of the gonads as a result of structural anomalies in the sex chromosomes or mutations in specific genes. In 20% of the patients deletion/mutation in SRY can be found. Mutations, deletions or duplications in other genes (NRD5A1, DHH, DAX1, WNT4, DMRT, etc.) are also reported. The phenotype is completely female and the d...

Background/Objectives: Hypergonadotropic hypogonadism (HH) is characterised by primary gonadal failure with excess of pituitary gonadotropin secretion. The causes can be congenital or acquired. Herein, we report a case of a 10-years-old-boy with obesity, development of HH during follow-up and a novel genetic variant in NR5A1 (SF1) gene with de novo origin.Methods: The child presented with obesity (started at the age of 5...
