Introduction: Short stature is a common finding that affects per definition about 3% of the population. Isolated, severe short stature may be treated successfully with recombinant human growth hormone (rhGH). Currently, rhGH is offered to short children with specific disorders or biochemically proven growth hormone deficiency (GHD). However, biochemical testing for GHD is artificial and therefore controversial. Adding genetic testing may improve the diagnostic...

Background: NR5A1/SF-1 variants result in a wide range of phenotypes including DSD, male infertility, and primary ovarian insufficiency (POI). Little is known of how NR5A1/SF-1 variants affect puberty in individuals with or without DSD. This study aimed to assess the impact of NR5A1/SF-1 variants on pubertal development and investigate whether abnormal puberty is linked to the severity of DSD in an international cohort with NR5A1...

Background: Inhibin consists of two homologous subunits, the α (INHA) and the βA or βB subunits (INHBA/INHBB). Both inhibins play an important role in the hypothalamic-pituitary-gonadal axis by regulating the follicle stimulating hormone levels. INHA knockout mice develop mixed or incompletely differentiated gonadal stromal tumours. In females, some INHA variants have been associated with primary ova...

Background: Loss of function variants in Steroidogenic Factor 1 (NR5A1/SF-1) lead to a broad spectrum of phenotypes, but data on the whole picture of phenotypes are currently lacking. We aimed to investigate the phenotype of individuals with SF-1 variants in a large international cohort.Methods: We identified the individuals through the international I-DSD network and through contacting researchers from previous publicat...
