Background: 46XY DSD with female phenotype is classified as complete gonadal dysgenesis (46XY CGD) if a uterus is present or a disorder of androgen synthesis or action if a uterus is absent. The genetic causes of 46XY CGD are not fully clarified. Less than 15% of the cases were found to carry mutations of the sex determining region Y gene (SRY).Purpose: The description of the rare case of two sisters affected of 46XY CPD and gonadoblastoma with SRY mutat...

The proband is a 12 yr old Caucasian European girl with grade 3 obesity, developmental delay and hyperphagia. She was born at term via an uncomplicated pregnancy and exhibited neonatal hypotonia, difficulty feeding, failure to thrive and delayed attenuation of milestones. At the age of 2 years she started developing hyperphagia and rapid excessive weight gain. Molecular analysis for Prader Willi syndrome and array CGH were negative. At the age of 10 yrs she was diagnosed with ...

Background: FOXE1 gene variants containing alterations in the alanine tract length may confer susceptibility to primary ovarian insufficiency (POI). BMP15 gene variants have also been related to POI.Objective and hypotheses: To evaluate the contribution of FOXE1 and BMP15 variants in the pathogenesis of POI and to investigate the hypothesis of digenic inheritance in this disorder.Method: FOXE1 and BMP...
