Background: Severe Ovarian Dysgenesis (OD), a rare heterogeneous XX disorder of Sex Development (XX-DSD) presents clinically with primary amenorrhea, hypergonadotrophic hypogonadism and infertility. The genetic basis of OD remains unknown in about 70% of cases. To identify novel causes of OD, we study patients in which known genes have been excluded.Methods: Whole-exome-sequencing was performed on DNA extracted from peri...
