Purpose: We report on the results of the whole-genome analysis performed in a patient who developed severe ovarian hyperstimulation syndrome (OHSS) following gonadotropin-releasing hormone (GnRH) agonist triggering in a "freeze-all" protocol.
Methods: A 30-year-old patient with polycystic ovary syndrome who developed severe early-onset OHSS with clinical ascites, and slight renal and hepatic dysfunction was admitted for monitoring and treatment with cabergoline and intravenous albumin. Exome sequencing to assess for any known genetic predisposition for OHSS was performed.
Results: No known genetic variants associated with OHSS predisposition were found.
Conclusions: Case reports of severe OHSS following a "freeze-all" strategy are starting to arise, showing that OHSS has not been completely eliminated with this approach. Further studies should be conducted to confirm if such cases may be due to genetic predisposition or not.
