GPER1 and hydrops fetalis: Machine learning filtering further prioritized 10 hub genes: GPER1, E2F5, DZIP3, CYLD, ADAMTS2, ZNF366, ST14, SNORD28, LHFPL2, and HIVEP2. These hubs were significantly associated with immune-related processes, suggesting their potential role in the pathogenesis of HF after MI.
