Progressive non-immune hydrops fetalis associated with RASA1 mutation: prenatal imaging and genomic insights.

BMJ case reports - 27 Feb 2026

Abstract excerpt

Hydrops fetalis (HF) is the pathological accumulation of fluid in two or more fetal compartments. While immune-mediated HF was historically predominant, non-immune hydrops fetalis (NIHF) is now increasingly common. Advances in genetic testing have revealed monogenic causes, including RASopathies (a group of genetic syndromes caused by dysregulation of the RAS-mitogen-activated protein kinase signalling pathway)....
