[Progress in genetic research on non-immune hydrops fetalis].

Non-immune factors are the most common cause of hydrops fetalis, which may manifest as abnormal accumulation of fluid in the body cavities. Hydrops fetalis is a complex condition with a high mortality rate. The prognosis is depending on the underlying disease and is particularly poor in those with chromosomal aberrations or monogenic disorders. In this paper, advance in the research on non-immune hydrops fetalis is reviewed.
