Abstract
Background: Non-immune hydrops fetalis (NIHF) is a pathological condition associated with high perinatal mortality, particularly in preterm neonates. It is manifested by extensive subcutaneous edema and accumulation of fluid in the body cavities of newborns. NIHF can have different causes. One of them is thought to be a group of abnormalities in the RAS-MAPK (RAS-mitogen activated protein kinase) signaling pathway genes, whose products are involved in information transfer from the cell membrane to the cell nucleus.
Case report: NIHF is characterized by a complex diagnostic process and multimodal treatment approaches during the postnatal period. A premature male infant was delivered by emergency caesarean section at 31 weeks due to rapidly developing NIHF. Noonan syndrome was eventually diagnosed. Clinically, the infant presented with severe generalized edema and multiple congenital malformations.
Conclusion: RAS-pathies have been reported to be a cause of various fetal structural abnormalities. This observation would be an addition to the existing data on prenatal phenotypes of Noonan syndrome caused by PTPN11 mutations. Whole-exome sequencing demonstrated its advantage in the diagnosis of prenatal disorders, while the result of conventional karyotyping or chromosomal microarray analysis did not reveal abnormalities.
