EPHB4-related lymphatic-related hydrops fetalis

EPHB4-related lymphatic-related hydrops fetalis (also sometimes called EPHB4-related hydrops fetalis or LRHF) is a rare genetic condition that affects how fluid is managed in the body, particularly in unborn babies and newborns. It is caused by changes (mutations) in the EPHB4 gene, which plays an important role in the development of the lymphatic system — the network of vessels that helps drain excess fluid from body tissues. When this system does not work properly, fluid builds up in abnormal places, a condition called hydrops fetalis. This means fluid collects under the skin, around the lungs, around the heart, or in the belly of the baby before or shortly after birth. Babies with this condition may be identified before birth through routine ultrasound scans that show unusual fluid buildup. The severity can vary widely — some babies are severely affected and may not survive, while others may respond to treatment and improve over time. The lymphatic system problems can also cause ongoing issues with fluid drainage after birth, sometimes leading to swelling (lymphedema) in the limbs or other areas. Treatment is focused on managing symptoms. Before birth, doctors may drain excess fluid to help the baby breathe and develop. After birth, care is provided in a neonatal intensive care unit (NICU), and longer-term management of lymphatic problems may involve compression therapy, specialized physical therapy, and close monitoring. There is currently no cure, but research into this condition is growing as more cases are identified.
