Fryns syndrome is a condition that affects the development of many parts of the body. Signs and symptoms vary widely among affected individuals. Many affected individuals have a defect in the diaphragm muscle such as a congenital diaphragmatic hernia (a hole in the diaphragm present at birth). This may allow the stomach and intestines to move into the chest, which can result in pulmonary hypoplasia (underdevelopment of the lungs). Other signs and symptoms may include abnormalities of the fingers and toes; distinctive facial features; severe developmental delay and intellectual disability; and abnormalities of the brain, cardiovascular system, gastrointestinal system, kidneys, and genitalia. Most affected individuals die before birth or in early infancy. The cause of the condition is not known, but it is thought to be genetic and appears to be inherited in an autosomal recessive manner.[1]
