Pierre Robin syndrome (PRS), or Pierre Robin sequence, is a rare birth defect that happens during fetal development. It’s a group of conditions that affect your baby’s jaw and mouth so it may be hard for them to breathe, nurse or feed from a bottle. Pierre Robin sequence is also known as Pierre Robin syndrome or Robin sequence.

Understanding the Context

It is a rare congenital birth defect characterized by an underdeveloped jaw, backward displacement of the tongue and upper airway obstruction. Cleft palate is also commonly present in children with Pierre Robin sequence. Pierre Robin sequence[a] (/ pjɛər rɔːˈbæ̃ /; [3] abbreviated PRS), also known as Pierre Robin syndrome, is a congenital defect observed in humans which is characterized by facial abnormalities. What is Pierre Robin syndrome?

Key Insights

Pierre Robin syndrome is a congenital condition recently linked to genetic anomalies at chromosomes 2, 11 or 17. Often called Pierre Robin sequence, the disease is a chain of developmental malformations, each leading to the next. Learn about Pierre Robin syndrome (aka Pierre Robin sequence) and how it can affect a baby’s breathing, feeding, hearing, and development. Pierre-Robin Syndrome (PRS), also known as Pierre Robin sequence, is a congenital condition that affects the lower jaw and palate. The three main features that characterize PRS are: cleft palate (opening in the roof of the mouth) severe underdevelopment of the lower jaw (retrognathia) Pierre Robin sequence is a series of birth defects.

Final Thoughts

Learn about causes, symptoms, diagnosis, treatment, outlook and associated conditions. In 20 to 40 percent of cases, the Pierre Robin sequence occurs alone. The exact causes of PRS are unknown, but likely include both genetic factors and pregnancy environmental factors. Pierre Robin Sequence (PRS) is a condition where babies are born with a cleft palate and a small lower jaw which can cause breathing and feeding difficulties in early life. This page explains how it happens, how it’s treated, and what support is available. The combination of features characteristic of Pierre Robin sequence can lead to difficulty breathing and problems eating early in life.

As a result, some affected babies have an inability to grow and gain weight at the expected rate (failure to thrive).
