Overview
Isotretinoin-like syndrome is a very rare condition that a baby is born with, meaning it is present from birth (congenital). It is also sometimes called 'retinoic acid embryopathy-like syndrome' because the pattern of birth differences looks very similar to what can happen when a pregnant person takes the acne medication isotretinoin (brand name Accutane) during pregnancy — even when no such medication was taken. The syndrome causes a recognizable pattern of physical differences that affect the face, ears, heart, and brain. Babies born with this condition often have small or unusually shaped ears, heart defects, a small head (microcephaly), and differences in how the brain develops. Some children also have intellectual disability and learning challenges. The face may look different in specific ways, such as a small jaw or widely spaced eyes. There is currently no cure for isotretinoin-like syndrome. Treatment focuses on managing each individual symptom or health problem. This means a child may need heart surgery, hearing support, developmental therapies, and educational support depending on which parts of the body are affected. A team of different specialists usually works together to give the best care.
