Type of disease: Rare conditions
Miller-Dieker syndrome is a genetic condition characterized by lissencephaly, typical facial features, and severe neurologic abnormalities. Symptoms may include severe intellectual disability, developmental delay, seizures, muscle stiffness, weak muscle tone and feeding difficulties. Miller-Dieker syndrome is caused by a deletion of genetic material near the end of the short (p) arm of chromosome 17. Treatment is symptomatic and supportive.
