Brain-lung-thyroid syndrome

Choreoathetosis, hypothyroidism, and neonatal respiratory distress is a syndrome of congenital hypothyroidism associated with pulmonary problems, mental retardation, muscular hypotonia and persistent ataxia which could be described as choreoathetosis. This disorder is attributed to mutations of the NKX2.1, a homeodomain transcription factor expressed in the developing thyroid, respiratory epithelium, and specific areas of the forebrain during embryogenesis.
