We report seven patients with the cerebro-costo-mandibular syndrome, a
multiple congenital anomaly syndrome with, as the most distinctive fe
atures extreme micrognathia and abnormal rib development. Twice a pare
nt to child transmission was found, compatible with autosomal dominant
mode of inheritance. One of our patients presented with absence of th
e auditory canals and subluxation of the radial head, and another with
choanal atresia, findings that have not been published previously. Lo
ngterm follow-up of some of the patients is described, and an overview
of the literature is given. (C) Chapman & Hall Ltd.
