Crane-Heise Syndrome
Crane-Heise syndrome is a very rare syndrome characterized by poorly mineralized calvarium, facial dysmorphism, vertebral abnormalities and absent clavicles.
Epidemiology
Nine cases have been reported in the literature so far.
Clinical description
Dysmorphic features include micrognathia, cleft palate, hypertelorism and upturned nares. Clavicular aplasia is constant and agenesis of cervical vertebral bodies is frequent. Intra uterine growth retardation is constant.
Etiology
It is most likely that the condition is hereditary, transmitted as an autosomal recessive trait.
Antenatal diagnosis
Antenatal diagnosis is possible by ultrasonographic monitoring for cerebral and vertebral malformations.
Prognosis
Prognosis is poor; the syndrome is almost always lethal soon after birth.
