[Sublethal microcephalic chondrodysplasia. Taybi-Linder syndrome, primordial microcephalic nanism types I and III].

The authors describe a case of microcephalic dwarfism observed in a newborn until 10 months of age and discuss the diagnostic challenge. They show that the Taybi-Linder syndrome and the primordial dwarfism type I and type III of Majewski are an identical recessive autosomal entity. The radiological evolution explains the initial separation of type I and type III. Because of the skeletal lesions, lacking in the Seckel syndrome, the name of sublethal microcephalic chondrodysplasia is proposed for this disease.
