title: The severe recessive form of pseudoachondroplastic dysplasia.
abstract: Genetic and clinical heterogeneity within the category of pseudoachondroplastic dysplasia is discussed. Clinical and radiological findings are presented in a family where 4 out of 7 siblings, aged between 3 and 10 years, had a severe form of the condition. The parents had short stature without any signs of pseudoachondroplastic dysplasia. Inheritance in this family appears to be recessive, with a possibility that the abnormal allele may be partially manifest in heterozygotes.
