Abstract: | A 9-year-old boy from an incestuous union presented with mild clinical and roentgenological manifestations of pseudoachondroplasia. Tibial growth cartilage was obtained during a routine orthopedic procedure. Microscopic, histochemical and biochemical analysis showed changes identical to those of 6 sporadic cases of typical pseudoachondroplasia. The results support a concept of pathogenetic homogeneity of pseudoachondroplasia.Dedicated to Prof. Dr. H.-R. Wiedemann on the occasion of his 65th birthday |
