Du Pan type chondrodysplasia (DPC) represents the milder end of homozygous growth differentiation factor 5 (GDF5) disorders. We report on a 20-month-old child with complex brachydactyly and mild proximal fibular hypoplasia, consistent with DPC, in the absence of other anomalies of long bones and joints. Mutational analysis disclosed two novel GDF5 mutations within the protein's mature domain and in the cleavage site of the prodomain which explains the distinct DPC phenotype found in this patient. The unaffected mother and the father who presented with mild brachybaso/ mesophalangy of all digits were both heterozygous carriers.
