Spondyloperipheral dysplasia (SPD; OMIM 271700) is an autosomal dominant connective tissue disorder characterized by vertebral body abnormalities (platyspondyly, end-plate indentations), hip dysplasia and brachydactyly type E. Here, we identified a novel truncating mutation (p.Lys1444AsnfsX27) in the C-propeptide of type II collagen in an affected Chinese individual with SPD. Our findings will provide clues to the phenotype–genotype relations and may assist not only in the clinical diagnosis of SPD but also in the interpretation of genetic information used for prenatal diagnosis and genetic counseling.
