Postaxial polydactyly-dental and vertebral anomalies syndrome is a rare, genetic, developmental defect during embryogenesis syndrome characterized by postaxial polydactyly and other abnormalities of the hands and feet (e.g. brachydactyly, broad toes), hypoplasia and fusion of the vertebral bodies, as well as dental abnormalities (fused teeth, macrodontia, hypodontia, short roots). There have been no further descriptions in the literature since 1977.
