Mild spondylar dysplasia, delayed epiphyseal ossification of the hip and knee, and severe brachydactyly with cone shaped phalangeal epiphyses are characteristic features. In adulthood, premature spondylosis and degenerative joint disease develop in some patients. Frequent respiratory infections with prolonged cough and inspiratory stridor, consistent with laryngomalacia, can also be present.
