Stickler syndrome

Stickler syndrome is a heritable disorder of connective tissue characterized by ocular, craniofacial, and musculoskeletal manifestations, as well as hearing loss. Ocular features include high myopia, congenital vitreous anomalies, cataracts, and retinal detachment. Mid-facial hypoplasia, micrognathia, and cleft palate may be present, and a diagnosis of Stickler syndrome is established in approximately 10-20% of individuals with Robin sequence. Hearing impairment of variable severity is present in 40% of individuals with Stickler syndrome. Skeletal involvement may manifest as early-onset osteoarthritis, relative short stature, joint hypermobility, and scoliosis/kyphosis; radiographic features include mild spondyloepiphyseal dysplasia and platyspondyly. Variable expressivity in affected individuals is observed both within and between families, though the ocular phenotype tends to be consistent within families. In addition, both ocular-only and non-ocular forms of Stickler syndrome are described.
