Abstract
- Stickler syndrome is a very rare connective tissue disorder. The authors of the present study describe an 11-month-old girl with high myopia, retinal abnormalities, flat nose, cleft palate, retrognathia, micrognathia, short stature and arthrogryposis. Radiological evaluation also showed irregularity of the epiphysis of the femur and tibia and spondyloepiphyseal dysplasia. Genetic analysis using a peripheral blood sample revealed a novel variant c.787G>A (p.Gly246Asp) mutation of the COL2A1 gene. This is the first Korean case with Stickler syndrome confirmed by genetic testing.
