Multiple epiphyseal dysplasia (MED) is one of the more common skeletal dysplasias. MED is characterized by joint pain and stiffness, a waddling gait, and/or mild short stature in childhood. Radiographic findings include delayed and irregular ossification of the epiphyses in multiple joints. Mutations in at least six different genes (COMP, MATN3, COL9A1, COL9A2, COL9A3, and DTDST) can cause MED, and it can be either dominant or recessive inheritance. Molecular diagnosis is important for accurate prognosis and genetic counselling. COMP mutation is the most common form of MED in Western. But, MATN3 mutation was reported as the most common type of MED in Korea. Here, we describe a boy who was diagnosed as MED by clinical and radiological features. Hip radiograph of the patient was suggested MATN3 mutation. But knee radiograph was suggested COMP mutation. MATN3 and COMP mutations direct sequencing, but were no mutation. So we tested whole exome sequencing, but significant variant was not detected as known MED six genes mutations. The patient was diagnosed as having MED clinically and radiologically. Further study to identify the other responsible genes for MED is needed.
