Background: Multiple epiphyseal dysplasia (MED) is a heterogeneous genetic condition characterized by variable phenotypes, such as short stature (mild to moderate), joint deformities, abnormal gait, scoliosis, and brachydactyly. Recessive mutations in the SLC26A2 gene cause a phenotype of multiple epiphyseal dysplasia-4 (MED-4). In the present study, we identified novel compound heterozygous mutations in the SLC26A2 gene in a Chinese family with two affected sibs with MED-4. Case presentation: Radiographs revealed hip dysplasia, brachydactyly and scoliosis in patient 1. Radiological examinations in patient 2 also showed hip dysplasia recently. Both of them were diagnosed with MED-4. SLC26A2 c.824 T > C and SLC26A2 c.1198C > T were identified in two siblings in this family, which were inherited from both parents, one mutation from each. Conclusions: This is the first Chinese MED-4 family attributed to SLC26A2 mutations, and these results show that these novel compound heterozygous mutations in SLC26A2 contribute to MED-4.
