  1. Isolated MD group: Patient 1 had only one mutation and patient 2-28 had no mutation in SLC26A4. IEM group: Patient 29, 30 had one mutation and patient 31-44 had no mutation in SLC26A4. EVA group: Most patients had bi-allelic mutations except Patient 45, 81, 85 had one mutation and patient 83 had no mutation in SLC26A4. EVA with MD group: Most patients had bi-allelic mutations except Patient 132, 138, 139 had one mutation and patient 95 had no mutation.
