Given the failure to show any link with the previously reported ANSD genes such as OTOF (NM_194248, 2p23.3) (28), DIAPH3 (NM_001042517, 13q21.2) (29), SLC17A8 (NM_139319, 12q23.1) (30), AIFM1 (NM_004208, Xq26.1) (31), OPA1 (NM_130837, 3q29) (32), and an ANSD gene reported by us, ATP1A3 (NM_152296.4, 19q13.2) (33), we suspected an involvement of another gene. Here, DIAPH3 is linked to auditory neuropathy.
