WES identified two variants in the OTOF gene (NM_001287489.2), which are associated with autosomal recessive non-syndromic auditory neuropathy (AUNB1), including temperature-sensitive auditory neuropathy (TS-ANSD), as well as prelingual mild-to-profound sensorineural hearing loss (DFNB9; MIM: #601071) [40]. Here, OTOF is linked to auditory neuropathy.
