otoferlin, OTOF, DFNB9
Mutations in this gene are a cause of neurosensory nonsyndromic recessive deafness, DFNB9. The short form of the encoded protein has 3 C2 domains, a single carboxy-terminal transmembrane domain found also in the C. elegans spermatogenesis factor FER-1 and human dysferlin, while the long form has 6 C2 domains. The homology suggests that this protein may be involved in vesicle membrane fusion. Several transcript variants encoding multiple isoforms have been found for this gene.

Papers on otoferlin
Thyroid hormone is required for the pruning of afferent type II spiral ganglion neurons in the mouse cochlea.
Mustapha et al., Stanford, United States. In Neuroscience, Feb 2016
Using a transgenic approach to specifically label type II spiral ganglion neurons (SGNs), we found that lack of TH causes persistence of excess type II SGN connections to the OHCs, as well as continued expression of the hair cell functional marker, otoferlin (OTOF), in the OHCs beyond the maturation period.
Temperature Sensitive Auditory Neuropathy.
Wang et al., Beijing, China. In Hear Res, Feb 2016
Genetic analysis revealed that these three patients had otoferlin (OTOF) homozygous or compound heterozygous mutations with the genotypes c.2975_2978delAG/c.4819C>T, c.4819C>T/c.4819C>T, or c.2382_2383delC/c.1621G>A, respectively.
Ferlins show tissue-specific expression and segregate as plasma membrane/late endosomal or trans-Golgi/recycling ferlins.
Cooper et al., Sydney, Australia. In Traffic, Jan 2016
In humans, dysferlin mutations cause limb-girdle muscular dystrophy (LGMD2B) due to defective Ca(2+) -dependent, vesicle-mediated membrane repair and otoferlin mutations cause non-syndromic deafness due to defective Ca(2+) -triggered auditory neurotransmission.
Audibility, speech perception and processing of temporal cues in ribbon synaptic disorders due to OTOF mutations.
Starr et al., Padova, Italy. In Hear Res, Dec 2015
Mutations in the OTOF gene encoding otoferlin result in a disrupted function of the ribbon synapses with impairment of the multivesicular glutamate release.

Wichmann, Göttingen, Germany. In Hear Res, Dec 2015
Cochlear inner hair cell ribbon synapses exhibit a unique one-to-one relation of the presynaptic active zone to the postsynaptic cell and use hair-cell-specific proteins such as otoferlin for vesicle release.
