TMTC2 and auditory neuropathy: Our sequence analysis of individuals S60 and S61 did not uncover any nonsynonymous variants in genes already known to be associated with ANSD such as autosomal recessive OTOF (Yasunaga et al., 1999) and PJVK (Delmaghani et al., 2006), and autosomal dominant AUNA1 (Kim et al., 2004), leaving rs35725509 in the TMTC2 gene as the likely causal mutation.
