AIFM1 and auditory neuropathy: In 2006, we reported a large Chinese family with X-linked progressive auditory and peripheral sensory neuropathy, and mapped this ANSD locus (AUNX1) to chrXq23-27.3.10 Using whole-exome sequencing (WES), we have identified the causal AUNX1 gene as AIFM1 and show that variants in this gene are a common cause of familial and sporadic ANSD.
