Testing strategy


The OtoGenomeā„¢ Test is best suited for individuals who have a diagnosed hearing loss for which an underlying etiology has not yet been identified. For an individual with apparently non-syndromic hearing loss, this panel covers both non-syndromic causes of hearing loss as well as those which can present as non-syndromic. Onset of features associated with a syndromic type of hearing loss can be delayed or variable. Given the genetic heterogeneity of hearing loss, the OtoGenomeā„¢ Test allows for a shortened diagnostic course by analyzing 110 genes in a single test. A number of subpanels are available for individuals with a diagnosis or clinical suspicion of a specific hearing loss phenotype or syndromic condition, such as auditory neuropathy spectrum disorders, Usher syndrome, Pendred syndrome or hearing loss with EVA, Branchio-oto-renal syndrome, Waardenburg syndrome, or Wolfram syndrome.
