Asper Otogenetics

Sensorineural hearing loss testing panels are now included into Asper Otogenetics portfolio, which also contains tests for diagnostics of numerous syndromes related to sensorineural and conductive hearing loss. Our multi-gene panels provide clinicians valuable tool for accurate differential diagnosis of syndromes with a similar phenotypic spectrum.

Updated version of Sensorineural Hearing Loss test

Asper Biotech has updated Sensorineural Hearing Loss (SNHL) genetic test. The new version includes five additional genes – KCNQ4, TCM1, MYO15A, MYO7A, as well as 232kb deletion from GJB6 gene [del(GJB6-D13S1854)]. Now the SNHL microarray covers the analysis of 11 genes – GJB2, GJB6, GJB3, SLC26A5, SLC26A4, MTNR1, MTTS1, KCNQ4, TCM1, MYO15A, MYO7A – and detects 246 mutations instead of 198 of the earlier version.

Indications for genetic testing:

  1. Confirmation of clinical diagnosis
  2. Determination of molecular genetic basis both of nonsyndromic and/or syndromic SNHL
  3. Distinguish different forms of nonsyndromic hearing loss and deafness
  4. Define etiology of hearing loss after aminoglycoside therapy
  5. Detection the carrier status of individuals with family history of maternally-inherited hearing loss with or without aminoglycoside therapy
  6. Detection the carrier status of relatives with a known mutation
  7. Genetic counseling
  8. Prenatal diagnosis

Hereditary sensorineural hearing loss (SNHL) includes syndromic and non-syndromic forms. The syndromic forms of SNHL include Usher syndrome, Pendred syndrome, Waardenburg syndrome, Jervell and Lange-Nielsen syndromes, etc. Most cases of SNHL are nonsyndromic. SNHL can follow a pattern of autosomal dominant, autosomal recessive, x-linked recessive, or mitochondrial inheritance.
