Congenital hearing disorders are among the most common impairments in newborns. About half of these hearing disorders are attributed to a genetic cause. Untreated or unnoticed hearing loss or deafness can cause severe speech impairment, developmental delays, or impaired social behavior. Therefore, it is critical for development that a diagnosis be made as early as possible. Hearing disorders can manifest at any age and always require a robust diagnosis and the best care. Our Diagnostic Panel for Hearing Loss provides accurate, short-term, and wide-ranging genetic diagnostics for non-syndromic and syndromic hearing disorders.
The Diagnostic Panel for Hearing Loss is based on exome sequencing with CeGaT ExomeXtra®. CeGaT ExomeXtra® covers all protein-coding regions as well as all known pathogenic intronic and intergenic variants. It thus provides the best basis for genetic diagnostics.

What We Offer with the Panel for Hearing Loss
Our Promise to You
* Due to high demand and a large number of urgent and prenatal cases, our turnaround time is currently slightly increased. For urgent samples, our processing time will of course remain 2-3 weeks.
Your Benefits
It is possible to request single or multiple predefined gene sets. In addition to the complete analysis of the genes of the requested gene set, we extend the analysis by additional genes for differential diagnosis. We report variants of unknown significance (ACMG class 3) and pathogenic and probably pathogenic variants (ACMG classes 4 and 5) for the primarily ordered gene set. For the genes included due to differential diagnosis, we restrict the reporting to pathogenic and probably pathogenic variants (ACMG classes 4 and 5), which could be related to the indication of the person seeking advice.
The Diagnostic Panel for Hearing Loss is based on the CeGaT ExomeXtra® enrichment. This allows, without additional sequencing, phenotypically eligible gene sets of other CeGaT panels or single genes to be additionally ordered. If you would like to assemble an individual panel, please feel free to contact us. We will be happy to support you.
In addition to the primary diagnostic assignment, the assessment of ACMG genes and pharmacogenetic profiling may also be ordered.
Method
The enrichment of the coding regions and the adjacent intronic regions is performed using an in-solution hybridization technology. The selection of the targeted regions and the design of the enrichment baits is performed in-house. High throughput sequencing is performed on Illumina platforms. Bioinformatic processing of the data is achieved using an in-house computer cluster.
Following data processing, our team of scientists and specialists in human genetics analyze the data and issue a medical report.

ACMG Genes
Genetic variation may sometimes be identified, which does not fit within the scope of the requested genetic analysis (so-called secondary findings). The reporting of these variants is limited to pathogenic alterations (ACMG classes 4 and 5) within selected genes, for which a treatment or course of action exists for you or your family (according to the current guidelines of the American College of Medical Genetics and Genomics; details on genes and associated diseases can be found here.
Pharmacogenetics
Pharmacogenetic analysis detects genetic changes that affect the effectiveness of drugs. Genetic variants that affect proteins responsible for the metabolism of substances can significantly change their tolerance and efficacy. These drugs include, among others, antidepressants, pain relievers, neuroleptics, chemotherapeutics, AIDS drugs, thrombosis drugs, anesthetics, beta-blockers, or statins.
The reduced activity of a specific enzyme can lead to an increased drug level in the standard dosage, which is often associated with undesirable side effects. With drugs that are only activated by metabolism, the therapeutic effect can be completely absent. Likewise, due to the resulting increased rate of degradation of the medicinal substance, an increased enzyme activity leads to inadequate effectiveness of the therapy.
The pharmacogenetics option analyzes known variants in 22 genes involved in the metabolism of drugs. If specific gene variants occur, the treating doctor can adapt the therapy individually. The pharmacogenetic analysis can minimize serious side effects and helps to avoid failure of the treatment.
