Traditionally, the high costs and enormous expenditure of time associated with DNA sequencing has allowed an examination of only a few genes at a time for a given patient. Using this approach, the causative gene mutation can be very difficult to find in clinically diagnosed patients with a suspected genetic disease.

For this reason, CeGaT developed Diagnostic Panels to enable accurate diagnosis and optimal treatment for patients, without the limitations of traditional DNA sequencing and analysis. CeGaT’s Diagnostic Panels take advantage of next-generation sequencing technologies, which facilitate the process of simultaneously analyzing all known genes associated with a certain disease. This represents a significant advantage in the diagnosis of genetic diseases.

One of the unique features of CeGaT’s Diagnostic Panels is our “large panel approach”. Each time a panel is ordered, we sequence the primary genes on that disease-specific subpanel as well as all genes known to be associated with that type of disorder. If a primary clinical diagnosis cannot be confirmed from the subpanel, we then have the ability to look at the additional genes that were sequenced without having to go back and perform another test. Our experts work closely with the treating physician to determine the need for a secondary analysis. We believe this approach enhances the probability of finding the causative mutation in a patient and confirming a diagnosis.

A final medical report is issued to the ordering physician that contains detailed information about genetic variants detected in the panel. All variants are validated by Sanger sequencing in the laboratory. Our diagnostic team interprets the variants according to the most current scientific findings and literature.

The purpose of our Diagnostic Panels is to pinpoint the genetic cause of a disease within an affected patient or family. This enables us to:

  1. secure a clinical diagnosis
  2. offer a targeted investigation of other family members
  3. allow early therapeutic intervention
  4. make a prognostic assessment of the disease
  5. lay the basis for long term new therapeutic approaches.

Currently, we have 188 different diagnostic subpanels for diseases listed below. As noted, we perform the initial targeted evaluation on the subpanels but we always simultaneously sequence all of the genes associated with the particular disease area. For example, we sequence all 350+ genes associated with epilepsies and migraines if an epilepsy subpanel is ordered.

Diagnostic Panel Processing

For each Subpanel we perform the following steps:

  1. Preparation: Enrichment of DNA sample with a custom CeGaT-designed kit
  2. Sequencing: Massive parallel sequencing of all genes on the subpanel using next-generation sequencing (HiSeq or MiSeq)
  3. Bioinformatic evaluation: Potential disease-causing variants and under-represented gene regions are identified
  4. Validation of variants: Variants and underrepresented regions are sequenced and validated using the gold standard Sange Sequencingas an independent confirmation method
  5. Final bioinformatics and clinical evaluation of the complete Single Nucleotide Variant lists of all genes
  6. Medical report issued to ordering physician
