For certain patients the combination of symptoms does not allow the clinician to pinpoint a potential diagnosis. In such challenging cases, often a stepwise diagnostic strategy is chosen, which makes the testing complex, time consuming, costly and often not even conclusive. Furthermore, a delayed diagnosis may have a significant impact on the patient’s treatment and quality of life.
For these cases, the use of broad, whole exome sequencing (WES) has advantages over initially more targeted genetic testing. Whereas such targeted genetic testing focuses on a single gene or on a limited set of predetermined genes, WES testing examines all the protein coding regions in the genome (exons) simultaneously. It is estimated that most of the disease-causing mutations (about 85%) are located within the exons. This lack of bias allows to also identify disease causing mutations in unexpected genes that would be missed by targeted approaches.
CentoXome®, CENTOGENE’s whole exome sequencing service, offers an accurate and cost-effective one-step solution, with high diagnostic yield.
