What is exome sequencing?
Exome sequencing is a technique that is used to cover the human exome. More about Exome sequencingWhat is exome sequencing?
Rater than be limited to analysing single genes, or predefined panels of genes, exome sequencing is aimed to cover the human exome, the coding region of all (20000) human genes. All types of mutations are potentially detectable by this assay. Due to this, exome sequencing has proven to be a diagnostic test with a very high diagnostic yield.Advantages of exome sequencing:
- The diagnostic yield of exome sequencing is higher than achieved by Sanger sequencing
- Exome sequencing can solve complex clinical cases
- Exome sequencing can lead to a quicker genetic diagnosis
Our exome sequencing approach:
Exome Sequencing Diagnostics has been developed and implemented in our Genome Diagnostics laboratory in 2011, in close collaboration with clinicians, clinical laboratory geneticists and scientists. In an initial phase, the test was focused on the 5 specializations of our laboratory, but rapidly expanded to other disorders. Since 2011 we have processed over 10000 clinical exome requests. Our current sample load exceeds 500 samples per month.
Our Exome sequencing Diagnostics consists of 3 major steps:
- Exome Sequencing
- Exome Data Analysis
- Clinical Interpretation & Reporting
