Whole Exome Sequencing

Our DNA is like letters-on-a-string - a very long string. Regions of DNA that code for certain diseases, like cystic fibrosis or sickle cell anemia, are called GENES. In the letters-on-a-string for each GENE are letters that make up important words - these regions are called EXONS. The total number of EXON regions is about 1.5% of our total DNA but they are linked to more than 80% of known genetic diseases. When we read regions of DNA in the exons, we call this an WHOLE EXOME SEQUENCING (WES). An WES is one of the most efficient ways to scan for the majority of genetic diseases.
