IAB Exome

IAB Exome

The IAB Exome represents a cost-effective alternative to whole-genome sequencing. This solution targets clinically relevant exome regions, allowing the identification of rare variants at a high level of uniformity. Exome sequencing is beneficial for studies focused on cancer, complex diseases, rare diseases, or Mendelian disorders or human population studies. The IAB Exome sequencing service offers affordable and at the same time high-quality results generated by using Human Core Exome Kit, Twist Biosciences, and sequencing platform NovaSeq 6000, Illumina.

The experienced team follows IAB Exome workflow with the strict quality procedures to perform the essential QC steps on your samples and generate reliable and repeatable results. A customized workflow is available.
