How Does WES Work?
1
DNA Isolation
DNA is extracted and purified from your blood or saliva sample.
2
Exome Capture
Protein-coding regions are targeted with specific probes.
3
Sequencing
High-accuracy sequencing on the Illumina NovaSeq platform.
4
Analysis & Report
Variants are classified and reported according to ACMG guidelines.
WES vs WGS Comparison
✅ WES (Whole Exome)
- • ~20,000 gene coding regions (~1-2% genome)
- • Lower cost
- • Faster analysis and interpretation
- • Covers 85% of known disease variants
WGS (Whole Genome)
- • Entire genome (~3 billion base pairs)
- • Higher cost
- • Longer analysis time
- • Includes non-coding region variants
