Whole-Exome Sequencing

What Is the Exome?

Exons are the sections of the genome that are transcribed into mRNA and translated into proteins. Altogether, the exons make up the exome — about 2% of the total genome.

It is a preferred tool for understanding patient health histories and diagnoses, as well as testing at-risk family members.

Why Is Studying the Exome Important?

Most (about 85%) of known genetic variants that contribute to disease occur in the exonic regions.

Through a gene sequencing approach targeting this relatively small percentage of the genome, scientists can learn about the majority of clinically relevant genetic variations that affect protein coding.

What Can You Do?

Maximize Your Budget

Sequence ~2% of the genome and study ~85% of known genetic variants.

Find Rare Variants

Rely on Psomagen's CLIA-validated protocols for WES at 50x minimum coverage.

Process Clinical Samples

Discover rare transcripts more easily with the greater depth and coverage afforded by sequencing far less DNA than WGS.

Offer Precision Medicine

Introduce new ways to prevent, diagnose, and treat disease on a personalized level.
