2. How to provide a timely and accurate diagnosis?
Genome sequencing allows us to diagnose
1000s of genetic conditions with a single test
But it’s not really a single test, it’s thousands
or millions of them, all in parallel
We need to know which are relevant to the patient’s
condition
3. Labs frequently have to re-contact the ordering clinician to get more
detailed information
— GeneDx XomeDx
— Invitae Exome
The patient phenotype drives genomic diagnostics
