Summary
What is the value of someone’s genome over their life? Is a genome today what it was 10 years ago? How does the adoption of genomic testing compare to other areas in medicine, such as imaging or electronic health records? Today we take a pretty comprehensive look at genomic testing in practice with Damon Hostin, Head of Market Access, Clinical Solutions at Illumina. Damon brings a rare perspective to this conversation. He’s been in the field since the Celera era, when sequencing was helping define modern genomics, and he’s also worked on the front lines in a large community health system, CommonSpirit Health. At Illumina, he speaks regularly with payers and other stakeholders. Across oncology, rare disease, reproductive health, and pharmacogenomics, Damon describes a field that has clearly moved into standard of care in key areas—but is still very much in the phase of identifying the “eligible but under-tested.” Adoption is real, but it’s incomplete.

Its value compounds over time as databases grow, variants are reinterpreted, and new therapies emerge. At the same time, even the basic notion of what a “genome” is, is beginning to shift. With the rise of multi-omic data—transcriptomics, proteomics, methylation—the question is no longer just cost per genome, but what kind of biological insight we’re actually measuring. “A genome isn’t a genome isn’t a genome,” Damon says. He ends with a line that neatly reframes the entire debate arou…
