#374 The Eras of Genetic Testing: From the Human Genome Project to Precision Medicine

What if we looked at genetic testing not just as a tool, but as a story unfolding through eras of innovation, access, and personal meaning?

To explore the genetic testing landscape over the last couple decades we are joined by a fellow podcaster Rome Madison, who is also a precision medicine expert and longtime industry leader with extensive experience working in diagnostics and precision medicine.

Rome has trained sales teams, helped launch groundbreaking cancer diagnostics, and now hosts Genetics for Healthcare: A Podcast for Patients. He’s here to share not only how genetic testing has evolved across different eras, but also his personal connection to the field and why he’s committed to ensuring patients benefit from the genomic revolution.

On This Episode, We Discuss:

Setting the Stage: Rome’s Personal Journey

• How Rome entered the genetics and diagnostics space shortly after the Human Genome Project
• What motivates his continued work at the intersection of innovation, patients, and access
• Why confidence, curiosity, and communication matter in fast-changing scientific fields

The Early Era: Post–Human Genome Project

• What diagnostics felt like in the early 2000s
• Early pharmacogenomics and predicting chemotherapy response
• Barriers to adoption, including cost, infrastructure, and skepticism

The Growth Era: Expansion of Genetic Testing

• How cancer diagnostics and precision medicine began shaping standard care
• Shifts in how clinicians and patients talked about risk and prevention
• Lessons learned about equity, access, and unmet expectations

The Current Era: Precision Medicine Goes Mainstream

• What distinguishes today’s genetic testing landscape from earlier eras
• Ongoing challenges around affordability, access, and education
• The role of podcasts and science communication in empowering patients

Looking Ahead: The Next Era of Genetic Testing

• What might define the next wave: RNA, epigenomics, microbiome, multi-omics
• Where AI and advanced data analytics fit into future care models
• Why collaboration across pharma, diagnostics, advocacy groups, and patients is essential
• Whether population-wide genetic testing could become routine in the years ahead
