Lecture 20: Practical Genomic Medicine

TL;DR

The implementation of genomic medicine brings several challenges, including the need for trained personnel, data management, and lack of widespread knowledge among healthcare professionals.

Transcript

ISAAC SAMUEL KOHANE: So what we'll talk about today is a very practical genomic medicine, by which I mean not only stuff that we think is going to be imminent in two years but what it means today to do genomic medicine, nothing future, just today. And if you think that I have stepped across a line into the future, call me on it. So let's talk about... Read More

Key Insights

• 🖤 The implementation of genomic medicine is hindered by a lack of trained personnel and difficulties in data management.
• 😷 Patients are driving the demand for genetic testing, but the medical system is unprepared to handle this demand.
• 😷 The role of a medical genomicist is necessary but currently lacking in the medical field.

Questions & Answers

Q: Why has genomic medicine not had the immediate impact that was expected?

One reason is the lack of trained personnel who can effectively utilize genomic information in their practice. Additionally, the medical system is not equipped to handle the large amount of data generated by genomic testing.

Q: What factors affect the ordering of genetic tests by physicians?

Factors that affect ordering include cost, the ability to interpret test results, and patient demand. Physicians are more likely to order genetic tests if they feel comfortable with interpreting them and if the patient requests it.

Q: What are some potential solutions to the challenges of genomic medicine?

Possible solutions include the use of internet-enabled triage specialists, the training of primary care physicians in genomics, and the development of simplified reports and decision support tools.

Q: What are the implications of genetic testing for patients?

Genetic testing can have both positive and negative implications for patients. It can provide valuable information about disease risk and guide treatment decisions. However, it can also lead to false positives and unnecessary interventions.

Summary & Key Takeaways

• Genomic medicine was expected to have an immediate impact on human disease and medicine, but the reality is that it has not yet met these expectations.

• Difficulties in the diffusion of genomic medicine include a lack of trained personnel and challenges in data management.

• The role of a medical genomicist is necessary to bridge the gap between genetics and general medicine, but the medical system is not currently equipped to handle this.
