Three things every healthcare professional should know about genomic medicine
Therese Ingram Nissen
Christine is a medical actor helping to train the next generation of healthcare providers. She is also a real patient with a high familial risk for Lynch Syndrome. But that is not her only problem; her doctor did not know enough about this genetic disorder to spot the red flags in her family history. Nor did he know what to do with her aunt's genetic test results that identified a mutation associated with Lynch.
How did Christine discover her risk? Coincidently, she just happened to be portraying a patient with a similar familial risk at The Jackson Laboratory's Clinical and Continuing Education Cancer Genomics Workshop for primary care providers.
Unfortunately, her doctor's lack of genomic knowledge is not unique. Most medical schools spend little time teaching about genetics and genomics. It is no wonder that many healthcare professionals report that they feel unprepared and lack confidence talking about genomics with their patients. To complicate matters, healthcare professionals are faced with a crowded landscape of concerns and up until recently, genomics lacked the evidence necessary to make it useful in the clinic.
Today, new advances in personalized medicine have increased the number of tests that have clinically actionable results, especially in the treatment and diagnosis of cancer.
What should healthcare professionals do to incorporate genomic medicine into patient care?
Intake forms rarely provide enough information to accurately determine risk. There are many different approaches to collecting family history information. Recording information in a pedigree can help you visualize patterns of disease more easily, which is one reason genetics experts prefer them. There are also online tools available that allow patients to input their family history information at home and print it out for you to review. Find a tool that helps you collect sufficient information and update it, as family history information changes over time.
2. Recognize the patterns and red flags in the family history that put your patients at increased and high risk for disease including:
Family history of multiple affected family members with the same of related disorders
Earlier age at onset of disease than expected
Condition in the less-often-affected sex (e.g., breast cancer in a male, autism in a female)
Disease in the absence of known risk factors (e.g., lung cancer in a non-smoker)
Ethnic predisposition to certain genetic disorders (e.g. breast cancer in Ashkenazi Jewish population)
Genetic counseling integrates risk assessment, education and counseling. In some cases, it includes the offer of genetic testing, decision-making support and interpretation of results. You should be able to prepare high-risk patients and families for what to expect, communicate relevant information to the genetics team, and follow up with the patient after genetic services have been provided. Those health professionals who choose to provide genetic counseling services to their clients should be able to perform all components of the process set out by the National Society of Genetic Counselors including:
Taking a detailed medical and family history
Provide risk assessment and risk counseling
Address psychosocial issues and emotional concerns
Direct an in-depth consent process for genetic testing, when applicable
Disclose results of genetic testing, when applicable
Determine and communicate screening and management plans
Summarize and plan for follow up
For more education about genomics for health professionals here are some quality resources:
Clinical and continuing education at JAX (formerly National Coalition for Health Professional Education in Genetics) Resources and tools, short online courses that are interactive and case-based in addition to in person workshops targeted to primary care providers and cancer.
G2C2 A peer-reviewed competency-based resource clearing house.
GEC-KO resources and online education for all health care providers from Canada.
