Invitae research highlights utility of proactive genetic screening, importance of assessing secondary findings in genetic testing
CHARLOTTE, N.C., April 10, 2018 /PRNewswire/ -- Researchers from Invitae Corporation (NYSE: NVTA), one of the fastest growing genetic information companies, will present findings showing proactive genetic health screening reveals medically significant findings for a substantial portion of patients, and looking for secondary findings during genetic testing provides a substantial yield of actionable risk factors for disease. The studies are among the company's data being presented this week at the American College of Medical Genetics (ACMG) annual meeting in Charlotte, NC.
Healthy individuals are increasingly seeking genetic testing to identify their personal risks for inherited conditions such as cancer and cardiovascular disease. An analysis of 1,300 patients tested with a diagnostic-grade genetic screening panel designed for healthy adults found clinically actionable results in 16 percent of patients, predominantly in genes associated with an elevated risk for cancer or cardiovascular disease.
"Healthy adults are increasingly interested in using genetic information to understand their risk of disease and these data show that interest is warranted. But it is essential that consumers receive medically sound testing to assess their risk of diseases like cancer where monitoring and early intervention can be helpful," said Robert Nussbaum, M.D., chief medical officer of Invitae. "Talking about genetic screening with a physician or genetic counselor and then using the highest quality testing can help ensure people receive accurate results and, just as importantly, sound medical advice on how to respond to those findings."
Invitae's proactive genetic tests are currently being provided at a number of institutions enabling clinicians to use this type of genetic screening with patients in a variety of clinical settings, including primary care.
In another platform presentation at the meeting, researchers from the company are reporting on an analysis of the frequency of actionable variants in hereditary cancer syndrome genes found in more than 3,000 patients referred for testing for hereditary cardiovascular disorders. Under an IRB-approved protocol that allowed review of de-identified test data, the researchers analyzed genetic testing results for a number of well-known genes associated with increased cancer risk in patients with no known indication for hereditary cancer gene testing. The researchers found that six percent of patients had pathogenic variants in clinically actionable hereditary cancer genes.
"Current ACMG guidelines on secondary findings support providing such information regardless of the original indication for testing," said Dr. Nussbaum, one of the authors of the study. "Our study indicates that one in 16 individuals could receive actionable information from hereditary cancer gene testing even in the absence of personal or family history that would suggest the need for a diagnostic evaluation of cancer risk. The results suggest the importance of screening for medically actionable gene mutations regardless of original indication."
