Dueling BRCA Databases: What About the Patient?

The news release Monday morning grabbed my attention:

“Study finds wide gap in quality of BRCA1/2 variant classification between Myriad Genetics and a common public database.”

Myriad Genetics had been exclusively providing tests, for $3000+ a pop for full BRCA gene sequencing, for 17 years before the Supreme Court invalidated key gene patents back in 2013. Since the ruling a dozen or so competitors have been offering tests for much lower prices. Meanwhile, Myriad has amassed a far deeper database than anyone else, having been in the business so much longer. And it’s proprietary.



Public databases of variants of health-related genes have been around for years too. The best known, ClinVar, collects and curates data from the biomedical literature, expert panels, reports at meetings, testing laboratories, and individual researchers, without access to Myriad’s database. ClinVar uses several standard technical criteria to classify variants as “pathogenic,” “benign,” or “of uncertain significance.” (“Likely pathogenic” and “likely benign” were used more in the past.)

ClinVar lists 5400 variants just for BRCA1. The criteria come from population statistics, how a particular mutation alters the encoded protein, effects on the phenotype (symptoms), and other information. Bioinformatics meets biochemistry to predict susceptibility. The BRCA1 protein acts as a hub of sorts where many other proteins that control DNA repair gather. DNA Science discussed the genes behind breast and ovarian cancers here.

As gene sequences accumulate in the databases and troops of geneticists and genetic counselors annotate them, the proportion of pathogenic and benign entries will increase as that of the unsettling “variants of uncertain significance” — VUS — will decrease. Knowing will outpace not knowing. In the meantime, a woman with a VUS for a gene that confers susceptibility to develop breast and/or ovarian cancer, concerned that her DNA sequence isn’t “normal,” might have her at-risk organs removed. And then she might learn, as the databases grow, that her variant is really benign after all, because while she was being treated for a disease that she didn’t actually have, more patients emerged who have the gene variant but not the related cancers.

The reclassification of a VUS as something more meaningful depends on access to as much information as possible.

How many unnecessary surgeries are happening? Have happened? Myriad estimates hundreds to thousands.


The news release announced a paper from Myriad just published in The Oncologist that compared 4,250 unique BRCA1 and BRCA2 gene variants in the company’s database to entries in ClinVar, and found that 26.7% of the ratings do not fully agree. (ClinVar lists multiple sources for many of the variants, and 14.5% didn’t agree on all counts and 12.3% on only some.) According to Myriad, most of the VUS listings were in ClinVar. In fact, only 0.5% of Myriad’s BRCA1 sequences and 1.1% of their BRCA2 sequences are VUS. They’re clearly ahead of the game.


A breast cancer cell (NHGRI).

The discordance isn’t really news. It echoes earlier reports both from Myriad researchers for the BRCA genes and from a  non-Myriad, multi-center group that also found 26% discordance, but their analysis included several cancer predisposition genes; the most conflicting were CHEK2 and ATM. And another recent study found that about half of women with VUS undergo bilateral mastectomy, concluding that “many surgeons managed patients with BRCA1/2 VUS the same as patients with BRCA1/2 pathogenic mutations.” That’s terrifying. It means that the problem isn’t due just to overanxious patients, but also to surgeons who might not be genetics-savvy.

The news release doesn’t go to the obvious conclusion, that privatization of the database may be fueling inappropriate surgeries, or at least not preventing them, a point that Sharon Begley made elegantly in Stat News. Many of her expert sources countered the implication that variant classifications from ClinVar are just accepted and delivered to patients without further and often intense research and validation by health care providers.


In the news release, William Gradishar, MD, from the Feinberg School of Medicine at Northwestern University and lead author on the new study from Myriad, provided the company view (slightly edited):

“The high degree of discordance seen in this study signals a cautionary note … it means that different labs are providing different results to patients for the same genetic mutation … some patients are receiving incorrect results that may have life-changing or -threatening implications… Although efforts are underway to resolve the quality problems within public databases, it is unlikely the issue will be resolved soon and users of public databases likely will continue to encounter discrepancies. At this time, labs should not use public databases in any way in clinical variant classification.”

Actress and activist Angelina Jolie had her breasts and ovaries removed to lower her risk of BRCA1-associated cancers.

Ron Rogers, spokesperson for Myriad, wrote in an email that the company provides database access for certain scientific collaborations, but then provided the business view:

“Myriad has invested hundreds of millions of dollars to develop our database over two decades, which is used to classify variants as part of the Company’s specific process. We encourage other commercial labs to make their own investments, which are required to offer a quality product. The problem is that some other commercial labs refuse to make the needed investments. Instead, they are trying to short cut the process by relying on inaccurate public databases, which has the potential to deliver inaccurate results and harm real people.”

If anyone remembers the race to sequence the first human genome, which pitted NHGRI and their public database against Celera Genomics and their proprietary one, the battle over BRCA is a little deja vu all over again.

Rogers added that if patients who have had bilateral mastectomies following a report of a VUS had come to Myriad, “we could have provided many of them with definitive answers and helped to prevent a significant number of these life-changing procedures.” About 85% of the BRCA testing market indeed uses Myriads products.

Myriad’s tests as well as their support (genetic counseling) are excellent. The company helped a friend of mine interpret and confirm BRCA1 test results from 23andMe, which her son had taken on a whim but the unexpected finding of a mutation had sent her family into a tailspin. 23andMe, the direct-to-consumer genetic information company, coaxes customers to provide their results for research (“Be part of something bigger”) and charges investigators for access to the data. Like Myriad, 23andMe also suffered a setback in 2013. FDA yanked some of their health-related carrier tests, but the agency reversed the ban on April 6, 2017.

23andMe and Myriad serve different types of individuals. Many of 23andMe’s customers, like my friend’s son, aren’t distraught over cancer, just curious and acting on their own. So here’s another comparison: Is Myriad’s protecting of their data similar to my reaction to people downloading my books for free? No. I’m just losing royalties.

My mother’s lost battle with breast cancer can’t help but influence my view that impeding accurate diagnosis for profit, to protect assets, may make sense in the business world but is not the right thing to do. I have trouble commoditizing patient tests and sequestering information that might help, and the many rock stars of genetics who have joined the Free the Data movement would agree.

Because the entire discussion makes me queasy, I thought instead I’d illustrate the distinction between a harmful mutation and a VUS, by comparing the BRCA1 gene sequence to the English language.


Most genes are thousands of DNA bases long, and therefore can vary in many ways. Gene variants – mutations – can affect health or not depending upon how they disrupt the proteins that they encode.

BRCA1 (the gene) is 125,951 bases long, only 5,589 of which are represented in the protein. Mutations near its ends are more damaging than those in the middle. One of the two Ashkenazi (Jewish) “founder” mutations, 185delAG, removes an A and a G at position 185, near the beginning. Because a gene sequence is read in triplets – every 3 DNA bases encodes an amino acid – adding or deleting a number that isn’t 3 or a multiple of it devastates the protein’s function. 185delAG is, then, a gene variant of very high significance. (My analogy below is not quite on target because the words in a sentence vary in length.)

I entered 125,951 letters into a publishing calculator that translates numbers of alphabet characters into a book of a particular size, and wound up with a 6” by 9” volume of 265 pages. That view of the BRCA1 gene’s enormity corresponds to approximately the length of Margaret Atwood’s dystopian masterpiece “The Handmaid’s Tale.” I’m rereading it, inspired by the “Make Margaret Atwood Fiction Again” signs at the March on Washington January 21.

I took a sentence about as far into the book as the 185delAG mutation is in the BRCA1 gene:

Everything except the wings around my face is red: the color of blood, which defines us.

Removing two adjacent letters – the “ex” in “except” – and then moving the other letters into the word-sizes, clearly disrupts the meaning:

Everything ceptth ewi ngsar oundmy fa ceis re dth: eco lorof bl oodwh ichde finesus

Gibberish, and it would continue to the end of the book. In a gene, the offset sequence would likely lead to a stunted protein, halted when reaching a “stop” signal in the mRNA. And when a BRCA1 gene loses meaning, control of DNA repair falters and other mutations go unchecked. Cancer results.

A VUS would do something less drastic, such as replacing a letter in a way that doesn’t obscure the overall meaning of the sentence (or gene). Substituting the “g” in “everything” with a “j,” for example, doesn’t alter the meaning. And many changes to a DNA sequence have no effect on the encoded amino acid sequence at all.

So that’s what a VUS is, a DNA sequence of a particular gene of interest that’s rather rare in a population, and that may or may not mean something. And their numbers will decline and then vanish as the databases build and their entries are annotated and validated. But until they do, I think that sharing all that we know about variants of possibly disease-causing genes, to prevent unnecessary treatments, is the only ethical path to take.

Kathy Greenlee’s Reflections on Paths to Person-Centered Planning

Challenging Us to See the Whole Person at All Stages of Life

Kathy Greenlee, VP for Aging and Health Policy

The Center for Practical Bioethics hosted the Joan Berkeley symposium on Thursday, April 6. The title for the day was “Paths to Person-Centered Planning.” In planning the event, my objective was to focus on tools and techniques grounded in a disability policy perspective that could benefit healthcare professionals and bioethicists. The day brought articulate and engaged speakers, raised new questions, introduced different language, and ultimately affirmed the strength of a multi-disciplinary approach to supporting people and their families as they face serious illness and end of life. 

Four distinct concepts emerged:
1) the perspective of the person as patient,
2) similarities and differences between shared decision-making and supported decision-making, 
3) the balance between what is “important to” a person and “important for” a person, and
4) the need to see a patient within the context of their family, however defined.

Person-Centered Communication

The panelists who opened the day demonstrated the importance of listening to people and the first speaker stole the show. 

Cathy Enfield, member of Self-Advocates Becoming Empowered (SABE), is an articulate adult woman with a developmental disability. She uses an iPad for communication assistance. She gave a first-person account of having healthcare providers look past her and talk directly to her caregiver. 

To communicate, Cathy needs support. Yet, public policies ranging from transportation to healthcare create barriers and financial disincentives that require her to be accompanied by someone to assist. Cathy’s comments were so compelling one of the medical educators in the audience intends to make them required reading for his first-year medical students. The problem of being looked past was affirmed in the afternoon when we discussed caring for someone with Alzheimer’s disease. The stigma surrounding dementia is so severe, patients who can communicate often become invisible as conversations shift to the caregiver only.

Negative Stereotypes

Each of the successive panelists raised important considerations. Mike Oxford, executive director for policy, Topeka Independent Living Resource Center, talked about living with chronic pain for more than 20 years. He worries that the focus on the opioid epidemic is making it more difficult for patients to get access to much needed medicine, understanding medicine is one of a variety of approaches for managing pain. Mike’s comments resonated with the Center’s work on chronic pain and the PAINS Project. 

Jean Hall, professor, Department of Health Policy and Management, University of Missouri-Kansas City and director, Institute for Health & Disability Policy Studies, is a person with multiple chronic conditions who received discouraging and inappropriate comments during her high-risk pregnancy when carrying triplets. As a researcher, she has documented lack of adequate prenatal care for woman with disabilities. 

Tyrone Flowers, a gun-shot survivor and Founder and president of Higher M-Pact, talked about the amplified issues of being an African-American male going through physical rehabilitation at the age of 18. During voc-rehab he was consistently funneled to vo-tech programs. Assumptions about his future reflected the circumstances of his childhood, not the talent he would display by graduating law school.

Shared vs. Supported Decision Making

What if your life decisions were called into question by people close to you? If the quality of your decision-making was challenged? If people started collecting evidence that you may be losing capacity?

These were the opening questions posed to us by Tina Campanella, CEO with Quality Trust for People with Disabilities in Washington, DC. People with disabilities and older people face these realities all the time. Human decision-making is complex and capacity to make decisions fluxuates. As we support other people, we need to think about how to make the most of someone’s abilities. We need to presume capacity and build from there. If we don’t presume capacity, we won’t go looking for it.

The fundamental element of supported decision-making is autonomy and control. Placing a person in the driver’s seat of their life. Dignity is the reason you presume capacity because it is important to recognize every human being has value and worth. Tina’s remarks about shared decision-making versus supported decision-making prompted a lively exchange with the audience. 

Shared decision-making comes from the healthcare field. However, sharing, by definition, means there are two loci of power: the patient and the provider. Supported decision-making presumes the person is in charge of their life. Professionals provide expertise and recommendations, but the ultimate decision-maker is the patient. The issue left unresolved is the impact on the moral agency of the healthcare provider in a supported decision-making scenario. What is the impact on the healthcare provider’s duty of care? Of the many concepts discussed, these differences in approach to decision-making are likely to generate the most additional thought and conversation. 

Patient Centered Care vs. Person-Centered Planning

The concepts of patient-centered care and person-centered planning are compatible but not interchangeable. 

Each of us are patients for only part of our lives. Robert Sattler, partner with Support Development Associates showed us a variety of documents that reflect a person-centered plan. Imagine taking a sheet of paper and some colored markers. Draw a big cartoon balloon and in it describe what you like and who is important to you. Then in another balloon, list things you don’t like. And for the third section, describe medical information that is important for others to know. In this simple manner, it is possible to capture the essence of someone in a way that is much different than an electronic health record. 
The core concept in person-centered thinking is to create a framework for identifying what is important to people while also identifying what is important for a person. For high-risk patients, professionals often focus on what is important for that person, motivated by a concern for health and safety. But a sole focus on health and safety – patient-centered care – overlooks what is unique about a person and what makes them happy. Person-centered planning challenges us to find the right balance; for someone to be both happy/satisfied and healthy/safe. A person will not do what important for them unless there is a connection to what is important to them. 

Family Relationships

All of us are part of a family, however defined, and a community. Our relationships to other people and our environment are ours to steer and something we take for granted. Michelle Reynolds (Sheli), director of the Individual Advocacy and Family Support for the Institute for Human Development at the University of Missouri-Kansas City, discussed the importance of family in relationship to a person with a disability of any age. 

Often a person with a disability needs supports with basic activities, from personal care to social engagement. However, those supports can also surround a person in such a way that they impede relationships with family, friends and community. The supports can end up defining someone’s life. After working with hundreds of people with disabilities and their families, Sheli developed a Charting the LifeCourse tool to help people plot a full and meaningful life.

The tool captures aspects of life most of us never focus on, yet each of these life domains add unique value and opportunity to the experience of life. The six domains are:
1) daily life and employment
2) community living
3) safety and security
4) healthy living
5) social and spirituality
6) citizenship and advocacy

Charting the LifeCourse reflects a core belief that all people and their families have the right to live, love, work, play and pursue their life aspirations in their community. We have a tendency to segment people based on a label. To change policy and practices, we need to think and talk about all people. All people need the six domains of daily life. For persons with disabilities, the strategy for incorporating those domains may be unique. But, then again, that is true for each of us.

The Bioethics Connection

How do these concepts fit into bioethics? Our very own Richard Payne, John B. Francis Chair at the Center for Practical Bioethics and the Esther Colliflower Professor of Medicine and Divinity at Duke Divinity School, Duke University, spoke and recalled the panel of consumers who began the day. How do we really see people? 

As a medical educator, he asks students if they can really see the person in front of them. He uses pedagogical exercises to teach this lesson. 

Don Reynolds, assistant research professor and director of the Office for Responsible Research at the University of Missouri Center for Health Ethics, as well as a Center for Practical Bioethics Fellow, provided continuity to the past and future. He has worked with the UMKC Institute for Human Development and the Center to bring attention to the need for advanced illness care planning for people with developmental disabilities. He has personally seen the continued evolution of patient centered care and believes we are on the right track to make person-centered planning work.

As we engaged in audience discussion at the end of the day, it was clear we had been challenged to see the whole life of a person in relationship to their healthcare at all stages of life. We reconnected with colleagues and met new people. We concluded the day by talking with Lex Frieden, professor of biomedical informatics, professor of rehabilitation at the University of Texas Health Science Center, and one of the pioneers responsible for the Americans with Disabilities Act.

In the end, we all experience the challenges and opportunities of life. Adding new voices and concepts to healthcare and bioethics conversations will enrich us all.

A Bioethics View of Executions in Arkansas

by Craig Klugman, Ph.D.

This week the state of Arkansas had planned to execute 8 death-row inmates in 4, back-to-back killings using lethal injection over 10 days. The last execution in Arkansas was 12 years ago, so why the sudden rush? As part of the three-drug cocktail used by this state, their supply of midazolam—an anesthetic—is about to expire. If they do not use the drug by the expiration date, then they can’t use it and the company that makes the drug will not sell it to the state for this purpose.

Arkansas had planned to use a combination of 3 drugs in the execution, midazolam (an anesthetic), vecuronium bromide (a paralytic), potassium chloride (to stop the heart).…
