Brca1 Gene Quotes

Gene patents are the point of greatest concern in the debate over ownership of human biological materials, and how that ownership might interfere with science. As of 2005—the most recent year figures were available—the U.S. government had issued patents relating to the use of about 20 percent of known human genes, including genes for Alzheimer’s, asthma, colon cancer, and, most famously, breast cancer. This means pharmaceutical companies, scientists, and universities control what research can be done on those genes, and how much resulting therapies and diagnostic tests will cost. And some enforce their patents aggressively: Myriad Genetics, which holds the patents on the BRCA1 and BRCA2 genes responsible for most cases of hereditary breast and ovarian cancer, charges $3,000 to test for the genes. Myriad has been accused of creating a monopoly, since no one else can offer the test, and researchers can’t develop cheaper tests or new therapies without getting permission from Myriad and paying steep licensing fees. Scientists who’ve gone ahead with research involving the breast-cancer genes without Myriad’s permission have found themselves on the receiving end of cease-and-desist letters and threats of litigation.

Scientists who’ve gone ahead with research involving the breast-cancer genes without Myriad’s permission have found themselves on the receiving end of cease-and-desist letters and threats of litigation. In May 2009 the American Civil Liberties Union, several breast-cancer survivors, and professional groups representing more than 150,000 scientists sued Myriad Genetics over its breast-cancer gene patents. Among other things, scientists involved in the case claim that the practice of gene patenting has inhibited their research, and they aim to stop it. The presence of so many scientists in the suit, many of them from top institutions, challenges the standard argument that ruling against biological patents would interfere with scientific progress

Until recently, three unspoken principles have guided the arena of genetic diagnosis and intervention. First, diagnostic tests have largely been restricted to gene variants that are singularly powerful determinants of illness—i.e., highly penetrant mutations, where the likelihood of developing the disease is close to 100 percent (Down syndrome, cystic fibrosis, Tay-Sachs disease). Second, the diseases caused by these mutations have generally involved extraordinary suffering or fundamental incompatibilities with “normal” life. Third, justifiable interventions—the decision to abort a child with Down syndrome, say, or intervene surgically on a woman with a BRCA1 mutation—have been defined through social and medical consensus, and all interventions have been governed by complete freedom of choice. The three sides of the triangle can be envisioned as moral lines that most cultures have been unwilling to transgress. The abortion of an embryo carrying a gene with, say, only a ten percent chance of developing cancer in the future violates the injunction against intervening on low-penetrance mutations. Similarly, a state-mandated medical procedure on a genetically ill person without the subject’s consent (or parental consent in the case of a fetus) crosses the boundaries of freedom and noncoercion. Yet it can hardly escape our attention that these parameters are inherently susceptible to the logic of self-reinforcement. We determine the definition of “extraordinary suffering.” We demarcate the boundaries of “normalcy” versus “abnormalcy.” We make the medical choices to intervene. We determine the nature of “justifiable interventions.” Humans endowed with certain genomes are responsible for defining the criteria to define, intervene on, or even eliminate other humans endowed with other genomes. “Choice,” in short, seems like an illusion devised by genes to propagate the selection of similar genes.

in BRCA-1 has a 50 to 80 percent chance of developing breast cancer in her lifetime (the gene also increases the risk for ovarian cancer), about three to five times the normal risk.
