Genetic counselors turn to unconventional counseling to meet demand for genetic testingMarch 17, 2008Imagine receiving genetic test results for a disease you could develop later in life without having anyone with whom to discuss your options for managing the risk. That's becoming a common occurrence as people turn to the Internet and other outlets for genetic testing without genetic counseling. In an effort to broaden accessibility to genetic counseling, researchers are exploring non-conventional counseling methods that challenge traditional approaches. "The delivery of genetic test results for a disease like cancer can trigger a range of emotions and can be more distressful than anticipated-- particularly when there's been no counseling and the results are 'positive'," explains Beth N. Peshkin, MS, CGC, senior genetics counselor at Lombardi Comprehensive Cancer Center, part of Georgetown University Medical Center, and educational director of the Jess and Mildred Fisher Center for Familial Cancer Research. "While in-person genetic counseling is ideal, it's not convenient for people who live in rural areas or don't have access to an academic center." According to Peshkin, genetic counseling and testing, particularly for adult onset conditions, is a trend that will continue to grow as additional genes are identified and as such testing diffuses into mainstream clinical care. Telephone counseling has been utilized with increased frequency despite a lack of data about its efficacy and concern about its use as a substitute for face-to-face contact with patients. "In anticipation of this increased demand, it is imperative we find alternatives to traditional genetic susceptibility counseling and that we develop and evaluate these possible options now," Peshkin explains. "A successful alternative would be one that effectively delivers information but allows greater accessibility, such as telephone counseling." To address these issues, Peshkin and her colleagues have launched a randomized clinical trial -the largest to date- at Lombardi to evaluate telephone genetic counseling versus in person (standard) genetic counseling among women at high risk of carrying a BRCA1/2 mutation. The study is outlined in the Spring edition of the journal Genetic Counseling posted online today. "Many of us favor face-to-face counseling but the reality is the telephone may allow us to reach more people, more efficiently" says Peshkin. "It makes sense to develop interventions that parallel the traditional model while extending its reach and deliverability." Peshkin points to the abundant clinical data on the epidemiology of BRCA1/2 and the efficacy of various management strategies. Also, evidence attests to the efficacy of traditional genetic counseling at increasing knowledge, prospectively improving the accuracy of perceived risk, and increasing the awareness of the risks and benefits of testing. "Patients appear to be highly satisfied with the traditional format of comprehensive genetic counseling so a study among individuals undergoing BRCA1/2 testing is an ideal population on which to evaluate alternative models of counseling," Peshkin says.

Breast cancer patients with high risk gene diagnosed 6 years earlier than generation before Women with a deleterious gene mutation are diagnosed with breast cancer six years earlier than relatives of the previous generation who also had the disease and/or ovarian cancer, according to new research from The University of Texas M. D. Anderson Cancer Center. Discovery of genetic mutation in Leigh syndrome Researchers at the Montreal Neurological Institute and Hospital (The Neuro), McGill University have discovered a genetic mutation underlying late-onset Leigh syndrome, a rare inherited metabolic disorder characterized by the degeneration of the central nervous system. Women often opt to surgically remove their breasts, ovaries to reduce cancer risk Many women at high risk for breast or ovarian cancer are choosing to undergo surgery as a precautionary measure to decrease their cancer risk. DNA template could explain evolutionary shifts Rearrangements of all sizes in genomes, genes and exons can result from a glitch in DNA copying that occurs when the process stalls at a critical point and then shifts to a different genetic template, duplicating and even triplicating genes or just shuffling or deleting part of the code within them, said researchers from Baylor College of Medicine in a recent report in the journal Nature Genetics. Researchers estimate risk of transmission of Huntington's disease to offspring among male carriers Researchers from Boston University School of Medicine (BUSM) have quantified the probability of a male who carries a "high normal" variant of the Huntington's Disease (HD) gene having a child who develops the disease. Mothers satisfied when they share cancer genetic test results with children Mothers who share cancer genetic test results with their children are more satisfied with their decision than those who decide not to tell, according to a new study by researchers at the Lombardi Comprehensive Cancer Center at Georgetown University Medical Center. Muscular dystrophy diagnosis delayed almost 2.5 years in boys Boys show signs of Duchenne Muscular Dystrophy (DMD) for 2 ˝ years before they obtain a diagnosis and disease-specific treatment, about the same length of delay children have endured for the past 20 years despite advances in genetic testing and treatment. Women with BRCA mutation, or worry, most likely to undergo prophylactic mastectomy Women at increased risk for breast cancer because of the genetic BRCA mutations are more likely to think a prophylactic mastectomy is the best way to reduce their risk for the disease, compared to other women who are at high risk, according to researchers at The University of Texas M. D. Anderson Cancer Center. No differences in survival or neonatal outcomes in pregnancy-associated colorectal cancer In one of the first studies to examine maternal and newborn health risks and colorectal cancer, UC Davis researchers have found that women diagnosed with the disease during or shortly after their pregnancies have the same survival as women who have the disease and are not pregnant.
