Cystic fibrosis testing -- next steps
April 28, 2009San Juan Capistrano, CA and Chantilly, VA -Three reports describing advances in cystic fibrosis genetic testing appear in the May 2009 issue of The Journal of Molecular Diagnostics.
Cystic fibrosis is a hereditary disease that affects mucus secretions in the lungs, liver, pancreas, and intestines. Approximately 1 in 4000 children born in the United States is affected with cystic fibrosis. Cystic fibrosis is an autosomal recessive disease caused by mutations in the CFTR gene; cystic fibrosis patients must inherit a mutated gene from each parent.
Genetic screening for cystic fibrosis carrier mutations (one copy of a mutated gene) is universally recommended for the reproductive-age population. Current professional guidelines call for screening a panel of 23 common mutations in CFTR; however, many laboratories screen for an expanded panel of mutations. In the May 2009 issue of The Journal of Molecular Diagnostics, three articles describe improvements in cystic fibrosis genetic screening. In one article, Pratt et al describes a project coordinated by the Centers for Disease Control and Prevention's Genetic Testing Reference Material (GeT-RM) Program to develop a set of reference materials for the expanded cystic fibrosis panel of mutations. The public availability of these materials will help to ensure the accuracy of cystic fibrosis genetic testing. The reports by Schwartz et al and Hantash et al identify mutations that may lead to false screening results, either due to a large deletion in CFTR or because of mutations that interfere with laboratory screening methods.
Wayne Grody, of the UCLA School of Medicine, Los Angeles, CA, who is not affiliated with these studies, states "Taken together, these three papers demonstrate how the widespread and thoughtful experience with [cystic fibrosis] mutation testing and screening continues to reveal new insights about the mutational alleles of the CFTR gene and further refinements in how best to detect them and assure appropriate quality control while doing so."

Cystic Fibrosis Current Events and Cystic Fibrosis News RSSBacteria 'launch a shield' to resist attack
Researchers from the University of Copenhagen and the Technical University of Denmark along with other collaborators in Denmark and the US found that the bacterium Pseudomonas aeruginosa can 'switch on' production of molecules that kill white blood cells - preventing the bacteria being eliminated by the body's immune system.
Protein critical for insulin secretion may be contributor to diabetes
A cellular protein from a family involved in several human diseases is crucial for the proper production and release of insulin, new research has found, suggesting that the protein might play a role in diabetes.
New clinical guidelines for exacerbations in cystic fibrosis
The American Thoracic Society has released new clinical guidelines for the treatment of exacerbations in cystic fibrosis based on a review of the literature on current clinical practices.
Nanoparticle treatment for burns curbs infection, reduces inflammation
Treating second-degree burns with a nanoemulsion lotion sharply curbs bacterial growth and reduces inflammation that otherwise can jeopardize recovery, University of Michigan scientists have shown in initial laboratory studies.
Research Matters at the Arizona Health Sciences Center (AHSC): UA Researchers Seek Safer Cystic Fibrosis Test
Researchers from The University of Arizona Colleges of Pharmacy and Medicine are teaming up to try to invent a novel non-invasive lung test for cystic fibrosis sufferers.
Species diversity helps ASU researchers refine analyses of human gene mutations
In the new era of personalized medicine, physicians hope to provide earlier diagnoses and improve therapy by evaluating patients' genetic blueprints. But, as a new bioinformatics study emphasizes, the first step must be to correctly decipher the deluge of information locked in our DNA and determine its impact on human health.
New developments in reproductive medicine
Three out of ten women who undergo polar body diagnosis go on to have a child.
Faster, cheaper way to find disease genes in human genome passes initial test
University of Washington (UW) researchers have successfully developed a novel genome-analysis strategy for more rapid, lower cost discovery of possible gene-disease links.
Mutation responsible for cystic fibrosis also involved in muscle atrophy
Patients with cystic fibrosis (CF) usually experience significant muscle loss, a symptom traditionally considered to be a secondary complication of the devastating genetic disease.
Test helps in fight against lung infections and for treating other life-threatening infections
A new test developed by Edmonton-based Innovotech™ Inc. will now allow doctors to more accurately identify the right antibiotics required to treat serious, chronic infections that are biofilm based.

Cystic Fibrosis: Everything You Need To Know (Your Personal Health) by Wayne Kepron MD FRCPC (Author) Cystic fibrosis afflicts approximately 30,000 Americans. The average age of survival has been steadily increasing, but not quickly enough: a child born with cystic fibrosis today can only expect to live 35 to 40 years. In this valuable new addition to the Your Personal Health series, Dr. Wayne Kepron offers a comprehensive look at the disease that afflicts so many young people. Topics include: - Symptoms of cystic fibrosis - Making a diagnosis - Complications of the disease - Treatments (including lung transplants) - Techniques and precautions in lung care - Transition into adulthood - Prospects for gene therapy - End-of-life issues Using diagrams, charts and case studies, Cystic Fibrosis is designed for patients, their families, and caregivers. It is both a quick... |

The Power of Two: A Twin Triumph over Cystic Fibrosis by Isabel Stenzel Byrnes; Anabel Stenzel (Author) The tragedy of cystic fibrosis has been touchingly recounted before, but this is the first book to portray the symbiotic relationship between twins who share this life-threatening disease through adulthood. Isabel Stenzel Byrnes and Anabel Stenzel tell of their struggle to pursue normal lives while grappling with the realization that they might die young. Their story reflects the physical and emotional challenges of a particularly aggressive form of CF and tells how the twins bicultural heritage Japanese and German influenced the way they coped. The Power of Two is an honest and gripping portrayal of day-to-day health care, the impact of chronic illness on marriage and family, and the importance of a support network to continuing survival. These two remarkable sisters have much to teach... |

Cystic Fibrosis (Facts) by Ann Harris (Author), Anne Thomson (Author) Cystic Fibrosis: The Facts provides a much needed simple and understandable source book about this disease. It is aimed at those living with Cystic Fibrosis (CF), either themselves or members of their families or their friends. The book explains clearly what is happening to the body in CF, what causes it and what treatment options are available for the different aspects of the disease. There are more detailed chapters for those wanting to find out about the genetics of the disease and specific aspects such as how it affects life choices and employment. It looks to the future in terms of potential new therapies for CF and provides useful information on organizations that can provide help and further information across those areas of the world where the disease is prevalent. |
