Patients Should Be Told of Unexpected Gene Test Results

Patients who undergo broad DNA testing to explain a specific medical condition also should be told about chance findings that indicate risk for other serious diseases, a group of genetic specialists said.

Laboratories that conduct complete gene sequencing on patients should analyze and report on about 60 genes with known links to potentially grave conditions, such as hereditary cancers and heart conditions that can be prevented and treated, according to a report released today by a working group of the American College of Medical Genetics.

As the price of DNA analysis drops, doctors more often turn to analyzing the genome, an individuals complete genetic code, for mutations that might explain a patients illness. These wider searches increase the likelihood of discovering unexpected disease-linked genes, often called incidental findings, said Robert Green, a Harvard Medical School geneticist and chairman of the panel.

The disruptive technology of sequencing is calling for us to respond, said Green, who is also a researcher at Brigham and Womens Hospital in Boston. These are all gene variants that could make an enormous difference in a patients future medical health.

The guidelines apply to children and adults, the report said.

Faster, cheaper DNA analyzers made by Life Technologies Corp. (LIFE) and Illumina Inc. (ILMN) have dropped the price of sequencing a single human genome to about $4,000 from more than $2 billion in 2001. Government projects in the U.S., U.K., and the Faroe Islands in the North Atlantic are planning to sequence the genomes of millions of people for research and treatment.

Mutations listed in the guidelines include those that raise the risk of breast and colon cancer, heart conditions such as hypertrophic cardiomyopathy and blood disorders such as familial hypercholesterolemia. These mutations should be reported to doctors, who can decide when and how to discuss the information with patients and families, the panel said.

In most of these cases, if these mutations appear in a patients report, its going to be pretty difficult for the doctor to avoid discussing it, Green said.

Many of the diseases on the list, such as inherited cancers, are likely to arise later in life. The guidelines recommend that when mutations tied to those diseases occur in children, they should be put in the patients file and shared with parents, just like any other sign of disease risk.

An incidental finding relevant to adult disease that is discovered and reported through clinical sequencing of a child may be the only way in which that variant will come to light for the parent, the panels report said.

Gene Mutations Appear Key to Childhood Leukemia Risk, Study Says

TUESDAY, March 19 (HealthDay News) -- Children who inherit certain variations in four particular genes have an increased risk of developing childhood leukemia, a new study says.

The researchers also found that Hispanic children are more likely than white or black children to inherit high-risk versions of two of the genes that can lead to acute lymphoblastic leukemia (ALL).

Rates of ALL are higher in Hispanic children than in white or black children, and these findings point to at least one reason for that difference, according to the St. Jude Children's Research Hospital-led study.

Children inherit two copies of each gene, one from each parent. That means that children could inherit up to eight high-risk versions of the four genes linked to an increased risk of ALL, the researchers said.

Children with more than five copies of the risk genes were nine times more likely to develop ALL than those with no more than one copy, according to the study published online March 19 in the Journal of the National Cancer Institute.

The study included nearly 2,500 children with ALL and nearly 11,000 without the disease.

"ALL is a complex disease that likely involves many genes. The discoveries we are reporting in this paper are an important step forward in terms of understanding why children develop ALL in the first place, particularly for those with African or Hispanic ethnicity. However, this is probably still just a small part of the complete picture," study senior author Jun Yang, an assistant member of the St. Jude Department of Pharmaceutical Sciences in Memphis, Tenn., said in a hospital news release.

This year, about 3,000 children in the United States will be diagnosed with ALL, which is the most common childhood cancer. It is also among the most curable.

Chinese Scientists May Soon Be Able To Genetically Engineer Smarter Children

According to Vice, the scientists and researchers at BGI Shenzhen have taken on the genetic engineering project and are getting close to figuring out the common allele among the "genius" DNA.

Geoffrey Miller, an evolutionary psychologist, is among the 2,000 luminaries who donated DNA to the science of smart.

In an interview with Vice, Miller explains in more detail what exactly the research may be able to achieve, and why China is far more advanced in genetic research.

Miller says that even if IQ is boosted in one generation by a seemingly small increment, the potential of even more intelligent offspring increases as well and can improve society in all sectors. Even if it only boosts the average kid by five IQ points, thats a huge difference in terms of economic productivity, the competitiveness of the country, how many patents they get, how their businesses are run and how innovative their economy is, he said.

Chinas past with eugenics has paved a way for current Chinese geneticists and researchers to be leaders in the field, despite what many perceive as controversial science. Under the leadership of Deng Xiaoping in the late 1970s and '80s, managing Chinas booming population became a priority. By the time technology allowed for it, prenatal testing and screening for birth defects and gender were common among Chinese parents who only had one chance to have a child because of the one child policy implemented by Deng. And though gender-selecting abortion is illegal in China, this did not stop many parents from killing or abandoning baby girls.

This project, by BGI Shenzhen, Miller said, is rooted in the idea of prenatal screening, but does not cross lines of genetic engineering or adding new genes. Its the genes that couples already have, Miller said, adding that that kid would belong to that couple as if they had it naturally, but it would be the smartest a couple would be able to produce if they had 100 kids.

Miller says genetics research is so advanced in China is because of a lack of religious culture that inhibits Western research. We have ideological biases that say, well, this could be troubling, we shouldnt be meddling with nature, we shouldnt be meddling with God.

But most Chinese, Miller believes, have no qualms about genetically engineering babies.

An audience would say, Obviously you should make babies genetically healthier, happier and brighter!

Do disruptions in brain communication have a role in autism?

Public release date: 21-Mar-2013 [ | E-mail | Share ]

Contact: Vicki Cohn vcohn@liebertpub.com 914-740-2100 x2156 Mary Ann Liebert, Inc./Genetic Engineering News

New Rochelle, NY, March 21, 2013A new study of patterns of brain communication in toddlers with autism shows evidence of aberrant neural communication even at this relatively early stage of brain development. The results are presented in an article in Brain Connectivity, a bimonthly peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Brain Connectivity website at http://www.liebertpub.com/brain.

A team of researchers from The Netherlands (University Medical Center Utrecht and Utrecht University, Radboud University Nijmegen Medical Center, and VU University Medical Center, Amsterdam) compared electroencephalography (EEG) recordings from young children with and without autism. The researchers evaluated the patterns of communication between various functional neural networks in the brain that aid in the processing and integration of information.

In the article "Disrupted Functional Brain Networks in Autistic Toddlers," Maria Boersma et al. describe significant differences in the communication patterns, in particular in variables such as path length and clustering.

"This work provides support to the hypothesis that autism is a disorder of connectivity," says Christopher Pawela, PhD, Co-Editor-in-Chief and Assistant Professor, Medical College of Wisconsin. "The researchers demonstrated that autistic children's brains have both reduced brain connectivity and a diminished capacity for neural communication. This is an interesting finding and has impact on the understanding of the abnormal brain development in autistic children."

The Super Protein That Can Cut DNA and Revolutionize Genetic Engineering

When scientists Phillipe Horvath and Rodolphe Barrangou set out to find a better way to make yogurt, they didn't expect to stumble across one of the future's most promising discoveries: a super protein that can accurately cut DNAand could perhaps revolutionize genetic engineering.

The protein, called Cas9, can be exploited to snip strands of DNA in exactly the place researchers want. It doesn't make genetic engineering easy, but does make it much, much easieras it allows researchers to splice sequences of DNA together affordably, with unprecedented accuracy.

So how does it work? Well, Cas9 was found last year to join forces with bacteria in such a way that, combined, they home into viruses and kill them by cutting their DNA at specific, targeted points. That's interestingin fact, it made it a prime candidate for making yogurt production more efficient.

But what's more interesting is that Cas9 can be paired with any string of RNAstrings of molecules not unlike DNA which code and regulate gene expressionto target a matching piece of DNA and snip it with incredible accuracy. Kind of like a pair of tiny, custom DNA scissors. That's not interestingthat's amazing.

Now, though, reports Forbes, the world of biology is swarming over Cas9 and the possibilities it affords. George Church of Harvard University explains:

"It is spreading like wildfire from everyone who knows about it and it certainly is very tantalizing. It's easy to get in and start doing lots of experiments."

The embrace of Cas9 could bring with it massive advances, then. Not least the ability to study genetics in ways never before possible. Forbes explains:

[S]ay there are three changes in the DNA in or around a gene that might cause a disease. Right now, it's hard to study them directly. But now, Church says, you could take a cell from a person who has already had their DNA sequenced, as he is doing with his Personal Genome Project. Then you'd create what's known as an induced pluripotent stem cell, a cell that behaves much like one in an embryo. After that, you could use Cas9 to change each of those DNA spelling changes.

There is, of course, still a long way to gothis research is being conducted in Petri dishes right now, not living creaturesbut it's a long time since a single protein had the entire world of biology so excited. It's only a matter of time before something major comes of it; not bad, for a protein which was originally discovered to make better yogurt. [Forbes, Science]

Research Shows Genetic Evidence that New Therapies Targeting Parkinson’s Disease may Cause Harm

Released: 3/14/2013 4:00 PM EDT Embargo expired: 3/20/2013 5:00 PM EDT Source Newsroom: Mayo Clinic

Study to be presented at the annual meeting of the American Academy of Neurology by NorthShore University HealthSystem and Mayo Clinic

Newswise SAN DIEGO -- NorthShore University HealthSystem (NorthShore) and Mayo Clinic researchers have partnered on a study that shows genetic and clinical evidence that therapies targeting the expression of alpha-synuclein -- a gene whose function is involved in the development and progression of Parkinsons disease -- may accelerate disease progression and increase the risk of physical incapacitation and dementia. If replicated, the findings will have profound implications for therapies under development for Parkinsons disease.

Our research suggests therapies that seek to suppress alpha-synuclein in Parkinsons disease may actually accelerate the disease process and increase the risk for developing severe physical disability and dementia, says lead author Demetrius Maraganore, M.D., Ruth Cain Ruggles Chairman, Department of Neurology at NorthShore. We believe it is our responsibility to release these data because this type of treatment may have long-term harmful effects.

Alpha-synuclein is a major component of Lewy bodies -- a characteristic brain cell abnormality that occurs in all cases of Parkinsons disease. Since its discovery as a cause of familial Parkinsons disease nearly 20 years ago, alpha-synuclein has been the focus of intensive efforts by researchers working to definitively characterize the proteins role in idiopathic Parkinsons disease and its potential as a target for neuroprotective therapies. It has also been the focus of multiple efforts to develop a molecule that suppresses the protein function. A vaccine that targets alpha-synuclein (reducing alpha-synuclein levels) is currently in Phase I clinical trials, and a number of molecules that target the protein for reduction are in advanced stages of preclinical development.

For the first time we observed that while over-expression of alpha-synuclein increases the risk for developing Parkinsons disease, conversely, under-expression is associated with worse motor and cognitive outcomes after the disease starts, says first author Katerina Markopoulou, M.D., Ph.D., a neurologist at NorthShore. This raises concerns about the efficacy and safety of therapies designed to reduce alpha-synuclein expression in Parkinsons disease.

The researchers followed 1,098 Mayo Clinic patients for nearly 15 years (median: eight years), and sequenced the patients DNA to determine the presence of gene variants that regulate how much alpha-synuclein protein is made. They studied the association of these gene variants with patients survival that was free of severe motor and cognitive disabilities. Patient outcomes were measured by telephone interviews.

The scientists found that patients who had the reduced expression genotype had a 23 percent greater risk of becoming wheelchair-dependent or developing dementia.

This is the first large genetic association study of alpha-synuclein and longitudinal outcomes in Parkinsons disease, says Eric Ahlskog, M.D., Ph.D., a Mayo Clinic neurologist and author on the study. If replicated, this research may change the treatment paradigm focused on alpha-synuclein reduction for Parkinsons disease.

The study will be discussed at 5 p.m. EST, March 20 at the 2013 American Academy of Neurology (AAN) Annual Meeting in San Diego. This research is one example of the collaborative efforts between NorthShore and Mayo Clinic under the Mayo Clinic Care Network, a unique partnership that provides NorthShore patients with access to medical resources and experts from both systems working together on their behalf.

Arctic Genetic Pollution Effects

The cold frozen north and south are pristine and innocent. Even the people who live there. People living in Arctic areas can be more sensitive to pollutants due to their genetics, says researcher Arja Rautio at the Center for Arctic Medicine in the University of Oulu, Finland. This is unfortunate since the northernmost areas of Europe are receiving more harmful chemicals. Scientists believe climate change may be a culprit as air and water mass movements push some of these undesirable chemicals towards the Arctic. "In real life, people are exposed to lots of chemicals," says Rautio, who leads studies into the human health effects from contaminants and the influence of climate change in a EU-funded project called ArcRisk, "and I think the people of the north are exposed to higher levels than for example the general population in Europe."

The Arctic is a polar region located at the northernmost part of the Earth. The Arctic consists of the Arctic Ocean and parts of Canada, Russia, Denmark (Greenland), Norway, the United States (Alaska), Sweden, Finland, and Iceland. The Arctic region consists of a vast, ice-covered ocean, surrounded by treeless permafrost.

Long-range transport of contaminants to the Arctic, the resulting exposures observed in Arctic human populations, and impacts of such exposures on human health have been the subject of considerable work in recent years, providing a baseline against which to compare future developments.

The Arctic is comparatively clean, although there are certain ecologically difficult localized pollution problems that present a serious threat to peoples health living around these pollution sources. Due to the prevailing worldwide sea and air currents, the Arctic area is the fallout region for long-range transport pollutants, and in some places the concentrations exceed the levels of densely populated urban areas. An example of this is the phenomenon of Arctic haze, which is commonly blamed on long-range pollutants. Another example is with the bioaccumulation of PCB's (polychlorinated biphenyls) in Arctic wildlife and people.

Many new contaminants like fluorinated and brominated compounds and bisphenol A can act on hormones and so have impacts on human health. But seeing an effect on humans, at the population level, could take ten or even 20 years, especially in the case of cancer, she adds. This is why ArcRisk has established a database containing data on concentration levels and trends of contaminants in humans. The project team analysed frozen blood samples collected in Norway in 1978, 1986, 1995 and 2008 for polychlorinated biphenyls (PCBs), chlorinated pesticides and polybrominated diphenylethers (PBDEs).

In addition, the human population is genetically variable and may react differently to the chemicals and we dont even know which of the chemicals affect us.

"Moreover, some of these chemicals reside in the environment and in the body for a long time, and this means that they may build up," says Zoeller. His recently edited a recent World Health Organization report which warned that chronic diseases are increasing worldwide and many are related to hormones.

Health problems induced by these chemicals could be worse than anticipated. Some of the pollutants found in the Arctic by the project scientists like the fluorinated compounds have higher affinities for hormone receptors than even the natural hormones.

These animal studies already show worrying trends that do not bode well for humans. "When we see these findings in Arctic animals I am very concerned about what we will find with regards to humans, though we ourselves dont do human studies," Gabrielsen says. He notes that long periods of warm air are being transported to the Arctic and that the sea currents around places like the Svalbard islands [located midway between Norway and the North Pole] now consist of warmer Atlantic water; they used to consist of polar waters. "Climate change is having an effect and it is resulting in higher levels of contaminants in the environment and [therefore] also in the animals," Gabrielsen warns.

The main challenge that project scientists struggle with is to disentangle the effects of contaminant chemicals from what we do in our everyday lives. "We know that dioxins can lead to more diabetes and high blood pressure," says Rautio, "but there are many other confounding factors. We are changing our diet and many of us are less active and those lifestyle choices can also increase the risk of diseases like diabetes." The results of the project are due to be presented at a conference of Arctic Frontiers in Troms, Norway, in January 2014.

DUBLIN, March 20, 2013 /PRNewswire/ --

Research and Markets has announced the addition of the "Personalized Medicine: Companies, Trends and World Market" report to their offering.

This broad, high-level report analyzes the expanding Personalized Medicine market. This world market includes important core medical product areas that will continue to have a powerful impact on current and future healthcare delivery. This business report examines key market segments such as targeted drugs and key personalized medicine diagnostics, including companion diagnostic IVDs, LDTs, diagnostic services and related tools or technologies.

(Logo: http://photos.prnewswire.com/prnh/20130307/600769 )

Many people already know about DNA, genes and the human genome. The science driving personalized medicine includes pharmacogenetics, pharmacoproteomics and pharmacometabalomix. Personalized medicine uses a targeted drug that depends on the patient information identified by a companion diagnostic (genetic biomarker test). The companion diagnostic identifies which patients would likely benefit from a particular therapy or those who might suffer from a bad side effect. The test information enables doctors to select the drug therapy that would benefit the patient. Drug developers in clinical trials could use a companion diagnostic to select patents that would benefit from a targeted drug.

The report discusses important technologies, including microarray, next-generation sequencing, PCR, bioinformatics, nanotechnology and other platforms. This section highlights key platforms and selected vendors. For example, the field of clinical next generation sequencing is expected to have an impact on personalized medicine.

The report covers subjects including important personalized medicine concepts. The study discusses key biomarkers, commercial diagnostics and therapeutics that drive personalized medicine. The study highlights new personalized diagnostics. This research examines the current targeted therapeutics on the market and drugs in the clinical pipeline.

The report highlights major government regulatory activities that involve personalized medicine in the US and Europe. The US FDA and the European EMA have drafted guidance papers to help drug makers and diagnostic firms develop future targeted therapies guided by companion diagnostics. The recent FDA approvals of Pfizer's Xalkori for lung cancer and Roche's Zelboraf for melanoma demonstrate that a surge in new targeted drugs is happening.

This report is in an interactive PDF format. The interactive feature uses hyperlinks that enable the reader to click the mouse to jump from Table of Contents items to sections inside the report. The hyperlinks also allow the reader to click on links to Internet information.
