Advances in Genetic Sequencing to Augment Growth in the Predictive Diagnostics Market, According to New Report by …

San Jose, California (PRWEB) October 04, 2013

Follow us on LinkedIn Predictive diagnostics refer to a series of genetic tests that determine individual susceptibility to diseases, individual response to specific therapies/interventions and the outcome of diseases. Genetic testing has emerged as a lucrative sector in the molecular diagnostics market led by the fact that appropriate and accurate diagnosis is the cornerstone of advanced healthcare. Predictive testing involves identifying the presence or inheritance of faulty gene among members of a family, such as those resulting in Tay-Sachs disease, cystic fibrosis, Lou Gehrig's disease, Huntington's disease and Alzheimer's disease. Predictive diagnostics are also beneficial in examining the gene composition and interaction in diseased tissue/cells to understand and determine progress of the disease as well as the response to treatment.

Though a relatively small market, predictive diagnostics is witnessing steady growth owing to increasing awareness among medical professionals and patients. Proportional to rising life expectancy and mean age, chronic degenerative diseases (CDD) including cardiovascular diseases, neurodegenerative disorders, cancer and autoimmune diseases, have surged globally, translating into demand for predictive testing. The rapidly ageing society in major Western and Eastern economies is therefore a prime driver of demand for predictive diagnostics for age-related disorders. Traditionally offered through physicians, genetic testing kits are now being offered directly to the consumer through web-based stores. However, the security and utility of DTC genetic testing kits is being questioned as several companies tend to circumvent third party reimbursement and regulatory issues.

Decreasing costs coupled with the enhanced efficiency and speed of gene sequencing has resulted in rapidly unfurling information on cancer gene mechanisms. With the cost of sequencing the entire genome falling below US$1,000 in comparison to anti-cancer treatments which cost over US$50,000, physicians are opting to conduct genomic tests to determine patient drug response, following which medications are prescribed to only those patients who are more likely to respond to a specific cancer therapy or treatment option. Technological advancements in genomics such as Next-Generation Sequencing (NGS) are replacing conventional DNA sequencing modalities. Advanced NGS systems offer the capability of sequencing and comparing up to 4 human genomes within a space of two weeks. Demand for genetic tests designed for screening newborn infants, diagnosis of orphan diseases and other rare or fatal disorders, and assessment of the probability of occurrence of conditions such as Huntingtons disease, is expected to expand dramatically in the near term. On the flip side, as the new era of genetic medicine dawns upon the healthcare sector, the need of the hour is a clear and comprehensive framework addressing the medical, economic, ethical and legal aspects of subjecting healthy individuals to genetic testing for disease prevention.

As stated by the new market research report on Predictive Diagnostics, the United States represents the largest market worldwide. Screening for genetic mutations within the CFTR (cystic fibrosis trans-membrane conductance regulator) gene is the most frequently conducted test in the country. While developed economies with advanced healthcare infrastructure are at the forefront in the adoption of predictive genetic testing, population growth and recent government initiatives to improve healthcare delivery to all sections of the population is expected to propel demand in developing countries in the near future. Countries such as China harbor the largest prospects for breast cancer gene testing. Attributed to lifestyle changes as a result of rapid industrialization and increasing urbanization, the country is registering a surge in cases of breast cancer.

Major players covered in the report include Abbott Molecular, Almac Group Ltd., BioGenex, Covance Inc., Dako Denmark A/S, Epistem Plc, F. Hoffmann-La Roche Ltd., Genomic Health, Inc., MDxHEALTH Inc., Myriad Genetics Inc., Precision Therapeutics Inc., Prometheus Laboratories, QIAGEN N.V., among others.

Critics fear new patent will breed "designer babies"

Controversy is brewing after a genetics company received a patent that might allow prospective parents to calculate the traits of their future offspring.

23AndMe is a company that allows the average consumer to analyze their genetic code. The test provides genetic information on more than 240 disease and physical traits, which can be used for various reasons including determining personal risk of getting breast cancer or helping long-lost siblings find each other.

Play Video

"We started the company really with the idea that we wanted to do something revolutionary, where consumers could come, learn tons of information about themselves and really start to revolutionize health care," 23andMe co-founder Anne Wojcicki previously told CBS This Morning in July 2012.

The U.S. company recently received a patent for their Family Traits Inheritor Calculator, which allows couples to send in a saliva sample to see what kinds of genetic traits and diseases could be passed to their children.

However, the application for the patent stated that the company was also seeking to use this technology in fertility clinics. This led critics to think that couples could potentially create "designer babies," not only picking children based on disease avoidance but on their looks and other physical characteristics. Especially in the fertility clinic setting, the "GATTICA"-like scenario would allow couples to screen through numerous egg and sperm donors in order to pick a genetically superior child.

"It would be highly irresponsible for 23andMe or anyone else to offer a product or service based on this patent," Marcy Darnovsky, executive director of the Center for Genetics and Society, said in a statement.

"We believe the patent office made a serious mistake in allowing a patent that includes drop-down menus for which to choose a future child's traits," she added.

A commentary in Genetics and Medicine published on Oct. 3 also warned against parents using the technology to hand-pick genes for their children. The authors called the practice "ethically controversial."

"The use of preimplantation genetic diagnosis to avoid implantation of embryos bearing serious genetic abnormalities is by now becoming commonplace, but a computerized process for selecting gamete donors to achieve a baby with a 'phenotype of interest' that the prospective parent 'desires in his/her hypothetical offspring,' as 23andMe puts it, seems to have much broader implications, for this process also entails the selection of traits that are not disease related," they wrote.

Gene scans help solve mystery diseases in kids, adults

They were mystery diseases that had stumped doctors for years - adults with strange symptoms and children with neurological problems, mental slowness or muscles too weak to let them stand. Now scientists say they were able to crack a quarter of these cases by decoding the patients' genes.

Their study is the first large-scale effort to move gene sequencing out of the lab and into ordinary medical care, and it shows that high hopes for this technology are finally paying off.

"This is a direct benefit of the Human Genome Project," the big effort to decode our DNA, said Dr. Christine M. Eng of Baylor College of Medicine in Houston. "We're now able to directly benefit patients through more accurate diagnosis."

She led the study, which was published online Wednesday by the New England Journal of Medicine. It gives results on the first 250 patients referred to Baylor for a newer type of sequencing - just the DNA segments that hold the recipes for all the proteins the body needs. That's only about 1 percent of the whole genome.

Baylor has sequenced more patients beyond those in the study - 1,700 so far - and found gene flaws in 1 out of 4, Eng said.

That rate will improve as more genes are linked to diseases, but it's already much higher than the less comprehensive gene tests done now, said Rebecca Nagy, a scientist at Ohio State University and president of the National Society of Genetic Counselors.

"For some of these conditions there could be treatments that are lifesaving," she said.

Already, three people tested at Baylor were found to have a muscle disorder that can cause respiratory problems and even death. The condition is aggravated by infections and stress, and there are drugs to treat those and prevent serious episodes, Eng said.

In other cases, having a diagnosis helped parents like Lindsey and Brandon Collier decide whether to have more children. The Colliers, who live in Georgetown, Texas, about 30 miles north of Austin, searched for years for an answer to what was plaguing their son, Cannon, now 4.

"He was a pretty floppy baby" with poor muscle tone and problems eating, Lindsey Collier said. "We weren't getting any answers and they were just all over the map on everything they were testing for."

Rett syndrome gene dysfunction redefined

Public release date: 3-Oct-2013 [ | E-mail | Share ]

Contact: Nicole Rura rura@wi.mit.edu 617-258-6851 Whitehead Institute for Biomedical Research

CAMBRIDGE, Mass. (October 3, 2013) Whitehead Institute researchers have redefined the function of a gene whose mutation causes Rett syndrome, a neurodevelopmental autism spectrum disorder. This new research offers an improved understanding of the defects found in the neurons of Rett syndrome patients and could lead to novel therapies for the disease.

"The action of the MECP2 protein is just the opposite of how it was held for the past 15 years," says Whitehead Founding Member Rudolf Jaenisch, who is also a professor of biology at MIT. "It was thought that this protein globally repressed the expression of methylated DNA. What this work shows is when you do the analysis in a way that takes cell size into accountcell size is very different in Rett neurons compared to wild typethen suddenly we can see that the protein acts like a global activator. We've defined the function of MECP2 in a totally different way."

Rett syndrome is an X-linked genetic disease affecting one in 10,000 newborn girls. Infants with the disease appear to develop normally for their first six to 18 months, at which point their movement and language skills begin to deteriorate. Loss of speech, reduced head size, breathing and heart rhythm irregularities, and autistic-like symptoms are common by age four. Some symptoms may be treated with prescription drugs, but no cure or disease-modifying therapy exists. Previous work by the Jaenisch lab has provided some hope for the families of Rett patients. In a mouse model lacking the MECP2 gene, which is mutated in approximately 95% of girls with Rett syndrome, mice injected with the protein IGF-1 had more regular breathing and heart rhythms than did untreated mice. In addition, the brains of treated mice had greater mass and more of the vital neuronal projections that are missing in Rett syndrome mice and human patients.

In the current research, Yun Li, a postdoctoral researcher in the Jaenisch lab, analyzed the global gene expression of MECP2-deficient neurons derived from human embryonic stem cells. Unlike earlier research, Li took into account the Rett neurons' smaller size when comparing their gene expression to neurons with intact MECP2. The Rett neurons had decreased mRNA transcription, reduced protein synthesis, and severe defects in the AKT/mTOR signaling pathway, which is activated by IGF-1. Li's work is published in the October 2nd issue of Cell Stem Cell.

"We have always found it strange that MECP2 mutant mice, which share many of the severe neurological problems as really sick kids with Rett syndrome, have very few transcriptional changes detectable on a microarray. That doesn't seem to support a global repressor role for the MECP2 protein. There had to be something wrong," says Li. "Now we have a much better understanding of the function of MECP2, and the severity of the disease on a cellular level. Knowing that human Rett neurons are impaired in both global transcription and translation is important for us to design therapeutic strategies for Rett. Growth factors such as BDNF and IGF-1 are known to activate the AKT/mTOR pathway and increase protein synthesis. Down the road, we are interested in further exploring the Akt/mTOR pathway, and investigate how activation of this pathway could reverse the disease."

Raúl receives President of Timor-Leste

Ral receives President of Timor-Leste President visits Genetic Engineering and Biotechnology Center

PRESIDENT Ral Castro Ruz received on September 27 President Taur Matan Ruak of the Democratic Republic of Timor-Leste, during the latters official visit to Cuba.

After the official reception ceremony, the two leaders reviewed the excellent state of bilateral relations and expressed their will to consolidate cooperation, particularly in the context of health and education. They also discussed current international issues.

During his stay, the Timor Leste President and his delegation met with scientists at the Genetic Engineering and Biotechnology Center (CIGB), where they were presented with medicines developed by this institution, such as the recognized Heberprot-P for the treatment of diabetic foot ulcers, and the vaccine against Hepatitis B, included on the 171 registers of 14 products in 57 countries, as the CIGB researchers confirmed.

Timorese Health Minister Sergio Gama Lobo showed interest in these two Cuban products and inquired into their application.

The scientists also referred to the possibility of establishing cooperation between the institution and the Timor Leste government for the treatment of foot ulcers, as a way of raising the quality of life of persons suffering from diabetes.

At the end of his visit to the Center, President Taur Matan Ruak affirmed that there are two ways of treating people in the world: one is preventative and the other curative, and the better one is that of Cuba; preventative health care.

He subsequently stated that education and innovation are key to increased collaboration between the two nations, which he reiterated before leaving the country, saying that he is seeking to consolidate relations between Timor Leste and Cuba, above all in the health and education sectors.

Genetically Modified Bacteria Produce 50 Percent More Fuel

By changing the way certain organisms process sugar, UCLA researchers have shown how to produce more biofuel.

Ethanol boosters: The bacteria in this petri dish have been genetically modified to increase the amount of biofuel that can be made from sugar.

Researchers at UCLA have opened a path to cheaper and cleaner biofuels by using genetic engineering to fundamentally change how certain organisms process sugar.

Conventional biofuels are either too expensive to compete with fossil fuels or they release so much carbon dioxide that theyre hardly worth makingor both.

The UCLA advance, which increases the amount of biofuel that can be made from sugar by 50 percent, could make it cheaper to produce biofuels from a variety of sources, especially biomass such as wood chips and grass. The U.S. biofuels industry is in desperate need of such advanceseven though Congress has mandated that a certain amount of biofuel from biomass be blended with gasoline, high costs and other factors have limited production, leading the EPA to repeatedly waive the requirement.

The UCLA work is a promising advance in biofuels technology, says Wade Robey, chief technology officer at the ethanol producer POET. He says it shows the potential of advanced genetic engineering to drastically reduce both greenhouse gas emissions and the amount of corn or biomass used to produce a gallon of biofuel.

In conventional biofuels production, sugar derived from sources such as corn and biomass is fed to yeast, which ferments it to produce ethanol. But the fermentation process wastes a third of the carbon atoms that make up sugar; rather than being used to make ethanol, the carbon is released in the form of carbon dioxide.

The UCLA researchers cobbled together genes from a variety of organisms to create an alternate way to process sugar that doesnt emit any carbon dioxide, and uses all of the carbon in sugar to make biofuel. They created genetically modified E. coli bacteria to demonstrate the process, but they say the same genetic pathway could be incorporated into other organisms, including yeast.

Anytime you use fermentation, you lose one-third of the carbon to carbon dioxide. We can retain that carbon, reduce the carbon footprint of ethanol production, and make more money, says James Liao, professor of chemical and biomolecular engineering at UCLA.

In order to use all of the carbon in sugar, its necessary to add hydrogen to the process. The source of that hydrogen and its cost relative to the cost of sugar determine both the total carbon emissions and the cost savings. Using hydrogen from natural gas is the cheapest option. But getting hydrogen from natural gas also releases carbon dioxide, offsetting some of the carbon dioxide savings of the new process. In this case, emissions from the production of ethanol would be reduced by about 50 percent. Using hydrogen made by splitting water with solar power would eliminate all of the carbon dioxide emitted during fermentation, but the cost would likely be too high for the process to be economical.

New MRI technique detects genetic condition that attacks the heart, brain, nerves

Oct. 2, 2013 A genetic condition that attacks multiple organs and usually results in fatal heart problems can be detected using a new MRI technique that was developed at the University of Alberta. The discovery of this new diagnostic tool has resulted in updated clinical guidelines for the diagnosis and treatment of Fabry disease in Canada.

Faculty of Medicine & Dentistry researchers Gavin Oudit and Richard Thompson worked with Faculty colleagues Kelvin Chow and Alicia Chan on the discovery, as well as Aneal Khan from the University of Calgary. The findings were recently published in the peer-reviewed journal, Circulation -- Cardiovascular Imaging, and involved 31 Alberta patients who have the disease.

Thompson and trainee Chow developed the MRI technique known as T1 mapping which can detect heart damage and changes at early stages -- earlier than regular MRI scans or ultrasound. When this type of MRI is used on patients with Fabry disease, the scans can detect both the disease and the severity of damage to the heart. The T1 mapping method developed by Thompson's group can be easily programmed onto MRIs around the world.

"This test can uniquely identify Fabry disease by detecting microscopic changes in the heart muscle structure that are not visible on regular images," says Thompson, who works in the Department of Biomedical Engineering. "Fabry disease can look like other diseases if you only look at the whole heart structure or function, but this T1 mapping test, that can detect the tiniest changes in the heart, could identify all the patients with Fabry disease."

Oudit added: "It is very likely that this technique will become a key part in clinical examination of patients with Fabry disease. This finding will advance the clinical care of these patients around the world. The implications will be widespread.

"Heart disease is the number one cause of death for patients with Fabry disease. The earlier the disease can be pinpointed, the sooner treatment can start. The treatment for the disease halts the condition and prevents serious damage to the heart."

Fabry disease is a genetic metabolic condition that destroys the enzyme involved in fat metabolism. This enzyme breaks down fat so without it, those with the disease accumulate deadly fat deposits in their heart, kidneys and brain. The condition affects 1 in 1,500 to 3,000 people, but was originally thought to be a rare disease. Some countries now screen newborns for the condition that costs $200,000 a year to treat through monthly infusions called enzyme replacement therapy. Symptoms of the disease include: heart failure, thickened walls of the heart, exercise intolerance, fluid buildup in the legs, blackouts, inability to lie down, strokes, tingling in the hands and feet, and changes in skin pigmentation.

It is estimated that about 1,000 Albertans are living with the disease but not everyone who has the condition has been diagnosed. Sometimes people will see scores of kidney and heart specialists for years before anyone diagnoses the condition. Men can have a blood test to identify the condition, while women -- who may also carry the disease without showing symptoms -- need to undergo genetic testing. The T1 mapping test can both pinpoint the disease and assess damage to the heart.

Oudit says the discovery of the new MRI technique "is a wonderful story of collaboration -- of patients, clinicians, scientists and industry working together to find a new diagnostic tool." Oudit is a heart failure specialist who works in the Division of Cardiology in the Department of Medicine at the Mazankowski Alberta Heart Institute.

"As an organization, we are excited to be part of these developments through the research from the University of Alberta," says Mauro Chies, acting vice-president of clinical supports for Alberta Health Services. "This is a significant advancement in the detection of disease in a non-invasive environment for our patients. We hope to be able to advance these sequences on our MRIs in the near future, and look for ways to use it to evaluate and detect other disease conditions."

Genetic analysis of individuals with autism finds gene deletions

NEW YORK (October 3, 2013) -- Using powerful genetic sequencing technology, a team of investigators, led by researchers at the Icahn School of Medicine at Mount Sinai, scanned the genome of hundreds of individuals, and discovered those diagnosed with autism spectrum disorder (ASD) were more likely to have gene deletions than were people without the disorder. That means those individuals -- seven percent of the study group -- had one copy of one or more genes when they should have had two.

The scientists further report, in the American Journal of Human Genetics, that their analysis suggests the deletions may result in the miswiring and altered activity of brain neurons.

"This is the first finding that small deletions impacting one or two genes appear to be common in autism, and that these deletions contribute to risk of development of the disorder," says the study's lead investigator, Joseph D. Buxbaum, PhD, Professor of Psychiatry, Genetics and Genomic Sciences and Neuroscience at the Icahn School of Medicine at Mount Sinai.

"This conclusion needs to be expanded in other independent samples of ASD so that we can truly understand how the risk manifests," he says.

That process is now ongoing, Dr. Buxbaum adds. The Autism Sequencing Consortium, a group of over 25 institutions, was awarded a $7 million grant from the National Institutes of Health to continue analyzing the genomes of thousands of ASD individuals at Mount Sinai.

First look for missing genes in autistic population

Autism, which affects about one percent of the population, is a developmental disorder thought to be caused by a complex interplay between genetic and environmental factors. Although the disorder is highly heritable, the majority of autism cases cannot be attributed to known inherited causes, Dr. Buxbaum says.

While research has indicated that there might be as many as 1,000 genes or genomic regions that contribute to ASD, most studies have looked for either single point mutations -- a change in a single letter of DNA on a gene -- or for large areas of the genome, encompassing many genes, that is altered.
