Edward I. Ginns, MD, PhD, Director Program in Medical Genetics and Lysosomal Disorders Treatment and Research Program University of Massachusetts Medical School Reed Rose Gordon Building, Room 137 Shrewsbury, MA 01545MedicalResearch.com: Interview with: Edward I. Ginns, MD, PhD, Director Program in Medical Genetics and Lysosomal Disorders Treatment and Research Program University of Massachusetts Medical School Reed Rose Gordon Building, Room 137 Shrewsbury, MA 01545 Medical Research: What are the main findings of the study? Dr. Ginns: Our study identified that sonic hedgehog signaling, an important brain pathway, is involved in bipolar affective disorder. This finding shows a mechanism and provides new targets for drug development. It suggests that sonic hedgehog signaling can be modulated to help manage bipolar symptoms in adults by using drugs already being studied in clinical trials for other medical conditions. The new findings were uncovered by decades of translational research in the Old Order Amish families of Pennsylvania, where in a few special families in the Amish Study there is a high incidence of both bipolar disorder and a rare genetic dwarfism, Ellis van‐Creveld (EvC) syndrome. No person with EvC had bipolar disorder despite forty years of documented research across multiple generations, suggesting that the genetic cause of this rare dwarfism was protective of bipolar affective disorder.

Dr. Yann C Klimentidis, PhD Assistant professor of Epidemiology and Biostatistics Mel and Enid Zuckerman College of Public Health University of Arizona Medical CenterMedicalResearch.com Interview Invitation with: Dr. Yann C Klimentidis, PhD Assistant professor of Epidemiology and Biostatistics Mel and Enid Zuckerman College of Public Health University of Arizona Medical Center   Medical Research: What are the main findings of the study? Dr. Klimentidis: The main finding is that the association of physical activity with type-2 diabetes risk is weakest among those who are at high genetic risk for type-2 diabetes. Furthermore, we find that this trend is stronger among women as compared to men, and that it appears to be driven mainly by genetic risk to insulin resistance, as opposed to genetic risk for reduced beta-cell function.

Dr. Jyotsna Batra QUT Institute of Health and Biomedical Innovation's Queensland University of Technology Queensland, AustraliaMedicalResearch.com Interview with: Dr. Jyotsna Batra QUT Institute of Health and Biomedical Innovation's Queensland University of Technology Queensland, Australia   Medical Research: What are the main findings of the study? Dr Batra: Prostate cancer is a disease with upto 40% genetic component. Previous Genome-wide association studies have identified 77 risk loci associated with prostate cancer. This study is further extension of previous GWASs and also involved meta-analysis of multi-ethnic populations. Through this large study involving approximately 90,0000 individuals, 23 new susceptibility loci were identified to be associated with prostate cancer, 15 variants were identified among men of European ancestry, 7 were identified in multi-ancestry analyses and 1 was associated with early-onset prostate cancer.

MedicalResearch.com Interview with: Renata Afi Rawlings-Goss, Ph.D. Postdoctoral Fellow Tishkoff Lab, University of Pennsylvania Medical Research: What are the main findings of the study? Dr. Rawlings-Goss: We found genetic mutations in key gene regulators that have been linked to ethnic disparities in cancer. Our investigation identified more than 30 previously undescribed mutations in important regulatory molecules called microRNAs. Individual microRNA molecules can regulate large numbers of genes in some cases over 6000 genes at once. Therefore, mutations in these genes have been linked to numerous diseases. By and large, however, microRNA mutations have not been studied in people of diverse ethnic backgrounds.

Dr Marc Tischkowitz MD PhD University Lecturer (Associate Professor) and Honorary Consultant Physician in Medical Genetics Department of Medical Genetics, University of CambridgeMedicalResearch.com Interview with: Dr Marc Tischkowitz MD PhD University Lecturer (Associate Professor) and Honorary Consultant  Physician in Medical Genetics Department of Medical Genetics, University of Cambridge Medical Research: What are the main findings of the study? Dr. Tischkowitz: The PALB2 gene was first identified in 2006 and linked to breast cancer in 2007 but until now we have not had good breast cancer risk estimates for women who have inherited PALB2 mutations. This study was started in 2009 by an group of research institutions (The PALB2 Interest Group) in Canada, US, Europe (UK, Belgium, Greece, Italy, Finland) and Australia. We studied 362 individuals with PALB2 mutations from 154 families. We found that awomen with a PALB2 mutation will on average have a 35% risk of developing breast cancer by the age of 70, rising to 58% if there is a strong family history. Our study will help clinicians to better advise and manage such women. There are several new aspects.
  • It is by far the largest study to date and provides the most accurate risk estimates for PALB2 mutation carriers.
  • It shows that the breast cancer risk is modified by the family history.

Dr. Agatha van der Klaauw, PhD Wellcome Trust Postdoctoral Clinical Fellow Wellcome Trust-MRC Institute of Metabolic Science University of Cambridge Metabolic Research Laboratories Addenbrooke's Hospital Cambridge, United KingdomMedicalResearch.com Interview with: Dr. Agatha van der Klaauw, PhD Wellcome Trust Postdoctoral Clinical Fellow Wellcome Trust-MRC Institute of Metabolic Science University of Cambridge Metabolic Research Laboratories Addenbrooke's Hospital Cambridge, United Kingdom   Medical Research: What are the main findings of the study? Dr. van der Klaauw: Obesity occurs when we eat more calories than we burn which is often easy to do as many foods are highly palatable and high in calories. Highly palatable foods such as chocolate trigger signals in the brain that give a feeling of pleasure and reward (sometimes called cravings) which can contribute to overeating. These signals are processed in the reward centres in the brain, where sets of neurons release chemicals such as dopamine. However, very little is known about whether the reward centres of the brain work differently in some people who are overweight. In this study, we were interested in studying overweight people who had a problem with the melanocortin 4 receptor (MC4R) gene. About 1% of obese people have a problem in this gene which contributes to weight gain from a young age. We compared three groups of people: people who were overweight due to a problem in the MC4R gene, people who were overweight but the gene was normal and some people who were normal weight. We performed functional Magnetic Resonance Imaging (fMRI) scans to look at how the reward centres in the brain were activated by pictures of appetizing food such as chocolate cake compared to bland food such as rice or broccoli and non-food items such as staplers. We found that in normal weight people, the reward centres are activated (light up) when they are shown pictures of cake or chocolate and the same was seen in overweight people with a problem in the MC4R gene. But we found that the reward centres were underactive in overweight volunteers (in whom the gene was normal).

Kaminsky, Ph.D. Assistant Professor Johns Hopkins University School of Medicine Department of Psychiatry Baltimore, MD, 21205 Medical Research: What are the main findings of the study? Dr. Kaminsky: A DNA methylation increase at the SKA2 gene was identified and observed across three post mortem brain tissue cohorts and was associated with suicide. The DNA methylation at the SKA2 gene was associated with lower gene expression of the gene. The same association was found in blood allowing us to attempt to predict suicidal behaviors in living individuals.

Dr. Daniel AgardhMedicalResearch.com Interview with: Dr. Daniel Agardh M.D., Ph.D Department of Pediatrics Diabetes and Celiac Disease Unit Skåne University Hospital Malmo, Sweden, MedicalResearch: What are the main findings of the study? Dr. Agardh: In this study, we stratify the risk of celiac disease among children according to their HLA genotype and country of residence. We confirm that HLA-DQ2/2 genotype is the major risk factor for early celiac disease, but also show how the risk differs between the participating countries despite of sharing similar HLA risk. This points to the direction of an interaction between HLA and the environment that eventually lead to an autoimmune response in genetic susceptible children.

Michele Jacob, Ph.D. Professor of Neuroscience Sackler School of Graduate Biomedical Sciences Tufts UniversityMedicalResearch.com Interview with Michele Jacob, Ph.D. Professor of Neuroscience Sackler School of Graduate Biomedical Sciences Tufts University MedicalResearch: What are the main findings of the study? Dr. Jacob: Autistic-like behaviors and cognitive impairments associate with loss of the Adenomatous Polyposis Coli (APC) gene.  We deleted APC chiefly from excitatory neurons in the mouse developing forebrain; the mice exhibited changes in synapse maturation and density, reduced social interest, increased repetitive behaviors, and learning deficits.  In addition, we found  molecular changes that define a novel role for APC in linking to and regulating the levels of particular proteins that function in synaptic adhesion complexes and signaling pathways that are required for normal learning and memory consolidation.

Monika Waszczuk 1+3 PhD Student MRC SGDP Research Centre Institute of Psychiatry, King's College London DeCrespigny Park London UKMedicalResearch.com Interview with: Monika Waszczuk 1+3 PhD Student MRC SGDP Research Centre Institute of Psychiatry, King's College London DeCrespigny Park London UK MedicalResearch: What are the main findings of the study? Answer: Little is known about the genetic influences on the relationship between depression and anxiety disorders across development. We used two population-based prospective longitudinal twin and sibling studies to investigate phenotypic associations between the symptoms of these disorders, and tested genetic structures underlying these symptoms across three developmental stages: childhood, adolescence and early adulthood. We found that depression and anxiety disorder symptoms are largely distinct in childhood and are influenced by largely independent genetic factors. Depression and anxiety symptoms become more associated and shared most of their genetic etiology from adolescence. An overarching internalizing genetic factor influencing depression and all anxiety subscales emerged in early adulthood. These results provide preliminary evidence for different phenotypic and genetic structures of internalizing disorder symptoms in childhood, adolescence and young adulthood, with depression and anxiety becoming more associated from adolescence.

Dr. Anders Nykjaer MD, PhD Mayo Clinic in Florida and Aarhus University in DenmarkMedicalResearch.com Interview with: Dr. Anders Nykjaer MD, PhD Mayo Clinic in Florida and Aarhus University in Denmark MedicalResearch: What are the main findings of the study? Dr. Nykjaer: It is well known that ADHD is a complex condition caused by a number of factors including genetic and environment. However, approximately 75% etiology is considered to be genetic and a large body of investigations suggests that it is multiple genes each with a moderate effect that is responsible for conferring susceptibility to ADHD. We have here found one single gene the dysfunction of which is sufficient to trigger the disease.  The gene encodes a receptor, SorCS2, which ensures correct wiring our reward system during embryonic development. Malfunction of the receptor causes ADHD-like symptoms in mice. It is well accepted that ADHD predisposes to psychiatric disorders and genetic reports have linked variations in the SorCS2 gene with schizophrenia. Studies are currently ongoing to evaluate if mutations disrupting the function of SorCS2 may also result in schizophrenia. If this is the case we have come closer to an explanation for the link between ADHD and psychiatric disorders. In the future when prenatal genetic screening becomes established, non-sense mutations in the SorCS2 gene can be used to predict that the child will develop ADHD with 100% certainty.

Rosenzweig, MD, PhD Director, Primary Immunodeficiency Clinic (PID-C) Head of the Infectious Diseases Susceptibility Unit at the Laboratory of Host Defenses, National Institutes of Allergy and Infectious Diseases National Institutes of Health Bethesda, MD, 20892 MedicalResearch.com: What are the main findings of the study? Dr. Rosenzweig: We diagnosed a disease called CDG-IIb in two siblings with severe development issues and very low levels of immunoglobulins, which include infection-fighting antibodies. These children were referred to the NIAID Primary Immunodeficiency Clinic through the NIH Undiagnosed Diseases Program. CDG-IIb is an extremely rare congenital disorder of glycosylation (CDG), with only one other case reported. The genetic defect of the disease disrupts glycosylation, the process for attaching and trimming sugars from proteins. Almost 50% of our proteins have sugars attached, and these are called glycoproteins. They include immunoglobulins and also some viral glycoproteins that are made when cells are infected by a virus. The spread of some viruses, including HIV and influenza, depend on viral glycoproteins in order to infect additional cells and form viral protective shields. We found that this type of virus was less able to replicate, infect other cells, or create adequate protective shields in CDG-IIb patient cells because of the glycosylation defect. In comparison, adenovirus, poliovirus, and vaccinia virus, which either do not rely on glycosylation or do not form protective glycoprotein shields, replicated normally when added to both CDG-IIb and healthy cells.

Dr. Panos N. Papapanou: Professor of Dental Medicine; Chairman, Section of Oral and Diagnostic Sciences Director, Division of Periodontics Section of Oral and Diagnostic Sciences, College of Dental Medicine, Columbia University, New York, NY, USAMedicalResearch.com Interview with: Dr. Panos N. Papapanou: Professor of Dental Medicine; Chairman, Section of Oral and Diagnostic Sciences Director, Division of Periodontics Section of Oral and Diagnostic Sciences, College of Dental Medicine, Columbia University, New York, NY MedicalResearch.com: What are the main findings of the study? Dr. Papapanou: Gene expression signatures in gum tissues obtained from patients with periodontitis identified two fairly robust clusters, suggesting potential differences in pathobiologic processes between the two groups. In addition, the two clusters displayed differences in important features of the disease (e.g., the extent and severity of periodontitis, and the level of colonization by periodontal bacteria). These findings indicate that gene expression patterns may form the basis for a novel, pathobiology-based classification of periodontitis.

Dr. Azi Gazdar, MD UT Southwestern Medical Center W. Ray Wallace Distinguished Chair in Molecular Oncology Research Hamon Center for Therapeutic Oncology, PathologyMedicalResearch.com Interview with: Dr. Azi  Gazdar, MD UT Southwestern Medical Center W. Ray Wallace Distinguished Chair in Molecular Oncology Research Hamon Center for Therapeutic Oncology, Pathology MedicalResearch.com: What are the main findings of the study? Dr. Gazdar: We describe the characteristics of lung cancers arising in subjects who inherited a germline mutation that predisposes to lung cancer.  The mutation is rare in the general populations, and is inherited equally by both sexes.  However it is a potent predisposing gene, and one third of the never smoking carriers will develop lung cancer.  Thus, about 1% of patients who develop lung cancer carry the germline mutation.  This figure may rise as awareness of the condition and its link to lung cancer is raised among doctors diagnosing lung cancer. However, lung cancers mainly develop in women who are lifetime never smokers.  Lung cancer development is much less common among smokers and men, although accurate figures are not yet available. So the risk among carriers is somewhat similar to the BRCA genes predisposing to breast cancer, where a female carrier has about a 50% lifetime chance of developing breast cancer. The specific germline mutation (known as T790M) occurs in a gene known as epidermal growth factor receptor (EGFR) gene.  Sporadic mutations in this gene usually predict for effective responses to a class of drugs known as tyrosine kinase inhibitors (TKIs), which are widely used in the treatment of lung cancer.  However, the T790M mutation, when it occurs in sporadic tumors not associated with germline inheritance are resistant to TKI therapy.  Thus the prediction is that lung cancers arising in carriers with the germline mutation would also be resistant to TKI therapy.

dr_cristen_j_willerMedicalResearch.com Interview with: Cristen J. Willer, PhD Assistant Professor Division of Cardiovascular Medicine, Dept of Internal Medicine Dept of Human GeneticsDept of Computational Medicine and Bioinformatics University of Michigan Ann Arbor, MI 48109-5618 MedicalResearch.com: What are the main findings of the study? Dr. Willer: We wanted to find new genes related to heart disease, so we examined the DNA of approximately 10,000 Norwegian individuals and found 10 genes that are important regulators of blood cholesterol levels. Nine of these were well known to be related to lipids, but one gene was new.  It turned out to be in a region we'd previously noticed to be related to cholesterol, but it was a big region and we hadn't been able to pinpoint the gene yet.  Using this new approach, focusing on DNA differences that result in slightly different proteins in people, we zeroed in on the gene.  We then altered this gene in mice, and saw the predicted changes in cholesterol levels in mice.

Dr. Lu Qi: In this study, we for the first time provide reproducible evidence from three large cohort studies to show that the association between regular consumption of fried foods and higher BMI was particularly pronounced among people with a greater genetic predisposition to obesity. On the other hand, the adverse genetic effects on BMI were also amplified by consuming more fried foods, the effects among those who ate fried foods more than four times a week was about twice as large compared with those who ate them less than once a week.

Henry R. Kranzler, MD Professor, Department of Psychiatry Director of the Center for Studies of Addiction. University of Pennsylvania Perelman School of Medicine, PhiladelphiaMedicalResearch.com Interview with: Henry R. Kranzler, MD Professor, Department of Psychiatry Director of the Center for Studies of Addiction. University of Pennsylvania Perelman School of Medicine, Philadelphia MedicalResearch.com: What are the main findings of the study? Dr. Kranzler: The study had two main findings:
  • First, topiramate, at a maximal dosage of 200 mg/day, which is lower than the 300 mg/day used in prior treatment trials, substantially reduced the frequency of heavy drinking and increased the frequency of abstinent days more than placebo. The lower dosage was well tolerated.
  • Second, a variant in a gene that encodes a receptor subunit that binds topiramate moderated the response to topiramate. That is, C-allele homozygotes in the single nucleotide polymorphism rs2832407 in GRIK1, the gene encoding the GluK1 subunit of the kainate receptor, were the subgroup that accounted for the effects of topiramate on heavy drinking. This has important implications for the personalized treatment of alcohol use disorder, in that 40% of people of European ancestry have this genotype and, if confirmed, these findings would make it possible to screen people genetically to select an effective treatment.

Dr. Lacourse: The gene-environment analyses revealed that early genetic factors were pervasive in accounting for developmental trends, explaining most of the stability and change in physical aggression, ” Lacourse said. “However, it should be emphasized that these genetic associations do not imply that the early trajectories of physical aggression are set and unchangeable. Genetic factors can always interact with other factors from the environment in the causal chain explaining any behaviour.”

Linda Brzustowicz, M.D. Professor and Chair Department of Genetics Rutgers University Piscataway, NJ 08854MedicalResearch.com Interview with: Linda Brzustowicz, M.D. Professor and Chair Department of Genetics Rutgers University,Piscataway, NJ 08854 MedicalResearch.com: What are the main findings of the study? Dr. Brzustowicz: The objective of this study was to search for locations in the human genome that impact language ability in individuals with autism as well as in their family members without autism.  To do this, we recruited families with an individual with autism and at least one other family member without autism but with a language learning impairment.  We identified two locations in the human genome that are linked to language ability in these families.  Importantly, these locations do not appear to be specific to language impairment in the individuals with autism, but are related to language ability in other family members as well.  This suggests that while individuals with autism may have new, or de novo, genetic variations that are important for risk of illness, they may also carry inherited genetic variation that influence the expression of their illness.  The effects of these inherited variants can also be seen in the language performance of family members without autism.

Dr. Rebecca Todd Assistant Professor University of British Columbia Department of Psychology Centre for Interactive Research on Sustainability 4342A-2260 West Mall Vancouver, BC V6T 1Z4MedicalResearch.com Interview with: Dr. Rebecca Todd Assistant Professor University of British Columbia Department of Psychology Centre for Interactive Research on Sustainability 4342A-2260 West Mall Vancouver, BC V6T 1Z4 MedicalResearch.com: What are the main findings of the study? Answer: What we found, in essence, is that some individuals are genetically predisposed to see the world more darkly than others. We find that a common gene variant is linked to perceiving emotional events --especially negative ones --¬ more vividly than others. This gene variant has been previously linked (by other researchers) to emotional memory and the likelihood of experiencing intrusive, or “flashback” memories following traumatic experience. Our findings suggest that in healthy young adults this enhanced emotional memory may be because individuals are more likely to perceive what’s emotionally relevant in the first place. We've all heard of rose colored glasses, but this is more like gene-colored glasses, tinted a bit darkly.

Nguyen Osteoporosis and Bone Biology Program Garvan Institute of Medical Research 384 Victoria Street, Darlinghurst NSW 2010 Australia MedicalResearch.com: What are the main findings of the study? Dr. Nguyen: We analyzed polymorphisms of the FTO (fat mass and obesity) gene in 934 elderly women of Caucasian background, and found that carriers of minor genotype (AA) of the SNP rs1121980 had a two-fold increase in the risk of hip fracture compared with carriers of major genotype (GG). Approximately 20% of women are carriers of the AA genotype. We estimate that about 17% of hip fracture cases could be attributed to the variation within the gene.
