Newborn Screening for Genetic Susceptibility to Type 1 Diabetes and Celiac Disease and Prospective...
Type1diabetesCeliac DiseaseThis is an observational study, in which newborn infants from the general population are screened at birth for HLA-conferred susceptibility to type 1 diabetes and celiac disease. The participants carrying genetic susceptibility to type 1 diabetes (approximately 9.5%) will be analyzed for diabetes-associated autoantibodies at the age of 1, 2 and 3 years, while those predisposed to celiac disease (about 14%) will be screened for tissue transglutaminase antibodies at the age of 1 and 3 years. The intention is to screen annually 10,400 newborn infants for a period of 3 years. About 988 infants are each year identified as a child at risk for type 1 diabetes, and it is expected that around 80% of the families with such a child are willing to join the autoantibody screening. Approximately 1456 infants are each year recognized as a child at risk for celiac disease, and again the expectation is that 80% of the families will join the antibody screening program.
Sequence Variations of Genes in the Estrogen Pathway and Perinatal Depression
Postnatal DepressionGenetic PredispositionTo elucidate the disease pathway of perinatal depression by identifying genetic variants which could play a role in predisposing to the condition and/or lead to better understanding of the pathogenesis of the condition. This is achieved by investigating for associations between oestrogen receptor genetic variants and perinatal depression.
Genetic Susceptibility to Lung Cancer in Never Smokers
Lung CancerThe purpose of this study is to help us better understand the cellular changes that may lead to the development of lung cancer. We want to compare people who have never smoked and yet have been diagnosed with lung cancer to never smokers who have not developed lung cancer. We hope to use the information obtained in this study as the basis for future studies and will not regard the results from this study as final.
Universal- Versus Guidelines-Directed Genetic Testing for Germline Pathogenic Variants Utilizing...
Genetic PredispositionThe investigators aim to study the pattern and frequency of pathogenic variants among ALL newly diagnosed cancer patients in a genetically distinct population. Additionally, the investigators will study the uptake rate of "cascade family screening", frequency of pathogenic variants and barriers against testing.
NYCKidSeq: Incorporating Genomics Into Clinical Care of Diverse NYC Children
Genetic DiseasesInborn1 moreThe NYCKidSeq program will significantly advance the implementation of genomic medicine, particularly for children, young adults and their families in Harlem and the Bronx. The study will assess the clinical utility of genomic medicine in three broad areas of pediatric disorders, while engaging a range of providers and community advisors to overcome the well-documented barriers to inclusion of underserved and underrepresented populations in genomic research. The study will also include testing, analyzing, and implementing a novel communication tool, Genomic Understanding, Information and Awareness (GUÍA), to facilitate the return of genomic test results. The use of GUÍA will enhance the understanding of these genomic testing results by families, patients, and care providers at all levels of expertise, in two health systems. Healthcare system leadership will be engaged to provide insights into their readiness for genomic implementation. Overall, the NYCKidSeq program will inform the genomics and clinical communities about how to implement genomic medicine in a diverse population in a clinically useful, technologically savvy, culturally sensitive, and ethically sound manner.
Blood Pressure Lowering Effect of B-vitamins in Adults With a Genetic Pre-disposition to Elevated...
Blood PressureApproximately 12% of the world's population have a have a common C677T polymorphism in the gene encoding the folate metabolising enzyme, methylenetetrahydrofolate reductase (MTHFR). Homozygosity for the polymorphism (TT genotype) causes an increased requirement for the B-vitamins folic acid and riboflavin and more importantly results in an increased risk of developing high blood pressure (BP). Previous work from our Centre has demonstrated significantly higher BP in those with the TT genotype. This work has been conducted in cohorts with premature cardiovascular disease (CVD) and hypertension without overt CVD, but the effect in younger, healthier individuals is unexplored. To date our studies have also focused on BP as the primary outcome, but newer markers of vascular health including central pressure and hemodynamics have emerged as superior prognostic indicators of CVD. The effect of the TT genotype on these measures is an area for investigation and may help us understand the mechanism linking the genotype with BP, which is currently unknown. As adults with the TT genotype have increased requirements for riboflavin and folic acid, and BP in TT adults appears to be riboflavin dependent, the influence of these vitamins on central measures is an area for consideration. Study Design This is an observational study investigating the blood pressure profiles of healthy adults aged 18-65 years, stratified by MTHFR genotype. Apparently healthy adults will be recruited from workplaces and the general community across Northern Ireland and screened for the polymorphism via buccal swab. Those with the TT genotype and a similar number of non-TT (i.e. CC/CT) genotype individuals will be contacted and asked to come to a one-off appointment. Brachial BP will be assessed by an electronic BP monitor, central BP and central haemodynamics (augmentation index, augmentation pressure and pulse wave velocity) will be assessed by SphygmoCor XCEL. In addition, anthropometric measurements, health and lifestyle infromation and a blood sample will be obtained. Data will be statistically analysed using SPSS software to if determine differences between gentoype groups exist.
Early Detection of GEnetic Risk (EDGE)
Genetic PredispositionThe study intervention involves having patients complete a familial cancer risk assessment survey. Those who are found to be at high risk will be offered genetic testing for a panel of hereditary cancers. A "previvor" plan will be created to assist patients and their providers in completing the appropriate follow-up for those with a mutation identified.
A Prognosis and Predicting Genetic Study of Lung Cancer
Lung CancerGenetic Predisposition to DiseaseLung cancer is a leading cause of cancer mortality among adults worldwide. The incidence rates of lung cancer among never smoking females in some parts of East Asia are among the highest in the world. The adenocarcinoma of lung being the most frequently identified histological type is more weakly associated with smoking, and often occurs in females and never-smokers. Although family history of lung cancer has been associated with histological subtypes, the inherited susceptibility factors that affect specific histology are unknown. Genetic factors that determine individual predisposition to lung cancer have been identified via genome-wide association studies. These known common loci, however, explain only a small fraction of the familial risk of lung cancer. The hypothesis of this study is that there are genetic factors that confer inherited susceptibility among patients with primary non-small-cell lung cancer (NSCLC).
