Advances in clinical genetic testing has led to increased insight into the human genome, including how challenging it is to interpret rare genetic variation. In some cases, the ability to detect genetic mutations exceeds the ability to understand their clinical impact, limiting the advantage of these technologies. Obstacles in genomic medicine are many and include: understanding the level of certainty/uncertainty behind pathogenicity determination, the numerous different variant interpretation-guidelines used by clinical laboratories, delivering the certain or uncertain result to the patient, helping patients evaluate medical decisions in light of uncertainty regarding the consequence of the findings...

Long QT syndrome (LQT) is a pro-arrhythmogenic condition with life threatening complications. Fifteen genes have been associated with congenital LQT however, the genetic causes remain unknown in more than 20% of cases. Eighteen patients with history of palpitations, presyncope, syncope and prolonged QT were referred to the Yale Cardiovascular Genetics Program. All subjects underwent whole exome sequencing (WES) followed by confirmatory Sanger sequencing. Mutation burden analysis was carried out using WES data from sixteen subjects with no identifiable cause of LQT...

In the 15 years following the release of the first complete human genome sequences, our understanding of rare and common genetic variation as determinants of cardiovascular disease susceptibility, prognosis, and therapeutic response has grown exponentially. As such, the use of genomics to enhance the care of patients with cardiovascular diseases has garnered increased attention from clinicians, researchers, and regulatory agencies eager to realize the promise of precision genomic medicine. However, owing to a large burden of "complex" common diseases, emphasis on evidence-based practice, and a degree of unfamiliarity/discomfort with the language of genomic medicine, the development and implementation of genomics-guided approaches designed to further individualize the clinical management of a variety of cardiovascular disorders remains a challenge...

The development of high-throughput technologies such as next-generation sequencing (NGS) has allowed for thousands of DNA loci to be interrogated simultaneously in a fast and economical method for the detection of clinically deleterious variants. Whenever a clinical diagnosis is known, a targeted NGS approach involving the use of disease-specific gene panels can be employed. This approach is often valuable as it allows for a more specific and clinically relevant interpretation of results. Here, we describe the customization, validation, and utilization of a commercially available targeted enrichment platform for the scalability of clinical diagnostic cardiovascular genetic tests, including the design of the gene panels, the technical parameters for the quality assurance and quality control, the customization of the bioinformatics pipeline, and the post-bioinformatics analysis procedures...

In the last decade, an increasing number of cardiac conditions have been shown to have a genetic basis. Cardiovascular genetic counseling has emerged as a subspecialty aiming to identify unaffected at-risk individuals. An important sector of this at-risk population also includes expectant mothers, in whom unique clinical challenges may arise. Genetic counselors, especially those in cardiovascular and prenatal settings, have an opportunity to identify and assist women who may benefit from cardiovascular care during pregnancy...

AIMS: Pro- and anti-inflammatory cytokines play a significant role in early atherosclerosis. Linkage disequilibrium patterns differ between ethnic groups pointing toward the need to develop population-specific gene risk scores. Our objective was to investigate the role of a cytokine gene score in the risk prediction of premature coronary artery disease (PCAD). METHODS: A case-control study was performed at the National University of Sciences and Technology (NUST) in collaboration with the Cardiovascular Genetics Institute, University College London, United Kingdom...

Advances in genomics are enhancing our understanding of the genetic basis of cardiovascular diseases, both congenital and acquired, and stroke. These advances include finding genes that cause or increase the risk for childhood and adult-onset diseases, finding genes that influence how patients respond to medications, and the development of genetics-guided therapies for diseases. However, the ability of cardiovascular and stroke clinicians to fully understand and apply this knowledge to the care of their patients has lagged...

Cardiovascular disease (CVD) is a major contributor to morbidity and mortality worldwide. However, the pathogenesis of CVD is complex and remains elusive. Within the last years, systems medicine has emerged as a novel tool to study the complex genetic, molecular, and physiological interactions leading to diseases. In this review, we provide an overview about the current approaches for systems medicine in CVD. They include bioinformatical and experimental tools such as cell and animal models, omics technologies, network, and pathway analyses...

BACKGROUND: Genetic information has the potential to create a more personalised, prompt, early and accurate risk evaluation. The effect of these genetic variants on the serum biomarker levels (phenotype) needs to be studied to assess their potential causal role in the pathogenesis of premature coronary artery disease (PCAD). Objectives were to determine the genotypic distribution of interleukin (IL) 18, tumour necrosis factor-α (TNFA), IL6 and IL10 single nucleotide polymorphisms (SNPs) in Pakistani PCAD cases and disease free controls and to study the effect of these gene polymorphisms on the serum cytokine levels (IL18, TNFA, IL6 and IL10) and cytokine imbalance (IL18:IL10 and TNFA:IL10)...

Management of survivors of cardiac arrest is largely based on a traditional approach. However, during the past decade, arrhythmias of genetic origin have increasingly been recognized as contributing to many more cases than previously appreciated. This realization is forcing physicians managing the survivors of cardiac arrest also to consider family members. In this Perspectives article, we examine the appropriate management approaches for survivors of cardiac arrests related to channelopathies, cardiomyopathies, or ischaemic heart disease, and for their families...

Congenital heart defects (CHDs) are common birth defects and result in significant morbidity and global economic impact. Genetic factors play a role in most CHDs; however, identification of these factors has been historically slow due to technological limitations and incomplete understanding of the impact of human genomic variation on normal and abnormal cardiovascular development. The advent of chromosome microarray (CMA) brought tremendous gains in identifying chromosome abnormalities in a variety of human disorders and is now considered part of a standard evaluation for individuals with multiple congenital anomalies and/or neurodevelopmental disorders...

Inherited cardiovascular (CV) conditions are common, and comprehensive care of affected families often involves genetic testing. When the clinical presentations of these conditions overlap, genetic testing may clarify diagnoses, etiologies, and treatments in symptomatic individuals and facilitate the identification of asymptomatic, at-risk relatives, allowing for often life-saving preventative care. Although some professional society guidelines on inherited cardiac conditions include genetic testing recommendations, they quickly become outdated owing to the rapid expansion and use of such testing...

Cardiovascular researchers and clinicians who analyze next-generation sequencing data often search databases of previously reported mutations to determine if an observed mutation is pathogenic. In 2012 we created a database of all reported mutations causing human dyslipidemia syndromes. In 2015, we were advised that some information in our database was now proprietary, after the acquisition of a human disease genetic database by a private biotechnology company. To make our dyslipidemia database and tables of mutations compliant with this new reality, we wrote custom computer scripts to remove certain data fields from the previously reported tables...

Left ventricular non-compaction (LVNC) is a rare cardiomyopathy, which is today, due to modern ultrasound technology more frequently detected in clinical practice. It is caused by the failure of normal embryonic development of the myocardium from loosely arranged muscle fibers to the mature compacted form of myocardium. Morphologic presentation consists of unique two-layered structure, a thick noncompacted endocardial and a thin compact epicardial layer, in infero-lateral and apical segments. The endocardial layer contains loosely arranged muscle fibers, prominent trabeculations and deep perfused intertrabecular recesses...

BACKGROUND: In spite of progress in cardiovascular genetics, data on genetic background of myocardial infarction are still limited and contradictory. This applies as well to the genes involved in inflammation and coagulation processes, which play a crucial role in the disease etiopathogenesis. METHODS AND RESULTS: In this study we found genetic variants of TGFB1, FGB and CRP genes associated with myocardial infarction in discovery and replication groups of Russian descent from the Moscow region and the Republic of Bashkortostan (325/185 and 220/197 samples, correspondingly)...

Sudden death and stroke afflicted a family from rural Quebec with such frequency as to be called the Coaticook curse by the local community. In Montreal in the late 1950s, a team of physicians led by J.A.P. Paré investigated this family for inherited cardiovascular disease. Their efforts resulted in an extensive and now classic description of familial hypertrophic cardiomyopathy. A quarter of a century later, the same family was the subject of linkage analysis and direct sequencing, culminating in the isolation of a mutation in the gene encoding the β myosin heavy chain...
