Despite the limitation generic 250mg eulexin with mastercard mens health france, impact of genomic analysis on cardiovascular research is already visible buy eulexin 250mg amex prostate oncology 21st. New genes of cardiovascular interest have been discovered, while a number of known genes have been found to be changed in unexpected contexts. The patterns in the variation of expression of many genes correlate well with the models currently used to explain the pathogenesis of cardiovascular diseases. Much more work has yet to be done, however, for the full exploitation of the immense informa- tive potential of cardiovascular genomics. Meanwhile, cardiovascular system is receiving its due share of interest in genomics-based drug discovery and develop- ment in the commercial sector. Universal Free E-Book Store Introduction 481 Universal Free E-Book Store 482 14 Personalized Management of Cardiovascular Disorders Role of Diagnostics in Personalized Management of Cardiovascular Disease Cardiovascular Disorders with a Genetic Component Several cardiovascular diseases are recognized to have a genetic component; indeed, a family history of heart disease has always attracted the physician’s attention. In recent years, molecular genetics has contributed to the development of molecular cardiology, opening up some new pathways to the diagnosis, prevention, and treat- ment of some cardiovascular diseases. This disease reﬂects a defect in the electrical properties of the cardiac muscle, which predisposes the patient to life-threatening ventricular ﬁbrillation after stress. Five genes have been identiﬁed where the mutations are associated with this disorder. If a genetic mutation is detected, its type and location can assist the physician in making treatment selections that could include life-style modiﬁcation, prescription or avoidance of speciﬁc classes of drugs or the implanta- tion of a deﬁbrillator. A patient’s family members also beneﬁt from the test because it can identify if they inherited the same mutation as the initially symptomatic patient and may be at risk of a potentially fatal arrhythmia. Sequencing of the protein-coding regions of the human genome, the exome, has the potential to identify rare mutations that have a large Universal Free E-Book Store Universal Free E-Book Store 484 14 Personalized Management of Cardiovascular Disorders effect on phenotype. Protein-coding regions of genes in participants of European or African ancestry in the Exome Sequencing Project were sequenced to determine whether rare mutations in coding sequence, individually or in aggregate within a gene, were associated with plasma triglyceride levels (Crosby et al. Approximately 1 in 150 persons in the study was a heterozygous carrier of at least one of these four mutations. Identifying those at high risk for sudden cardiac death before fatalities occur has been challenging, both at the clinical and at the genetic level. In more than one third of all cases, sudden cardiac death is the ﬁrst hint of heart disease. It is widely believed that many factors, genetic and environmental, contribute to irregular heart- beat and other conditions that may lead to sudden cardiac death. Being able to identify predisposed individuals can save their lives by prescribing beta-blockers and other drugs that regulate heart rhythm, and even by implanting automatic deﬁ- brillators in those with the highest risk. It is now licensed by clinical labora- tory of Aurora Health Care in Milwaukee, Wisconsin. The authors developed a complemen- tary data analysis pipeline to select and prioritize genetic variants. The overall pro- cedure can screen a large number of target genes simultaneously, thereby potentially revealing new disease-causing and modiﬁer genes. By using this procedure, hyper- trophic cardiomyopathy patients can be analyzed in a shorter time and at a lower cost than with current procedures. Illumina iSelect Custom Genotyping BeadChip can be used to study the genetic diversity of pathways for >2,000 genes that are linked to vascular conditions including hypertension, myocardial infarc- tion, heart failure, stroke, insulin resistance, metabolic disorders, dyslipidemia, and inﬂammation. The microarray will enable research- ers to quickly genotype thousands of patients across thousands of genes to identify genetic risk factors underlying vascular diseases and other complex genetic traits.
