Identifying early events in homocysteine metabolism through methylation map genes may prevent fatality. Materials & methods In the present study, we investigated the role of variants in methylation map genes in ethnically matched 480 individuals that can influence the homocysteine levels and promote development of aneurysm. Results The study demonstrates that the genetic variants in folate cycle and methionine cycle genes such as MTHFR, MTRR, MTR, BHMT and DNMT1 are associated with the risk of aneurysm. Conclusion The associated allelic variants in these genes have functional relevance and are predictive of decreased expression indicative of altered methylation levels that may result in elevated homocysteine.Clinical trials provide evidence essential for progress in health care, and as the complexity of medical care has increased, the demand for such data has dramatically expanded. Conducting clinical trials has also become more complicated, evolving to meet increasing challenges in delivering clinical care and meeting regulatory requirements. Despite this, the general approach to data collection remains the same, requiring that researchers submit clinical data in response to study treatment protocols, using precisely defined data structures made available in study-specific case report forms. Currently, research data management is not integrated within the patient's clinical care record, creating added burden for clinical staff and opportunities for error. During the past decade, the electronic health record has become standard across the US healthcare system and is increasingly used to collect and analyze data reporting quality metrics for clinical care delivery. Recently, electronic health record data have also been used to address clinical research questions; however,
