Sequencing Strategies for Population and Cancer Epidemiology Studies (SeqSPACE) Webinar Series
The Epidemiology and Genomics Research Program hosts a webinar series entitled "Sequencing Strategies for Population and Cancer Epidemiology Studies (SeqSPACE)." The purpose of this forum is to provide an opportunity for our grantees and other interested individuals to share lessons learned and practical information regarding the application of next generation sequencing to cancer epidemiology studies.
By sharing lessons learned across funded projects, EGRP aims to facilitate higher quality research and more interpretable genetic research studies for the future. In addition, the webinar participants may work together to establish best practices for epidemiology research.
Any interested individual is invited to participate, however pre-registration is required. Each presentation will be about 30 minutes in length and allow for 30 minutes of discussion. Instructions for connecting to the webinars will be sent via e-mail to individuals who register for the webinars.
The past decade has seen a transformation in genetic epidemiology of complex diseases, from linkage to association studies, which progressed from investigating single variants in candidate genes, to genome-wide approaches, including genome-wide association studies (GWAS). GWAS have successfully identified hundreds of common genetic variants associated with cancer and other complex diseases, however with the advent of next-generation parallel DNA sequencing technologies, there is a renewed interest in examining the role of rare variants and other forms of genetic variation in complex disease etiology. While sequencing of thousands of cancer-normal genomes is estimated to be completed worldwide by the end of 2014, germline sequencing in epidemiologic studies of cancer risk are relatively nascent.
Sequencing technology is more technically difficult than genotyping using GWAS arrays and requires unique considerations related to the study design and techniques used for sequencing and analysis. Quality control standards are needed for sequencing across samples, platforms, and institutions. GWAS arrays had high reproducibility and concordance, but this is not yet the case for sequencing data. In addition, combining data from different studies is more challenging in sequencing studies than GWAS. Poorly designed studies will result in uninterpretable or even biased results.
