Genotyping and Genetics for Population Sciences Core
The DF/HCC Genotyping and Genetics for Population Sciences Core provides flexible, high-quality, high-throughput single nucleotide polymorphisms (SNP) genotyping to the DF/HCC research community. Its mission is to provide services to DF/HCC members conducting molecular analyses of germline and somatic DNA collected as part of a wide range of investigations into the molecular epidemiology of cancer, including Genome Wide Association Studies (GWAS). This core provides high-throughput assays of specific gene mutations and SNPs in the many situations where previously defined specific nucleotide alterations are of interest.
- SNP analysis using Taqman
- SNP analysis using the Taqman OpenArray Genotyping System
- Targeted sequencing using Ion Torrent PGM
- DNA extraction, plating, and whole genome amplification
- SNP analysis and sequencing using Illumina technologies
- Telomere length analysis
Project Title: Aspirin use, 8q24 single nucleotide polymorphism rs6983267, and colorectal cancer according to CTNNB1 alterations
Principal Investigator: Andrew Chan, MD, MPH (MGH)
Description of the Project: The results support an influence of aspirin on WNT/CTNNB1 signaling andsuggest that aspirin chemoprevention may be tailored according to rs6983267 genotype.
Contribution of the Core: The Core performed DNA Extraction of 5,233 individuals and TaqMan and OpenArray genotyping on 5,233 individuals.
Project Title: Common genetic variation of the calcium-sensing receptor and lethal prostate cancer risk
Principal Investigator: Edward Giovannucci, MD, ScD (HSPH)
Description of the Project: The joint association of SNPs in the calcium-sensing receptor (CaSR) was significant for lethal Prostate Cancer (P = 0.04). The findings indicate that the CaSR may be involved in Prostate Cancer progression.
Contribution of the Core: The Core performed OpenArray genotyping and DNA extraction and whole genome amplification of 2,924 individuals.
Project Title: Plasma vitamin D biomarkers and leukocyte telomere length
Principal Investigator: Immaculata DeVivo, MPH, PhD (BWH)
Description of the Project: Higher plasma 25(OH)D levels may be associated with longer telomeres, and this association may be modified by calcium intake.
Contribution of the Core: The Core performed DNA Extraction of 1,424 individuals, Telomere Length Analysis on 1,424 individuals and OpenArray genotyping on 480 individuals.
