Genome Wide Association

 

Human SNP Genome Wide Association Studies (GWAS) can be accomplished using a variety of arrays appropriate for a wide breadth of study design needs.

 

Released data includes raw data files (.idat files), genotypes, quality scores, intensity values, SNP and sample summary tables including quality flags and comments, and SNP cluster definition files.


We are pleased to announce that CIDR has entered into a collaboration with the University of Washington Center for Biomedical Statistics (CBS). Plate map design, GWAS data cleaning and dbGaP posting, imputation of GWAS datasets to 1000 Genomes, and detection of chromosomal anomalies are new services offered at NO ADDITIONAL COST to study investigators with GWAS projects supported by the NIH CIDR Program. Investigators working with CIDR through the SNP Center may also utilize these services through a fee-for-service mechanism.


Under the NIH CIDR Program, a single application can be submitted for both the initial GWAS study as well as replication using our custom SNP service. Investigators are required to have all samples collected and all subjects phenotyped before applying.
