MicroArray - Affymetrix SNP

Analysis of both SNP and CNV made possible through 906K SNP probe and 946k CNV probbe equipped Affymetrix SNP Array. 

Overview 

More than 906,600 SNPs:

Unbiased selection of 482,000 SNPs; historical SNPs from the SNP Array 5.0

Selection of additional 424,000 SNPs
- Tag SNPs
- SNPs from chromosomes X and Y
- Mitochondrial SNPs
- New SNPs added to the dbSNP database
- SNPs in recombination hotspots
 

More than 946,000 copy number probes:

202,000 probes targeting 5,677 CNV regions from the Toronto Database of Genomic Variants

744,000 probes, evenly spaced along the genome

Detected 10 times more copy number changes than other SNP/CN platforms

Three times more coverage of CNPs; only platform with non-polymorphic probes

GTC 3.0 leverages new, high-resolution reference map and CNP calling algorithm developed by the Broad Institute
