3 Target Enrichment: A Highly Enabling Process What? Also referred to as genome partitioning, targeted re-sequencing, DNA capture Captures genomic material of interest for next generation sequencer (i.e. Illumina, SOLiD, 454 etc ) gdna Why? Sequence your regions of interest! Enables focus on a subset of the genome Saves both time and money for downstream sequencing Enriched library Identify homozygous and heterozygous variants in targets relative to the reference genome Page 3

12 Exon Capture is a Powerful Tool to Study Mendelian Diseases Mendelian diseases are caused by coding mutations (with some exceptions) Exons are only ~1-1.4 % of human genome (30-50Mb) Primarily protein coding regions Advantages: Much less sequencing ~5% of WGS, so up to 20x more samples All Exons on X chromosomes 7674 exons 3 Mb Why coding? More interpretable Easier to follow up Especially adapted to study of Mendelian diseases CCDS exons v1 CCDS + RefSeq 38 Mb v2 (Broad) GENCODE 50 Mb (Sanger) Includes ncrna Page 13

28 Inherited loss-of-function mutations in the tumor suppressor genes BRCA1, BRCA2, and multiple other genes predispose to high risks of breast and/or ovarian cancer. Cancerassociated inherited mutations in these genes are collectively quite common, but individually rare or even private. To determine whether massively parallel, next-generation sequencing would enable accurate, thorough, and cost-effective identification of inherited mutations for breast and ovarian cancer, we developed a genomic assay to capture [with Agilent s custom SureSelect], sequence, and detect all mutations in 21 genes, including BRCA1 and BRCA2, with inherited mutations that predispose to breast or ovarian cancer. There were zero false-positive calls of nonsense mutations, frameshift mutations, or genomic rearrangements for any gene in any test sample. This approach enables widespread genetic testing and personalized risk assessment for breast and ovarian cancer. Page 31

Variant SNPs were also detected at high rates (99 percent) for both the C3H and DBA samples. B) Of the SNPs detected, concordance with the Perlegen Mouse SNP data set for both the C3H ad DBA samples was 98 percent for the variants and 95 percent overall.
