MethodSNP array
AnalysisLarge CNV discovery was accomplished by using HMMSeg, considering both the `LogR ratio' and `B-allele frequency' data for each sample simultaneously. We used a four-state model, one each for null (homozygous deletion), hemizygous deletion, diploid and amplification. Initial segmentation results were merged and filtered, requiring all variants to be larger than 1 kb in length and to span at least 10 probes for amplifications or hemizygous deletions, or 3 probes for homozygous deletions. We then used a combination of paired-end sequence maps, oligo array-CGH, and variant resequencing (described in Kidd et al. 2008) to support the calls.
