question: List uniparental disomy (UPD) detection algorithms
answer: UPDtool and AsCNAR are tools for detecting uniparental disomy (UPD). UPDtool is a computational tool for detection and classification of uniparental disomy (UPD) in trio SNP-microarray experiments. AsCNAR (allele-specific copy-number analysis using anonymous references) detects the copy-number neutral LOH, or uniparental disomy (UPD), in a large number of acute leukemia samples.
