Hi Michael, Sorry for the very late reply. As you probably know most methods infer regions of LOH using Hidden Markov Models on genotype calls. In terms of software, you are probably aware of dChipSNP, which is certainly a good candidate. I am not sure whether Birdsuite from the Broad explicitly

Hi Pierre, thanks for the offer. In the one project, we are looking into genetic causes for Silver-Russel syndrome. So far, we have identified only few recurring CNAs. However, one goal is to screen patients for UPDs (that is, copy number neutral LOH), too; some regions (e.g. chromosome 7) have b

Hi, there are no methods of such analysis available in aroma.affymetrix, and there is no time line for implementing that. It is of course on our wishlist, though. Note also that "LOH analysis" is rather unspecific; there are many different ways to infer LOH, of which some depend on what kind of
