A pair of Nature papers (PubMedIDs: 18668039, 18668038) find that mapping the risk of schizophrenia to the genome is more readily achieved when examining structural variation (insertions, deletions, duplications etc.). This is welcome news given the sparse success of SNP screening, although it would be reasonable to assume that SNPs can modify such structural variants (here for the most recent schizophrenia SNP association study). The pair of papers found similar sites, which is pretty amazing given that many structural variants are rare (see the 2006 survey report). The Copy Number Variation Project provides more details on this important class of variation.
