Abstract
Genome-wide scans for linkage have provided one of the dominant approaches adopted by researchers in their efforts to identify genes responsible for the inherited component of type 2 diabetes susceptibility. Around 20 genome scans have now been completed, in a wide variety of populations. Integration of data from these diverse scans has proven far from trivial, but the contours of genome-wide linkage topography are steadily emerging from the fog of data. Identification of the calpain- 10 gene as the probable basis for the chromosome 2q linkage seen in Mexican Americans has provided validation of this positional cloning approach. This report provides an update on recent type 2 diabetes genome scan data, focusing on several chromosomal regions where the evidence for linkage has considerably strengthened in the past year. The current and future value of genome-wide linkage information in the search for type 2 diabetes susceptibility effects is also discussed.
