Figure 4. A Heat Map of Log R ratios indicating the quantitative assessments of genotyping examined in a panel of 344 individuals (represented 8) used to determine copy number for the OR region with inferred functional copy number for some of the members under study can be seen here.

Figure 4

Each row represents human individuals and each column of the grid summarizes genotype data for the 15q11.2 OR gene cluster comprising of genes OR4M2, OR4N4 and OR4N3P. The slanting lines above the heat emission signal indicate the copy number markers, which have picked the variation. Three Tibetan (GSH540612, GSM540625, GSM540628) samples showing 15q11.2 OR gene cluster deletion and five HapMap (NA07357, NA12717, NA12891, NA18526, NA18537) samples showing both deletions and duplications in the same region.
