Summary of array results for OR gene and pseudogene loci and comparison with DGV.

Copy-number variable loci are OR loci with R–measures (median normalized microarray intensity log2-ratio across an OR locus) falling beyond the cutoff C = |0.18| (see Methods). ORs were considered as copy-number variable if a gain or loss was identified in at least one individual. The variability status of each locus was compared to the Database of Genomic Variants (DGV). “New CNV”: CNV identified by us, not in DGV; “Confirmed CNV”: CNV identified by us, present in DGV; “Undetected CNV”: present in DGV, not identified in our panel of individuals; “Confirmed not variable”: was not identified as being copy-number variable by us, and is not reported in DGV.
