Distribution of olfactory receptor (OR) genes + pseudogenes on chromosome (Chr) 11. Total length of Chr 11 is 134 Mb. The two regions with dense OR genes correspond to OR gene Cluster II (11p, left) and Cluster I (11q, middle). The candidate regions in this study were selected as those with the highest density of OR genes, using the sliding window technique, and do not cover the entire Cluster II and I regions. Embedded within either cluster are possible candidate genes for nonallergic vasomotor rhinitis other than OR genes—such as the gene for C1 esterase inhibitor, an angiotensin II antagonist-like gene, and a purinergic receptor gene.
