NCAN and Behcet disease: The relevant conclusions and perspective of the study were as follows: (i) NCAN is a potential BD susceptibility factor; (ii) localization of NCAN at the level of central nervous system (cortex, hippocampus), NCAN alleles, and BD susceptibility are positively correlated; and (iii) NCAN-deficient mice should be furthermore studied in order to identify the more subtle changes in the cognitive processes that are severely affected in BD, like learning and memories.
