NALCN and Behcet disease: More specifically, the correlation between NALCN mRNA expression and the SCZ-associated gene GABRB2 in human brain (Kang et al., 2011), along with the association between the Drosophila homolog, na with circadian rhythms (disruptions of which are a hallmark of BD) suggest that NALCN may play a role in these two disorders (reviewed in Lenox et al., 2002).
