[PMID 24286185] In this 2013 article titled "Translational evidence for the involvement of the endocannabinoid system in stress-related psychiatric illnesses", six previous studies of rs1049353 were reviewed. They concluded that the minor A allele may provide protection against depression in response to stress. The gene variants also affected response to antidepressant medication. One study they cited showed that in females, the A allele may confer greater antidepressant responsiveness, but another study showed that in a population of males, the result was opposite and the G allele associated with greater antidepressant responsiveness.
