Of particular interest is the significant (p<0.05) but modest elevation of AEA in subjects with the FAAH 385 mutant A alleles (Figure 1), since AEA activates the CB1 receptor and has the potential to stimulate appetite and feeding behavior as well as modulate several metabolic functions including fatty acid metabolism and contributes to diet-induced obesity [12], [16]. Here, FAAH is linked to obesity disorder.
