Likewise, a cross-sectional study [64] of 303 patients with eating disorders (199 with AN, 74 with BN, and 30 with BED) found that BN patients who carried the Val-allele of COMT gene had more severe psychopathology compared to BN patients who carried the Met allele, although no such association was found for the BED patients. Here, COMT is linked to eating disorder.
