In general, genetic polymorphisms directly related to BED were observed in various genes (ABCA1, BDNF, DRD3, DRD4, FTO, and Taq1A), while other, non-direct relationships were also observed, although shared with other EDs, such as binge eating episodes (CLOCK, GLUT2, FABP2, HTR2A, MC4R, TAST1R2, and TAST1R3). Here, ABCA1 is linked to X-linked cone dysfunction syndrome with myopia.
