Abstract excerpt

PURPOSE: This study examined the association between dopaminergic genetic variants and environmental factors in young children with disordered eating and their parents. METHODS: Single nucleotide polymorphisms of DRD2 (rs1800497) and COMT (rs4680) were analyzed in 57 undereating, 51 overeating, and 44 control children, and in their parents. The quality of mother-child interactions during feeding was evaluated by...
