“…To date, the most frequently assessed genetic variations within the 5‐HT systems related to obesity are located at the SLC6A4 gene, although findings are not consistent. 8 , 9 , 10 , 11 , 12 , 13 , 14 Variations in SLC6A4 have also been linked with obesogenic eating behaviors, such as appetite, energy intake, disinhibited eating, and emotional eating. 9 , 15 , 16 , 17 In addition to SLC6A4 , several 5‐HT receptor genes and TPHs, including HTR1B , 18 , 19 HTR2A , 20 , 21 , 22 , 23 HTR2B , 24 HTR2C , 11 , 18 , 20 , 25 , 26 , 27 HTR6 , 28 HTR7 , 19 TPH1 , and TPH2 24 , 29 have also been assessed for potential associations with body weight measures and/or eating behaviors.…”
