Chunk #46 — Rare and Common Variants — HTR2B
Text
An HTR2B stop codon was linked to severe impulsive aggression, ASPD, and alcoholism, with an effect that appeared to be modulated by stress, alcohol consumption, and hormones. Unlike the MAOA stop codon, the HTR2B stop codon is recurrent, being found in at least 100,000 individuals, but population-restricted.
