    <p>Carriers of the <i>CACNA1C</i> SNP rs1006737 risk allele A have significantly increased activity in the left amygdala in the total sample (x = −24, y = −2, z = −14; FWE P = 0.026) and BD subgroup (x = −24, y = 0, z = −14; FWE P = 0.041), and non-significantly increased activity in the right amygdala in the total sample (x = 26, y = 0, z = −16) and BD subgroup (x = 22, y = 0, z = −20) compared with GG homozygotes during a negative faces paradigm. Abbreviations: BD, bipolar disorder; FWE, family-wise error.
