Distribution of the 5-HT1A receptor G(-1019) gene polymorphism in suicide completers and normal controls from the Quebec cohort

Genotypes Alleles
Subjects N C/C C/G G/G C G
Controls 116 85 26 5 196 36
Suicide 102 55 30 17 140 64

  • Control subjects versus suicide cases: genotype, X2 = 12.41, df = 2, p = 0.002; allele, p = 0.00008. Presence of any C allele versus absence of any C allele, p = 0.003. Presence of any G allele versus absence of any G allele, p = 0.0045.
