Abbreviations: OR (95% CI), odds ratio of TDT with 95% confidence interval; PD, panic disorder; p(EMP), pointwise empirical p-value after 1 million permutations; p(TDT), p-value of TDT; SNP, single-nucleotide polymorphism.

Position, location at the UCSC genome browser (hg19, build GRCHr37). Results are shown for SNPs with p(TDT) <0.01. The SNPs rs2912586 and rs2017247 show an r²=1.0, as rs8029900 and rs12914251.
