Fig 1. Manhattan plot of MAGWAS p-values for the drug erlotinib.

Manhattan plot of MAGWAS -log₁₀ (p-value) over 22 autosomes for the association of genotype and cell viability for the drug erlotinib. The dashed and solid lines indicate the thresholds for the genome-wide suggestive significance level of 10⁻⁶ and the genome-wide significance level of 10⁻⁸, respectively. The peak on chromosome 16 has seven SNPs surpassing the genome-wide significance level (the solid horizontal line), including the SNPs rs12447326 and rs1800566.
