Regional conditional association plot of the new genome-wide significant HSCR variant. a Association results at RET locus before the conditional analysis. b Association results when conditioning on the RET lead SNP (rs2505994). Color-coded linkage disequilibrium is shown for the top conditional associated SNP rs144432435—in purple). The x-axis represents the chromosome 10 region (hg19 assembly) surrounding the new hit, while the y-axis represents the strength of the association in −log10 (P value) (see color fig online)
