IKZF1 and type 1 diabetes mellitus: Figure 2B shows that 44 regions contributed eQTLs to the 219 genome-wide trans-scores that were associated with T1D at p<10−9. Of the 32 regions contributing to two or more of these 219 T1D-associated genome-wide scores, ten contained SNPs previously reported as GWAS hits for T1D. Four regions containing T1D-associated SNPs contributed to more than five of these scores: PTPN22 on chromosome 1, BACH2 on chromosome 5, IKZF1 on chromosome 7, and the 12q24 region containing ATXN2.
