RCCD1 and migraine disorder: These seven putative novel lead SNPs were mapped to the nearest protein-coding genes of MANBA, RCCD1, ROBO1, KDM4A, ADAMTS9, KCNK16, and MYBPC3. Six of these lead SNPs or loci are novel for both migraine and glycemic traits as they were not previously reported to be associated with these traits, with one locus (MANBA) being novel for migraine but not FG.
