Japanese researchers studied five cancer related SNPs [rs966513 (9q22.33, FOXE1), rs944289 (14q13.3, PTCSC3), rs2439302 (8p12, NRG1), rs1867277 (9q22.23, FOXE1), and rs6983267 (8q24, POU5F1B)] in a cohort of 959 cases with follicular adenoma (FA), 535 cases with PTC, and 2766 controls. This evidence concerns the gene FOXE1 and Friedreich ataxia.
