While the previous meta‐analysis by Figlioli et al in 2013 had failed to identify significant risk association with any of these four RET SNPs,6 in our expanded meta‐analysis cohort, we could identify significant risk association of RET L769L and S836S in hereditary MTC and of G691S and S904S in sporadic MTC. This evidence concerns the gene RET and medullary thyroid gland carcinoma.
