While no heterogeneities (for breast cancer: I2 = 0.0%, Pheterogeneity = 0.958; and for colorectal cancer: I2 = 36.9%, Pheterogeneity = 0.205, respectively) were found when we analyzed the association between HOXB13 p.Gly84Glu mutation and the risk of the other two kinds of cancers mentioned above. This evidence concerns the gene HOXB13 and colorectal cancer.
