Similarly to its paralog SHKBP1, analyses performed on COSMIC database point out KCTD3 overexpression in other tumor types, such as breast cancer (14.2%; FC = 1.3, p value < 0.001 in the GENT2 db) and stomach (13%; FC = 1.83, p value < 0.001 by GENT2 analysis). This evidence concerns the gene SHKBP1 and neoplasm.
