Also, in normal cervix, COL17A1 levels do not significantly differ from those in breast carcinoma (p = 0.1417, Mann-Whitney U test; n = 3 and n = 1041, respectively), whereas the levels in normal cervix are significantly lower than in normal breast tissue (p = 0.0027, Mann-Whitney U test; n = 3 and n = 112, respectively; Fig. 5g). Here, COL17A1 is linked to breast carcinoma.
