For validation, the feature and spatial feature plots of MAF, CD248, GJA1, LAMA3, TJP1, LAMC2, and COL17A1 demonstrated to show the location in BRCA samples, and they were highly-expressed in the invasive ductal carcinoma tissue (cluster 2, 4, 7, 9, 12) (Figures 9B, C). Here, GJA1 is linked to invasive ductal breast carcinoma.
