These include: Arhgap31, Boc, Catspere2, Cd47, Cldn10, Dsp, Fuz, Igsf9, Iqgap2, Npnt, Pcdhgc3, Pphln1, Sprr1a, and Svil. Subsequently, we studied the association in co-occurrence or mutual exclusivity within 994 samples of human breast invasive carcinoma in The Cancer Genome Atlas (TCGA) of the latter list of genes. This evidence concerns the gene SPRR1A and invasive breast carcinoma.
