Methods and Compositions for the Treatment and Diagnosis of Breast Cancer

A method of detecting breast cancer in a subject comprising a) obtaining a sample from a subject b) contacting the sample obtained from the subject with one or more agents that detect expression of one or more of the markers encoded for by genes chosen from C1orf64, LOC338579, LOC648879, HIST1H4H, ASCL1, COL10A1, MMP11, DSCR6, CYP4Z1, HIST2H4B, BX116033, C6orf126, CLEC3A, HIST2H4A, SERHL2, FLJ23152, ABCC11, ANKRD30A, CNTD2, COL11A1, DHRS2, HIST1H3F, HIST1H3H, HIST2H2AB, KCNK15, LOC441376, LOC643637, LOC646360, PTPRT, RUNDC3A, SCGB2A2, SLITRK6, SYP, UBE2C, ZNF552, LOC388743, POTEC, FSIP1, GFRA1, LOC647333, POTEF, POTEE, POTEK, C2orf27A, LOC727941 (XR—037440.1), NBPF22P, POTEG, RET, TMEM145, LOC727941 (XR—037165.1), NAT1, NXPH1, SERHL2, SYCP2, D59687, CYP4Z1, LOC730024, NOS1AP, UGT2B28, GRM4, FLJ30428, LOC440905, LOC642460, MTL5, GRPR, COL10A1, or a complement thereof;

• c) contacting a non-cancerous cell, e.g. a non-cancerous cell from breast tissue, with the one or more agents from b);
