Teneurins 2 and 4 have been linked to tumor differentiation and patient survival in ovarian cancer (Graumann et al., 2017) and Teneurin 3 is expressed at low to moderate levels in a subset of breast cancer patients (e.g., 4 of 12 reported in the Protein Atlas database, https://www.proteinatlas.org/ENSG00000218336-TENM3/pathology). The gene discussed is TENM3; the disease is ovarian carcinoma.
