The ratio of the contacts targeting the perisomatic region (i.e. on Kv2.1-labeled soma and proximal dendrites) was variable (CCKBCs: 48.6 ± 3.1%, range: 16.5–81.1%; PVBCs: 51.6 ± 3.5%, range: 17.4–84.9%) and formed a continuous distribution for both BC types (Figure 8E). The gene discussed is KCNB1; the disease is breast cancer.
