We listed five CNS-related phenotypes in BXD RI strains, including brain to body weight ratio (Figure 3A), novel open field behavior (Figure 3B), anxiety assay (Figure 3C), acoustic startle response (Figure 3D), learning and memory (Figure 3E), as well as fecal corticosterone concentration (Figure 3F) significantly correlated (p < 0.05) with the expression of Ccr6. These correlated phenotypes can be found on the GeneNetwork website with the access numbers of 17494, 11530, 12365, 13355, 20585, and 20113, respectively. The gene discussed is CCR6; the disease is Anxiety.
