Through blood parameters analysis, we found that the number of red blood cells (RBCs) and the mean corpuscular hemoglobin concentration (MCHC) decreased slightly in KITD17/+ mice, with hematocrit (HCT) decreasing significantly (Table S3 and Figure S4), implying the possibility of mild anemia, which is similar to the results found in a mouse model with a KIT loss of function mutation (Ruan et al., 2005). The gene discussed is KIT; the disease is anemia.
