Because of the association for CH with the CRY1 SNP rs8192440, we grouped the samples by rs8192440 genotype, independent from disease phenotype (Figure 2B), but could not see a correlation between rs8192440 genotype and relative CRY1 gene expression (GG/GA/AA: 0.182 ± 0.503 vs. 0.177 ± 0.284 vs, ˗0.085 ± 0.313, p=0.60). The gene discussed is CRY1; the disease is cyclic hematopoiesis.
