CXCL10 and cutaneous mastocytosis: Table 1 provides characteristics of all subjects as well as the frequencies of genotypes and alleles in the CXCL10 promoter polymorphisms. There were no differences in age and gender between non-CM and CM patients (Table 1). Anemia was present in all groups, but the hemoglobin levels were significantly lower in the CM patients when compared to non-CM patients (p<0.001, Table 1). Peripheral blood parasitemia was higher among CM patients compared to non-CM patients (p<0.001, Table 1).
