In the present study , the clonal relationship was investigated between peripheral blood polymorphonuclear cells ( PMNCs ) and marrow progenitor cells and the origin of ringed sideroblasts in patients with refractory anemia with ring sideroblasts ( RARS ) by polymerase chain reaction ( PCR ) of HUMARA gene .
