Gazda et al. (2006) determined that the pathways related to apoptosis and cancer had altered in adult DBA patients in remission at the time. O’Brien et al. (2017) studied with relatively younger (transfusion or steroid-dependent) patients with RP and GATA1 mutations, and they demonstrated that peripheral blood-derived CD34 + cells showed altered gene expression profile. Here, CD34 is linked to cancer.
