There were three new blood group systems including the KANNO blood group system, the Sid blood group system and the CTL2 blood group system (provisional status), have been registered by the International Society of Blood Transfusion (ISBT) registered Science August 2019. The main reason for this update is that the significant SNPs of the KANNO blood group system (rs1800014) and the Sid blood group system (rs7224888) have been found through genome-wide association studies and whole exome sequencing. The new genetic evidences are consistent with the current immunological findings. In addition, although CTL2 antigen has been found on erythrocyte ghost (erythrocyte membrane) since 2017, CTL2 blood group system is still in provisional status due to lack of serological and genetic evidence. In this review, the experimental research advances of these three ISBT blood group systems and discuss the clinical value of the relevant researches was summarized briefly.
