Abstract：
Since publication of the original Immunohematology review of the Kidd blood group system in 2015 (Hamilton JR. Kidd blood group system: a review. Immunohematology 2015;31:29-34), knowledge has mushroomed pertaining to gene structure, alleles causing variant and null phenotypes, clinical significance in renal transplant and hemolytic disease of the fetus and newborn, and physiologic functions of urea transporters in non-renal tissues. This review will detail much of this new information.
摘要：
自2015年Kidd血型系统的原始免疫血液学综述发表以来（HamiltonJR。肾脏血型系统：综述。免疫血液学2015；31：29-34），关于基因结构的知识如雨后春笋般涌现，等位基因导致变异和无效表型，在肾脏移植和胎儿和新生儿溶血疾病的临床意义，和非肾组织中尿素转运蛋白的生理功能。这篇评论将详细介绍这些新信息。
