Investigation of the inheritance of a 'new' low-incidence red cell antigen (Fra) indicates that it is an autosomal dominant marker and not part of the ABO, MNSs, P, Rh, Kell, Lutheran, Duffy, Kidd, Dombrock or Scianna blood group systems. No genetic linkage was established between 3Fr, the locus governing production of Fra, and any of 21 other markers.
对一种“新的”低发生率红细胞抗原（Fra）遗传情况的研究表明，它是一种常染色体显性标记，并非ABO、MNSs、P、Rh、Kell、Lutheran、Duffy、Kidd、Dombrock或Scianna血型系统的一部分。控制Fra产生的基因座3Fr与其他21种标记中的任何一种之间均未发现遗传连锁关系。
