title: A 'new' blood group antigen Fra: incidence, inheritance and genetic linkage analysis.
abstract: 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.
