Subdivisions of the HLA-B5 and Bw35 complex

Population studies in 579 individuals, previously phenotyped to be B5 or Bw35, were carried out with 23 HLA antisera defining the B5-Bw35 complex. The inheritance of five subdivisions in this complex, B5.1, B5.2, B5.y, Bw35 and BHR were tested in 23 families. Differing frequencies of these specificities were observed in American Indians, Blacks, Caucasians, Chinese, Filipinos, Japanese and Mexican Americans.
