Abstract
Genetic linkage between the HL-A and Bf loci could be confirmed in 43 families with 168 offspring. In 4 families, 5 recombinants out of 82 informative meiotic divisions were observed (r = 6.1%). The localisation of the Bf marker system was studied in 3 families with crossovers between HL-A and MLC. From these data the following map order of human chromosome 6 can be proposed: HL-A (1st locus) -- HL-A (2nd locus)--MLC-Bf---PGM(3). The fact that important components of the classical and alternate pathway of complement activation are governed by genes closely linked with HL-A and MLC loci leads to the proposition to include the Bf system into the Major Histocompatibility Complex in man.
