Genetic mapping of five human chromosome 4 orthologues to bovine chromosomes 6 and 17.
Five loci that map to human chromosome 4 (HSA4) were selected to expand the bovine comparative linkage map. Loci included b-casein (CSN2), basic fibroblast growth factor (FGF2), immunoglobulin J chain (IGJ), interleukin 2 (IL2) and microsomal triglyceride transfer protein (MTTP). Polymorphisms for each locus were identified by either polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) or single-strand conformational polymorphism (SSCP) analysis. The bovine genes for CSN2, IGJ and MTTP were mapped by linkage analysis to chromosome 6; FGF2 and IL2 mapped to chromosome 17. These data refine a position of chromosomal evolution to a small region between FGF2 and the previously mapped complement I factor (IF).
