title: Genotyping of feline MHC (FLA) class II DRB by PCR-RFLP method using group-specific primers.
abstract: For genotyping of feline major histocompatibility complex (FLA) class II DRB, the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method using group-specific primers was tried. Sixty-six DRB genes were classified into 8 groups according to differences in the first 5' amino acid sequences. The group-specific primers were designed as forward ones, which were specific for 5' base sequences of genes in each group. Three to 7 appropriate restricted enzymes were selected by computer analysis for RFLP typing of the genes divided into each group. In 6 out of 9 cats, the results of DRB typed by direct sequence method agreed with results of the PCR-RFLP method using group-specific primers. In the other 3 cats, the number of genes amplified by group-specific primers was I or 2 more than those detected by direct sequence method. The direct sequence method in 9 cats identified 5 new FLA-DRB genes. The PCR-RFLP method using group-specific primers could divide 66 genes into 37 genes and 10 subgroups from the RFLP pattern. One to 6 genes in each cat, and a total of 203 genes and subgroups were detected in 68 domestic cats. The genes detected might be biased to the subgroup G1-1a (28.8%), DRB*0501 (10.3%), G1-2a (9.4%) and G6b (7.4%). The PCR-RFLP method using group-specific primers may be useful in typing FLA class II DRB.
