The rat beige (bg) autosomal recessive gene, causing Chediak-Higashi Syndrome (CHS) in rat, was mapped on Chr 17 by using synteny of rat to mouse and humans. The linkage between the beige gene and PCR-amplified microsatellite markers in (DA-bg × BN)F 1 × DA-bg backcross progeny was analysed. The recombination frequency was 9.5% between Prl and Acrm and 19.1% between Acrm and bg. The proposed order of three genes is Prl-Acrm-bg. This rat bg gene was confirmed to be homologus to the beige (bg) gene of mouse located on Chr 13 and the CHS (Lyst) gene of man located on Chr 1 (1q43).
