Knowledge of homologies between human and mouse chromosomes is essential for understanding chromosomal evolution and the development of experimental models for human disease. We have reported the identification of a conserved linkage group between human 16p13 and the centromeric portion of the mouse 16. Defining the extent of this linkage conservation has significant biomedical implications since that region of mouse genome contains the Scid mutation and the human 16p13 contains genes that are involved in DNA repair and certain types of human leukemia as well as other diseases such as Rubinstein-Taybi Syndrome. Here, this conserved linkage group has been defined and expanded. It now contains 5 genetic loci and spans more than 3 Mb in human and 23 cM in mouse. The 5 loci are PRM1,2 (protamine 1 and 2), NOP3 (a subclone of D16S237), GSPT1 (a gene involved in the regulation of G1 to S phase transition), MYH11 (a human smooth muscle myosin heavy chain gene) and MRP (multi-drug resistant-associated protein gene). Using a panel of human-rodent hybrids that are informative for different portions of human 16, we have established the following order on human 16p: telomere-NOP3-PRM1,2-GSPT1-(MYH11,MRP)-centromere. The genes were assigned to the mouse chromosome 16 by a mouse-Chinese hamster somatic cell hybrid panel informative for mouse chromosomes. Linkage analysis using backcross mice informative for the Scid mutation indicated the following order and genetic distance (in cM) in mouse: centromere-Nop3-11.7-Prm1-1.4-Gspt1-8.2-(Myh11,Mrp)-1.4-Scid-telomere.
