Linkage between the loci for mitochondrial malic enzyme (ME2) and coagulation factor XIIIA subunit (F13A)

The locus for the mitochondrial malic enzyme (ME2) seems to be closely linked to the gene coding for the A subunit of coagulation factor XIII (F13A). From 18 informative families with 54 children a maximum lod score of 4.33 was obtained at a recombination fraction of 0.10. Since the assignment of F13A to the short arm of chromosome 6 was recently confirmed, the locus for ME2 can be added to this linkage group. The map order seems to be: GLO1 - HLA - F13A - ME2.
