Summary In situ hybridization of tritiated cDNA probes for the gene for the B subunit of coagulation factor XIII localized the F13B locus to bands q31–q32.1 on human chromosome 1 and perhaps more precisely to sub-bands 1q31.2 or 1q31.3. Restriction fragment length polymorphisms (RFLPs) were detected with BglII, EcoRI and XbaI. Because the RFLPs detected with each of the three enzymes were concordant in every individual studied and since each showed a similar size difference, it was concluded that the RFLPs probably result from an insertion or deletion of length approximately 0.37–0.4 kb.
