Direct regional assignment of the gene for vitamin D binding protein (Gc-globulin) to human chromosome 4q11-q13 and identification of an associated DNA polymorphism

Hum Genet. 1986 Jul;73(3):225-9. doi: 10.1007/BF00401232.


Using a characterized human vitamin D binding protein (DBP) cDNA probe and a panel of rodent X human somatic cell hybrids, we established the chromosomal location of the structural gene for DBP on human chromosome 4. In situ hybridization of 3H-labeled DBP cDNA to human metaphase chromosomes confirmed this assignment and allowed regional localization to bands 4q11-4q13. A restriction fragment length polymorphism associated with the DBP gene that should prove useful in future linkage studies was identified with the enzyme BamHI.
