Abstract

Cellular cholesterol metabolism is regulated primarily through the coordinate expression of two proteins, the low density lipoprotein (LDL) receptor and 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase (EC 1.1.1.34). We have used cDNA probes for the human genes encoding these proteins to determine the precise chromosomal location of the two loci. By in situ hybridization we have regionally mapped the LDL receptor gene, LDLR, to the short arm of chromosome 19 in bands p13.1-p13.3. This result concurs with and extends a previous study in which LDLR was mapped to chromosome 19 by screening somatic cell hybrids with a species-specific monoclonal antibody. We have assigned the HMG-CoA reductase gene, HMGCR, to chromosome 5 by Southern blotting of DNA from a somatic cell hybrid panel and to bands 5q13.3-q14 by in situ hybridizations of the cDNA probe to human metaphase cells with normal and rearranged chromosomes.
