Term Description

The presence of the heterozygous missense mutation -1639 G>A in the VKORC1 gene can result in warfarin resistance. VKORC1 DNA analysis is performed by PCR followed by restriction enzyme digestion to detect -1639 G>A.

Part Description

LP65679-0   VKORC1 gene
The VKORC1 gene (vitamin K epoxide reductase complex, subunit 1) [HGNC Gene ID:23663] is located on chromosome 16p11.2. Vitamin K is essential for blood clotting but must be enzymatically activated. This enzymatically activated form of vitamin K is a reduced form required for the carboxylation of glutamic acid residues in some blood-clotting proteins. The product of this gene encodes the enzyme that is responsible for reducing vitamin K 2,3-epoxide to the enzymatically activated form. Fatal bleeding can be caused by vitamin K deficiency and by the vitamin K antagonist warfarin, and it is the product of this gene that is sensitive to warfarin. In humans, mutations in this gene can be associated with deficiencies in vitamin-K-dependent clotting factors and, in humans and rats, with warfarin resistance. Two pseudogenes have been identified on chromosome 1 and the X chromosome. Two alternatively spliced transcripts encoding different isoforms have been described.
