[Application of gene technology in the diagnosis of familial hypercholesterolemia].
Familial hypercholesterolaemia is an autosomal dominant disorder characterized by hypercholesterolaemia, xanthomas and premature coronary heart disease. Treatment of hypercholesterolemia is effective and consists of dietary changes and lipid lowering drugs. Only a minor proportion of familial hypercholesterolaemia patients are adequately treated, however. One explanation for this is assumed to be the relatively vague clinical diagnostic criteria applied. Because familial hypercholesterolaemia is caused by a mutation in the gene encoding the low density lipoprotein (LDL) receptor, mutation analysis of this gene could form the basis for specific diagnosis. 29 different mutations in the LDL receptor gene have been found to cause familial hypercholesterolaemia among Norwegian patients, and a total of 681 patients from 322 unrelated families have been provided with a molecular genetic diagnosis. We conclude that the use of molecular genetic analysis is feasible, and should be used clinically.
