Familial hypercholesterolemia (FH) is caused by different mutations in the gene encoding the low density lipoprotein receptor (LDLR). In Caucasian patients, at least three single point mutations have been identified causing FH. The asparagine206 to glutamine, and valine408 to methionine mutations were originally described in Afrikaners and recently identified in Dutch FH patients. The proline664 to leucine mutations was previously identified in an FH homozygote of Asian Indian origin and later identified in patients from London. Any of these mutations can be identified using direct amplification of genomic DNA by the polymerase chain reaction (PCR) and restriction enzyme digestion of PCR products. In this study, 100 unrelated German FH patients were screened for these three mutations. The valine408 to methionine mutation was identified in one individual and subsequently in the hypercholesterolemic child of the proband. Haplotype analysis with 7 restriction fragment length polymorphisms (RFLPs) revealed that the mutant allele carried the same haplotype as the previously described patients in South Africa and the Netherlands. Our finding supports the previous assumption of the European origin of the mutation.
