SummaryTwo novel polymorphisms were identified in the factor V gene by direct sequencing of intronic areas. One of them, located in intron 9, is the marker closest to the Leiden mutation ever described, whereas the other, in intron 16, displays a rare allele invariantly associated to the mutation. Allele-specific amplification protocols were designed to perform extensive screenings for both polymorphic sites. The new markers were used in combination with six previously described polymorphisms to define specific factor V gene haplotypes. Haplotype investigations in 506Q homozygous thrombotic patients and normal controls showed the presence of a single haplotype underlying the factor V Leiden mutation in Mediterranean populations (among which Greek Cypriots, where the R506Q mutation is particularly frequent) and Indians. When traced in the absence of the Leiden mutation, the background haplotype was found to be present and roughly as frequent as the mutation itself in these populations. These findings indicate a single mutational event, that probably occurred outside Europe, as the cause of the Leiden mutation and provide a powerful tool to investigate its evolutionary history.
