Summary
A new method using filter paper blood samples enables efficient large-scale screening for factor V Leiden mutation. This study found a significantly higher prevalence in a north-eastern German population compared to other European groups.
Area of Science:
- Genetics
- Epidemiology
- Molecular Biology
Background:
- Factor V Leiden mutation prevalence varies across European populations.
- Accurate epidemiological data requires large-scale, reliable screening methods.
- Previous studies lacked sufficient sample sizes for statistical comparison.
Purpose of the Study:
- To develop a cost-efficient method for large-scale factor V Leiden mutation screening.
- To determine the allele frequency in a north-eastern German population.
- To compare prevalence with other European populations.
Main Methods:
- Development of a screening method using capillary blood on filter paper cards.
- Detection of factor V Leiden mutation via heteroduplex analysis.
- Screening of 1,628 alleles from a north-eastern German cohort.
Main Results:
- An allele frequency of 3.56% (7.12% carrier rate) was identified in the German population.
- This prevalence is significantly higher than reported for Italy and the Netherlands.
- Statistical comparison with other populations was limited by small sample sizes in prior studies.
Conclusions:
- The developed filter paper method is effective for large-scale factor V Leiden screening.
- The north-eastern German population exhibits a high prevalence of factor V Leiden mutation.
- Further research with larger sample sizes is needed to confirm inter-population differences.
