Although strokes are more common among African Americans, factor V Leiden is more common in people whose ancestors came from Northern Europe. Between 3% and 8% of people with European ancestry are heterozygous (they inherited a mutation from one parent) for factor V Leiden. About 1 in 5,000 people are homozygous (they have inherited a mutant copy from each parent).
