title: Pulmonary embolism and premature labor in a patient with both factor V Leiden mutation and methylenetetrahydrofolate reductase gene C677T mutation.
abstract: Multiple risk factors for thrombosis were found in a 21 year old female who experienced three episodes of premature labor and developed severe pulmonary embolism during her third pregnancy. This patient is heterozygous for factor V Leiden mutation and homozygous for methylenetetrahydrofolate reductase (MTHFR) gene nucleotide 677 C to T (C677T) point mutation. This is a first report of the concordance of homozygous MTHFR C677T mutation in an individual with factor V Leiden mutation. This new case provides further evidence that synergism of multiple genetic and acquired risk factors is often encountered in young patients with symptomatic venous thrombosis.
