Abstract
Inherited thrombophilia is an important cause of venous thrombosis. The Factor V
Leiden (FVL) is the most commonly encountered mutation, followed by the
prothrombin G20210A gene mutation (PTM). The typical venous thrombotic events
(VTEs) associated with PTM mutations are deep vein thrombosis (DVT) and
pulmonary embolisms (PE). The PTM is inherited in an autosomal dominant pattern
with variable penetrance. While heterozygous PTM mutations are more frequent and
well documented in the literature, rare cases of homozygous PTM mutations are
also reported. In this report, we discuss a 56-year-old male with a past medical
history of homozygous prothrombin gene mutation (G20210A) who presented with an
unprovoked DVT of the right lower extremity involving both the proximal and
distal veins associated with multiple bilateral PEs. This case is unique in
terms of the homozygous PTM inheritance, the age at which the patient presented
(usually presentation is earlier in life), and the fact that he had a recurrence
of both DVT and PE simultaneously.
