Bilateral Acute Renal Infarction Secondary to Methylene Tetrahydrofolate Reductase A1298C and PAI-1 Mutation.

We present this rare case of hyperhomocysteinemia due to a mutation in methylene-tetrahydrofolate-reductase (MTFHR) combined with plasminogen activator inhibitor deficiency, causing bilateral renal artery thrombosis. This case highlights the importance of genetic screening in individuals with a family history of thrombotic diseases. There seems to be a role of intervention, even in the setting of renal infarction.
