To the Editor: Protein C is a naturally occurring vitamin K—dependent zymogen, which in its activated form is a potent anticoagulant directed against factors V and VIII.1 Heterozygous protein C deficiency is manifested by recurrent venous thromboembolism at a relatively young age, which is manageable by oral anticoagulant treatment.2,3 The homozygous state presents in the neonatal period as overwhelming venous thrombosis4 or purpura fulminans,5 6 7 8 with a high mortality rate.

The mother was a 34-year-old woman who had lost two.
