Homozygous protein C deficiency is among rare causes of thrombophilia. Herein, we present a neonate with purpura fulminans, disseminated intravascular coagulation and severe intracranial hemorrhage who was found to have plasma protein C level of 4%. The molecular work-up revealed a novel homozygous mutation of T903C (amino acid position Leu 270 Pro) located in a catalytic domain region of PROC gene. Asymptomatic course in patients with low but measurable levels of protein C levels has been reported, which is different than observed in our patient who had a very severe course despite plasma protein C level of 4%.
