Co-Inherited PROC Variant and Its Effect on Bleeding Severity in Hemophilia A – JTH
Journal of Thrombosis and Haemostasis (JTH) shared on LinkedIn about a recent article by Radha Ramanan et al, adding:
”Prothrombotic PROC Variant Rebalancing Hemostasis in Severe Hemophilia A with Attenuated Bleeding Risk
This study characterizes a heterozygous PROC variant (p.Trp414Arg) causing partial protein C deficiency in a severe hemophilia A patient, demonstrating that this co-inherited prothrombotic modifier enhances thrombin generation and naturally rebalances hemostasis – resulting in a discordantly mild bleeding phenotype.”
