Overview

Genetic analysis shows mutations in fibrinogen gene increase bleeding risk, indicating a need for careful monitoring.

Key Points

  • To investigate the pathogenesis of congenital hypofibrinogenemia and the associated bleeding risk due to gene mutations.
  • Performed coagulation screening and genetic analysis on a proband with congenital hypofibrinogenemia.
  • Conducted sodium dodecyl sulfate polyacrylamide gel electrophoresis to analyze fibrinogen.
  • Utilized electron microscopy and thromboelastography to study fibrin fibers and coagulation dynamics.
  • Fibrinogen levels measured at 0.81 g/L, 0.95 g/L, and 0.87 g/L by different assays.
  • Identified specific mutations in FGA, FGB, and FGG genes contributing to congenital hypofibrinogenemia.
  • Scanned electron microscopy revealed that fibrin fibers were fine with increased pore sizes.
