Objective To investigate the classification, clinical manifestations, laboratory findings, and genetic mutations associated with hereditary fibrinogen disorders in Chinese population. Methods Between February 2015 and February 2022, 65 patients with congenital fibrinogen disorders (CFD) were identified at Wuhan Union Hospital. Comprehensive data were available for 51 patients, allowing for a retrospective analysis.

Congenital dysfibrinogenemia (CDF) is the most common type of congenital fibrinogen disorders, characterized by dysfunctional fibrinogen. Its prevalence is significantly underestimated due to the absence of obvious clinical symptoms in most patients. In addition to bleeding manifestations, patients with CDF may experience thrombotic events or pregnancy-related complications.

Background: Congenital dysfibrinogenemia is characterized by reduced fibrinogen activity, but normal immunoreactive fibrinogen levels. Here, we present a novel case with an elevated risk of thrombosis.
Methods: Coagulation assays, gene analysis, in silico tools, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), fibrin polymerization, thrombin generation assay, and electron microscopy scanning were utilized to elucidate the pathogenic mechanism.

Congenital fibrinogen disorders (CFDs) include afibrinogenemia, hypofibrinogenemia, dysfibrinogenemia, and hypodysfibrinogenemia. The fibrinogen levels, the clinical features, and the genotype define several sub-types, each with specific biological and clinical issues. The diagnosis of CFDs is based on the measurement of activity and antigen fibrinogen levels as well as on the genotype.

Introduction: Congenital hypofibrinogenemia (CH) and congenital dysfibrinogenemia (CD) are rare coagulation disorders caused by quantitative or qualitative defects in the fibrinogen gene. The aim of this study was to characterize the genetic background and the clinical manifestations of congenital fibrinogen disorders in the patients from Slovakia registered at the National Haemophilia Centre.
Materials And Methods: Results of genetic analysis of the fibrinogen genes FGA, FGB and FGG using polymerase chain reaction followed by direct sequencing were evaluated in 36 patients.
