The disease has an autosomal recessive mode of inheritance and therefore occurs with an equal incidence among males and females. Heterozygous mutation carriers usually do not have clinical manifestations. The molecular basis of this disease differs from that of stand-alone congenital deficiencies of FVIII and FV. F5F8D is caused by mutations in either <i>LMAN1</i> or <i>MCFD2</i>, which encode components of a cargo receptor complex for endoplasmic reticulum to Golgi transport of FV and FVIII, leading to defects in an intracellular transport pathway shared by these two coagulation factors. Congenital combined deficiency of FV and FVIII is characterized by decreased activities of both FV and FVIII in plasma, usually to 5 to 30% of normal. Clinical manifestations in most cases are represented by mild or moderate hemorrhagic syndrome. The simultaneous decreases of two coagulation factors present complications in the diagnosis and management of the disease.

In biallelic BSS, giant platelets in the peripheral blood smear, absence of ristocetin-induced platelet aggregation (RIPA) using light transmission aggregometry (LTA), and complete loss of GPIbIX complex in flow cytometry are observed, whereas in monoallelic forms, genetic diagnosis is recommended due to the presence of large platelets in the peripheral blood smear, decreased or normal RIPA response in LTA, and partial loss or normal GPIbIX complex in flow cytometry.

However, the correlation between bleeding severity and coagulation factor activity levels remains inconsistent. This systematic review investigates this relationship to enhance understanding and improve management strategies for patients with RBD. This review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered with the International Prospective Register for Systematic Reviews (PROSPERO) (CRD42024504537). Using the PICO (Population, Intervention, Comparator, and Outcomes) framework, the study focused on RBD patients to explore the correlation between coagulation factor activity levels and bleeding severity. A comprehensive search was conducted across PubMed, Scopus, and Web of Science until April 1, 2024, with data extracted on bleeding severity, phenotype, and coagulation factor activity levels. The analysis highlights complex and often inconsistent relationships between coagulation factor levels and the severity of bleeding. In cases of fibrinogen deficiency, three out of four studies (&lt;i&gt;n&lt;/i&gt; = 73 of 111 cases, 66%) demonstrated a moderate to strong correlation between fibrinogen levels and bleeding severity. In prothrombin deficiency, one of two studies (&lt;i&gt;n&lt;/i&gt; = 16 of 29 cases, 55%) found a strong correlation between FII levels and bleeding severity. Four of six studies (&lt;i&gt;n&lt;/i&gt; = 106 of 139 cases, 76%) in FV deficiency found a weak or no correlation between factor activity and bleeding severity. In combined FV and FVIII deficiency, two of three studies (&lt;i&gt;n&lt;/i&gt; = 26 of 60 cases, 43%) found a significant correlation between factor activity and bleeding severity. In FVII deficiency, four (of nine) studies with a study population of 325 patients (65%) found a weak correlation between factor activity and severity of bleeding. Almost all studies (five of six studies, &lt;i&gt;n&lt;/i&gt; = 114 of 118 patients, 97%) in FX deficiency revealed a strong correlation between FX levels and bleeding severity. In FXI deficiency, most studies (five of seven studies, &lt;i&gt;n&lt;/i&gt; = 254 patients, 93%) found a weak or no correlation between factor activity and bleeding severity or symptoms. For FXIII deficiency, there was a moderate to strong correlation between FXIII activity and bleeding severity in all three studies (&lt;i&gt;n&lt;/i&gt; = 61 patients).

Much less is known about platelet-type VWD (PT-VWD), a rare platelet function defect, and a \"nonidentical\" twin bleeding phenotype to type 2B VWD (2B-VWD). Rather than a defect in the von Willebrand factor (<i>VWF</i>) gene, PT-VWD is caused by a platelet <i>GP1BA</i> mutation leading to a hyperaffinity of the glycoprotein Ibα (GPIbα) platelet surface receptor for VWF, and thus increased platelet clearing and high-molecular-weight VWF multimer elimination. Nine <i>GP1BA gene</i> mutations are known. It is historically believed that this enhanced binding was enabled by the β-switch region of GPIbα adopting an extended β-hairpin form. Recent evidence suggests the pathological conformation that destabilizes the compact triangular form of the R-loop-the GPIbα protein's region for VWF binding. PT-VWD is often misdiagnosed as 2B-VWD, even the though distinction between the two is crucial for proper treatment, as the former requires platelet transfusions, while the latter requires VWF/FVIII concentrate administration. Nevertheless, these PT-VWD treatments remain unsatisfactory, owing to their high cost, low availability, risk of alloimmunity, and the need to carefully balance platelet administration. Antibodies such as 6B4 remain undependable as an alternative therapy due to their questionable efficacy and high costs for this purpose. On the other hand, synthetic peptide therapeutics developed with <i>In-Silico Protein Synthesizer</i> to disrupt the association between GPIbα and VWF show preliminary promise as a therapy based on in vitro experiments. Such peptides could serve as an effective diagnostic technology for discriminating between 2B-VWD and PT-VWD, or potentially all forms of VWD, based on their high specificity.
