Recurrent spontaneous intracerebral hemorrhage in a congenitally afibrinogenemic patient: diagnostic pitfalls and therapeutic options. (1/127)

BACKGROUND: Coagulation disorders can cause intracerebral bleeding that may be difficult to detect since subsequent aberrant clot formation may mask early detection. This is an important pitfall because, when diagnosed early, bleeding in these patients is treatable. CASE DESCRIPTION: A patient with congenital afibrinogenemia presented with recurrent hemiparesis. Spontaneous intracerebral hemorrhage was diagnosed, despite an initial negative CT scan. Diagnosis, therapy, and complications of therapy are discussed. CONCLUSIONS: Intracerebral hemorrhage must be strongly suspected in any patient with a coagulation disorder presenting with matching clinical symptoms. Therapy must be installed immediately, before additional investigations, and should be continued even when initial neuroimaging is negative.  (+info)

Hypofibrinogenemia associated with a heterozygous missense mutation gamma153Cys to arg (Matsumoto IV): in vitro expression demonstrates defective secretion of the variant fibrinogen. (2/127)

We genetically analyzed a case of hypofibrinogenemia that showed no bleeding or thrombotic tendency. Direct sequencing of a polymerase chain reaction-amplified gamma-chain gene segment showed a novel nucleotide substitution. This heterozygous mutation encodes both Cys (TGT) and Arg (CGT) at residue 153. To examine the basis for the fibrinogen deficiency, we prepared expression vectors containing mutant gamma-chain DNAs encoding gamma153R and gamma153A for in vitro expression in Chinese hamster ovary (CHO) cells. Enzyme-linked immunosorbent assay and immunoblot analysis of the culture media and cell lysates showed that CHO cells transfected with gamma153R or gamma153A synthesized the variant gamma-chain, but did not secrete variant fibrinogen into the culture medium. Metabolic pulse-chase experiments showed that fibrinogen assembly was impaired when either variant gamma-chain was expressed. In cells expressing normal fibrinogen, assem- bly intermediates and intact fibrinogen were seen in cell lysates prepared after short (3 minutes) or long (1 hour) incubation with (35)S-methionine. Neither intermediates nor intact fibrinogen was seen with the variant gamma-chains. These data suggest that gamma-chains have an important early role in fibrinogen assembly. Thus, our results support the model for fibrinogen assembly proposed by Huang et al (J Biol Chem 268:8919, 1993), in which the first step in assembly is the formation of alphagamma or betagamma dimers, or both. This model implies that gammaCys153 has a critical role in the formation of these early assembly intermediates. We concluded that the gamma153Cys-->Arg substitution does not allow fibrinogen assembly and secretion, and this is manifest in vivo as a fibrinogen deficiency. We designated this variant as fibrinogen Matsumoto IV.  (+info)

The 11 kb FGA deletion responsible for congenital afibrinogenaemia is mediated by a short direct repeat in the fibrinogen gene cluster. (3/127)

Congenital afibrinogenaemia is an autosomal recessive disorder characterised by the complete absence of detectable fibrinogen. We previously identified the first known causative mutations for this disorder in a non-consanguineous Swiss family. The four affected male individuals (two brothers and their first two cousins) were shown to have homozygous deletions of approximately 11 kb of the fibrinogen alpha chain (FGA) gene. Haplotype data suggested that the deletions occurred on three distinct ancestral chromosomes, implying that the FGA region of the fibrinogen locus is susceptible to deletion by a common mechanism, but the sequences responsible for the recombination remained to be identified. Here, we report the detailed characterisation of the deletion by nucleotide sequence analysis of all three deletion junctions and comparison with normal sequences. We found that all three deletions were identical to the base-pair and probably resulted from non-homologous (illegitimate) recombination. The centromeric and telomeric deletion junctions featured both a 7 bp direct repeat, AACTTTT, situated in FGA intron 1 and in the FGA-FGB intergenic sequence and a number of inverted repeats which could be involved in the generation of secondary structures. Analysis with closely linked flanking polymorphic markers revealed the existence of at least two haplotypes, further suggesting independent origins of the deletions in this family.  (+info)

Plasminogen deficiency leads to impaired remodeling after a toxic injury to the liver. (4/127)

Cellular proliferation and tissue remodeling are central to the regenerative response after a toxic injury to the liver. To explore the role of plasminogen in hepatic tissue remodeling and regeneration, we used carbon tetrachloride to induce an acute liver injury in plasminogen-deficient (Plg(o)) mice and nontransgenic littermates (Plg(+)). On day 2 after CCl(4), livers of Plg(+) and Plg(o) mice had a similar diseased pale/lacy appearance, followed by restoration of normal appearance in Plg(+) livers by day 7. In contrast, Plg(o) livers remained diseased for as long as 2.5 months, with a diffuse pale/lacy appearance and persistent damage to centrilobular hepatocytes. The persistent centrilobular lesions were not a consequence of impaired proliferative response in Plg(o) mice. Notably, fibrin deposition was a prominent feature in diseased centrilobular areas in Plg(o) livers for at least 30 days after injury. Nonetheless, the genetically superimposed loss of the Aalpha fibrinogen chain (Plg(o)/Fib(o) mice) did not correct the abnormal phenotype. These data show that plasminogen deficiency impedes the clearance of necrotic tissue from a diseased hepatic microenvironment and the subsequent reconstitution of normal liver architecture in a fashion that is unrelated to circulating fibrinogen.  (+info)

Missense mutations in the human beta fibrinogen gene cause congenital afibrinogenemia by impairing fibrinogen secretion. (5/127)

Congenital afibrinogenemia is a rare autosomal recessive disorder characterized by bleeding that varies from mild to severe and by complete absence or extremely low levels of plasma and platelet fibrinogen. Although several mutations in the fibrinogen genes associated with dysfibrinogenemia and hypofibrinogenemia have been described, the genetic defects of congenital afibrinogenemia are largely unknown, except for a recently reported 11-kb deletion of the fibrinogen Aalpha-chain gene. Nevertheless, mutation mechanisms other than the deletion of a fibrinogen gene are likely to exist because patients with afibrinogenemia showing no gross alteration within the fibrinogen cluster have been reported. We tested this hypothesis by studying the affected members of two families, one Italian and one Iranian, who had no evidence of large deletions in the fibrinogen genes. Sequencing of the fibrinogen genes in the 2 probands detected 2 different homozygous missense mutations in exons 7 and 8 of the Bbeta-chain gene, leading to amino acid substitutions Leu353Arg and Gly400Asp, respectively. Transient transfection experiments with plasmids expressing wild-type and mutant fibrinogens demonstrated that the presence of either mutation was sufficient to abolish fibrinogen secretion. These findings demonstrated that missense mutations in the Bbeta fibrinogen gene could cause congenital afibrinogenemia by impairing fibrinogen secretion. (Blood. 2000;95:1336-1341)  (+info)

Hypofibrinogenemia in an individual with 2 coding (gamma82 A-->G and Bbeta235 P-->L) and 2 noncoding mutations. (6/127)

We investigated the molecular basis of hypofibrinogenemia in a man with a normal thrombin clotting time. Protein analysis indicated equal plasma expression of 2 different Bbeta alleles, and DNA sequencing confirmed heterozygosity for a new Bbeta235 P-->L mutation. Protein analysis also revealed a novel gamma(D) chain, present at a ratio of 1:2 relative to the gamma(A) chain. Mass spectrometry indicated a 14 d decrease in the gamma(D)-chain mass, and DNA sequencing showed this was caused by a novel gamma82 A-->G substitution. DNA sequencing established heterozygosity for 2 further mutations: T-->C in intron 4 of the Aalpha gene and A-->C in the 3' noncoding region of the Bbeta gene. Studies on the man's daughter, together with plasma expression levels, discounted both the Aalpha and Bbeta mutations as the cause of the low fibrinogen, suggesting that the gamma82 mutation caused the hypofibrinogenemia. This was supported by analysis of 31 normal controls in whom the Bbeta mutations were found at polymorphic levels, with an allelic frequency of 5% for the Bbeta235 mutation and 42% for the Bbeta 3' untranslated mutation. The gamma82 mutation was, however, unique to the propositus. Residue gamma82 is located in the triple helix that separates the E and D domains, and aberrant packing of the helices may explain the decreased fibrinogen concentration.

Fibrinogen brescia: hepatic endoplasmic reticulum storage and hypofibrinogenemia because of a gamma284 Gly-->Arg mutation. (7/127)

The proposita suffered from liver cirrhosis and biopsy showed type 1 membrane-bound fiberglass inclusions. The hepatic inclusion bodies were weakly periodic acid-Schiff diastase-positive, and on immunoperoxidase staining reacted specifically with anti-fibrinogen antisera. Coagulation investigations revealed low functional and antigenic fibrinogen together with a prolonged thrombin time of 37 seconds (normal, 17 to 22 seconds) suggestive of a hypodysfibrinogenemia. DNA sequencing of all three fibrinogen genes showed a single heterozygous mutation of GGG (Gly)-->CGG (Arg) at codon 284 of the gamma-chain gene. However, examination of purified fibrinogen chains by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, reverse-phase high-performance liquid chromatography, ion-exchange high-performance liquid chromatography, and isoelectric focusing, failed to show any evidence of the mutant gamma(Br) chain in plasma fibrinogen. This finding was substantiated by electrospray ionization mass spectrometry, which showed only a normal gamma (and Bbeta) chain mass, but a large increase in the portion of their disialo isoforms. We speculate that misfolding of the variant protein causes hepatic retention and the subsequent hypofibrinogenemia, and that the functional defect (dysfibrinogenemia) results from hypersialylation of otherwise normal Bbeta and gamma chains consequent to the liver cirrhosis. These conclusions were supported by studies on six other family members with hypofibrinogenemia, and essentially normal clotting times, who were heterozygous for the gamma284 Gly-->Arg mutation.  (+info)

Homozygous truncation of the fibrinogen A alpha chain within the coiled coil causes congenital afibrinogenemia. (8/127)

The molecular basis of a novel congenital afibrinogenemia has been determined. The proposita, the only affected member in a consanguineous Norwegian family, suffers from a moderate to severe bleeding disorder due to the total absence of any detectable fibrinogen. Dot blots of solubilized platelets revealed a small amount of gamma chain but no A alpha or B beta chains, whereas no chains were detected in plasma dot blots. DNA sequencing of the A alpha chain gene revealed a homozygous C-->T transversion 557 nucleotides from the transcription initiation site. This nucleotide change predicts the nonsense mutation A alpha 149 Arg (CGA)-->stop (TGA). Early truncation of the A alpha chain appears to result in defective assembly or secretion of fibrinogen, probably due to the removal of the C-terminal disulfide ring residues that are critically required for the formation of a stable 3-chained half molecule. (Blood. 2000;96:773-775)  (+info)

Congenital afibrinogenemia results from mutations in one of three genes, FGA, FGB, or FGG. Each of these genes provides instructions for making one part (subunit) of a protein called fibrinogen. This protein is important for blood clot formation (coagulation), which is needed to stop excessive bleeding after injury. In response to injury, fibrinogen is converted to fibrin, the main protein in blood clots. Fibrin proteins attach to each other, forming a stable network that makes up the blood clot.. Congenital afibrinogenemia is caused by a complete absence of fibrinogen protein. Most FGA, FGB, and FGG gene mutations that cause this condition result in a premature stop signal in the instructions for making the respective protein. If any protein is made, it is nonfunctional. When any one subunit is missing, the fibrinogen protein is not assembled, which results in the absence of fibrin. Consequently, blood clots do not form in response to injury, leading to the excessive bleeding seen in people ...

Histopathological analyses were previously reported in two ...
SUMMARY Hereditary fibrinogen abnormalities make up two classes of plasma fibrinogen defects: (1) type I, afibrinogenemia or hypofibrinogenemia, in which there are low or absent plasma fibrinogen antigen levels (quantitative fibrinogen deficiencies), and (2) type II, dysfibrinogenemia or hypodysfibrinogenemia, in which there are normal or reduced antigen levels associated with disproportionately low functional activity (qualitative fibrinogen deficiencies). In afibrinogenemia, most mutations of the three encoding genes of fibrinogen chains are null. In some cases, missense or late-truncating nonsense mutations allow synthesis of the corresponding fibrinogen chain, but intracellular fibrinogen assembly and/or secretion is impaired. In certain hypofibrinogenemic cases, the mutant fibrinogen molecules are produced and retained in the rough endoplasmic reticulum of hepatocytes in the form of inclusion bodies, causing endoplasmic reticulum storage disease. Afibrinogenemia is associated with mild to ...

Congenital afibrinogenemia is a rare autosomal recessive disorder characterized by a hemorrhagic diathesis of variable severity. Although more than 100 families with this disorder have been described, genetic defects have been characterized in few cases. An investigation of a young propositus, offspring of a consanguineous marriage, with undetectable levels of functional and quantitative fibrinogen, was conducted. Sequence analysis of the fibrinogen genes showed a homozygous G-to-A mutation at the fifth nucleotide (nt 2395) of the third intervening sequence (IVS) of the g-chain gene. Her first-degree relatives, who had approximately half the normal fibrinogen values and showed concordance between functional and immunologic levels, were heterozygtes. The G-to-A change predicts the disappearance of a donor splice site. After transfection with a construct, containing either the wild-type or the mutated sequence, cells with the mutant construct showed an aberrant messenger RNA (mRNA), consistent with

The protein encoded by this gene is the beta component of fibrinogen, a blood-borne glycoprotein comprised of three pairs of nonidentical polypeptide chains. Following vascular injury, fibrinogen is cleaved by thrombin to form fibrin which is the most abundant component of blood clots. In addition, various cleavage products of fibrinogen and fibrin regulate cell adhesion and spreading, display vasoconstrictor and chemotactic activities, and are mitogens for several cell types. Mutations in this gene lead to several disorders, including afibrinogenemia, dysfibrinogenemia, hypodysfibrinogenemia and thrombotic tendency. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2014 ...

Congenital plasminogen deficiency is a rare autosomal recessive disorder characterized clinically by chronic mucosal pseudomembranous lesions consisting of subepithelial fibrin deposition and inflammation. The most common clinical manifestation is ligneous (wood-like) conjunctivitis, a redness and subsequent formation of pseudomembranes mostly on the palpebral surfaces of the eye that progress to white, yellow-white, or red thick masses with a wood-like consistency that replace the normal mucosa. The lesions may be triggered by local injury and/or infection and often recur after local excision. Pseudomembranous lesions of other mucous membranes often occur in the mouth, nasopharynx, trachea, and female genital tract. Some affected children also have congenital occlusive hydrocephalus. A slightly increased female:male ratio has been observed (1.4:1 to 2:1) (Schuster and Seregard, 2003; Tefs et al., 2006). Type I plasminogen deficiency is characterized by decreased serum plasminogen activity, ...
We describe a patient with inherited plasminogen deficiency who developed extensive cerebral venous thrombosis. Several other conditions that might have contributed to a hypercoagulable state, including mild thrombocytosis, thyrotoxicosis, and a chronic inflammatory lung disorder, were present. We also discuss the evidence linking plasminogen deficiency with a thrombophilic state. The diagnosis of cerebral venous thrombosis in this case was readily established by nuclear magnetic resonance imaging, a technique that is ideally suited for the evaluation and follow-up of patients with this condition. ...
OBJECTIVES: This study was designed to investigate whether single nucleotide polymorphisms (SNPs) and haplotypes of the fibrinogen gene-cluster (fibrinogen chains alpha [FGA], beta [FGB], and gamma [FGG]) could explain the inter- and intraindividual variability of fibrinogen levels in patients with atherosclerosis. We also searched for genetic determinants affecting the responses of fibrinogen genes to proinflammatory stimulation. BACKGROUND: The mechanisms regulating fibrinogen levels are not fully understood, and they are likely to be regulated by complex gene-environment interactions. METHODS: In the AIRGENE study, 895 survivors of myocardial infarction from 5 European cities were followed prospectively for 6 to 8 months, and plasma fibrinogen, interleukin (IL)-6, and C-reactive protein levels were determined monthly. We analyzed 21 SNPs and the corresponding haplotypes in the 3 fibrinogen genes. RESULTS: Eight SNPs in FGA and FGB were significantly associated with fibrinogen levels. Similarly, 2

Bone formation during fracture repair inevitably initiates within or around extravascular deposits of a fibrin-rich matrix. In addition to a central role in hemostasis, fibrin is thought to enhance bone repair by supporting inflammatory and mesenchymal progenitor egress into the zone of injury. However, given that a failure of efficient fibrin clearance can impede normal wound repair, the precise contribution of fibrin to bone fracture repair, whether supportive or detrimental, is unknown. Here, we employed mice with genetically and pharmacologically imposed deficits in the fibrin precursor fibrinogen and fibrin-degrading plasminogen to explore the hypothesis that fibrin is vital to the initiation of fracture repair, but impaired fibrin clearance results in derangements in bone fracture repair. In contrast to our hypothesis, fibrin was entirely dispensable for long-bone fracture repair, as healing fractures in fibrinogen-deficient mice were indistinguishable from those in control animals. ...

Increased plasma fibrinogen levels have been identified as a risk indicator for myocardial infarction, stroke, and thrombosis. Both environmental and genetic factors make an important contribution to plasma fibrinogen levels in humans. In the present study we evaluated, in patients with serum cholesterol levels between 4 and 8 mmol/L, the relation of plasma levels and polymorphisms of fibrinogen with coronary artery disease (CAD), cross-sectionally at baseline and after a 2-year follow-up period in which they received either a placebo or pravastatin. Higher plasma fibrinogen levels (3.9 g/L) were observed at baseline in patients with the -455AA genotype than in patients with the -455GA (3.2 g/L) and -455GG (3.1 g/L) genotypes of the -455G/A fibrinogen β gene polymorphism (P , .05). Plasma levels of fibrinogen were not related to the baseline angiographic variables (mean segment diameter [MSD] and minimum obstruction diameter [MOD]), nor to the quantitative changes in these angiographic ...

On Tuesday August 1 at 8:10 am, 3 motorcycle officers pulled up to my right on SW Clay right before 3rd. One, Bill Balzer, told me to pull over. I came to a complete stop immediately, dismounted and walked my bike to the sidewalk. No traffic ordinance had been violated. During the 15 or so minutes I was stopped Officer Balzer and I conversed about fixed gear bikes (FGBs). The 2 other officers were silent the entire time; hard to say if they were even listening.. Untrue statements made by the officer include but are not limited to: bikes with coaster brakes usually have a second, supplementary brake; the chain on a FGB is more highly tensioned, making it far more likely to break.. The majority of the officers conversation involved relating anecdotal stories about FGBs, including the following:. 1) He had no idea "these bikes" existed until a Critical Mass, when he witnessed a chain come off a FGB. The rider was then unable to stop. He could provide no other details about this bike.. 2) "I dont ...

Acquired hypofibrinogenemia is due either to a decreased rate of fibrinogen production in the liver or to an increased rate of disappearance from the circulating blood. The latter mechanism can be the result of intravascular coagulation or accelerated fibrinolysis. Whereas the development of thrombolytic therapy has introduced a unique tool for investigation of pure fibrinolytic states, it is not possible to induce intravascular coagulation experimentally in man. Progress in the basic understanding of this condition is therefore dependent on careful investigation of human cases of acquired hypofibrinogenemia.. The case reported below is an example of acquired acute hypofibrinogenemia in a ...
Fibrinogen is a plasma protein that has been reported to be associated with an increased risk of atherothrombotic diseases and venous thrombosis. The most common polymorphism that has been studied so far in different populations is the G-455→A polymorphism in the promoter region of the β-fibrinogen gene. We studied 160 healthy unrelated Lebanese individuals for the prevalence of -455G-G, -455G-A and -455A-A genotypes of the β-fibrinogen gene and the frequency of G and A alleles using a reverse hybridization PCR assay. The prevalence of the G-G, G-A, and A-A genotypes were found to be 60.6, 31.9 and 7.5percent, respectively. The frequency of the G and A alleles were found to be 0.77 and 0.23, respectively. As compared to other ethnic groups, the Lebanese individuals were found to have a relatively high prevalence of the A allele which may predispose them to develop cardiovascular diseases as well as thrombotic events. This study provides additional unique genetic information pertaining to the ...
More than 50 mutations in the PLG gene have been identified in people with congenital plasminogen deficiency. This disorder is characterized by hard growths on the mucous membranes, which are the moist tissues that line body openings such as the eyelids and the inside of the mouth. Congenital plasminogen deficiency most often affects the conjunctiva, which are the mucous membranes that protect the white part of the eye (the sclera) and line the eyelids.. PLG gene mutations can decrease the amount of plasminogen produced, its function, or both. When the mutations affect plasminogen levels as well as the activity of the protein, affected individuals may be said to have type I congenital plasminogen deficiency, characterized by the growths previously described. People with PLG gene mutations that result in normal levels of plasminogen with reduced activity are said to have type II congenital plasminogen deficiency or dysplasminogenemia. This form of the condition often has no symptoms.. A reduction ...
A low concentration of thrombin is added to plasma and the rate of reaction for the conversion of fibrinogen to fibrin is measured in seconds. The enzymatic cleavage of fibrin peptides is rate limiting because of the low concentration of thrombin. Prolongation of thrombin time can be caused by heparin, elevated levels of fibrin/fibrinogen degradation products (FDP), hereditary or acquired fibrinogen abnormalities (hypofibrinogenemia or dysfibrinogenemia), or the presence of fibrinolytic agents (e.g., tPA, urokinase ...

OBJECTIVE: We describe two 3-year-old patients with systemic juvenile idiopathic arthritis (SJIA) who developed hepatitis A-associated macrophage activation syndrome (MAS). One patient showed MAS as the presenting manifestation of SJIA, while MAS complicated SJIA during the second year of the disease course in the other child. Both girls presented with fever, jaundice, hepatosplenomegaly, neurological involvement, mucosal hemorrhage, and purpura. Cytopenias, hypofibrinogenemia, and hemophagocytosis confirmed the diagnosis. After aggressive treatment with high-dose corticosteroids and immunosuppressants one patient entered remission while the other one died. Hepatitis A virus may induce severe MAS in SJIA. ...
Kaposiform hemangioendotheliomas (KHE) are extremely rare life threatening tumors which can be associated with Kasabach-Merritt Phenomenon consisting of profound thrombocytopenia and hypofibrinogenemia causing a significant risk of bleeding and an associated mortality rate as high as 20% to 30%. Despite the severity of potential complications, we lack uniform guidelines for the treatment and response to treatment of children and young adults with these tumors. KHE patients have been treated with a multitude of aggressive drug regimens without prospective evaluation of response or safety. Presently, vincristine is considered the standard of practice. We have treated a subset of these patients on study SIR-DA-0901 (FDA Grant# 5RO1FD003712-01). This study is a phase II trial assessing the efficacy and safety of sirolimus for the treatment of complicated vascular anomalies. Although the numbers are small, the response has been extremely promising with excellent tolerability. There is pre-clinical ...

... is an autoimmune disease, in which "antiphospholipid antibodies" (anticardiolipin antibodies and lupus anticoagulant) react against proteins that bind to anionic phospholipids on plasma membranes. Like many autoimmune diseases, it is more common in women than in men. The exact cause is not known, but activation of the system of coagulation is evident. Clinically important antiphospholipid antibodies (those that arise as a result of the autoimmune process) are associated with thrombosis and vascular disease. The syndrome can be divided into primary (no underlying disease state) and secondary (in association with an underlying disease state) forms. Anti-ApoH and a subset of anti-cardiolipin antibodies bind to ApoH, which in turn inhibits Protein C, a glycoprotein with regulatory function upon the common pathway of coagulation (by degradating activated factor V). Lupus anticoagulant (LAC) antibodies bind to prothrombin, thus increasing its cleavage to thrombin, its active ...
Under homeostatic conditions, the body is maintained in a finely tuned balance of coagulation and fibrinolysis. The activation of the coagulation cascade yields thrombin that converts fibrinogen to fibrin; the stable fibrin clot being the final product of hemostasis. The fibrinolytic system then functions to break down fibrinogen and fibrin. Activation of the fibrinolytic system generates plasmin (in the presence of thrombin), which is responsible for the lysis of fibrin clots. The breakdown of fibrinogen and fibrin results in polypeptides called fibrin degradation products (FDPs) or fibrin split products (FSPs). In a state of homeostasis, the presence of plasmin is critical, as it is the central proteolytic enzyme of coagulation and is also necessary for the breakdown of clots, or fibrinolysis.[citation needed] In DIC, the processes of coagulation and fibrinolysis are dysregulated, and the result is widespread clotting with resultant bleeding. Regardless of the triggering event of DIC, once ...
... is inherited as an X-linked recessive trait. It occurs in males and in homozygous females (which is only possible in the daughters of a haemophilic male and a carrier or haemophiliac female[9]). However, mild haemophilia A is known to occur in heterozygous females due to X-inactivation, so it is recommended that levels of factor VIII and IX be measured in all known or potential carriers prior to surgery and in the event of clinically significant bleeding.[4][10] About 5-10% of people with haemophilia A are affected because they make a dysfunctional version of the factor VIII protein, while the remainder are affected because they produce factor VIII in insufficient amounts (quantitative deficiency).[10] Of those who have severe deficiency (defined as ,1% activity of factor VIII), 45-50% have the same mutation, an inversion within the factor VIII gene that results in total elimination of protein production.[10] Since both forms of haemophilia can be caused by a variety of different ...
