Factor XIII and Fibrin Clot Properties in Acute Venous Thromboembolism
International Journal of Molecular Sciences Review Factor XIII and Fibrin Clot Properties in Acute Venous Thromboembolism Michał Z ˛abczyk 1,2 , Joanna Natorska 1,2 and Anetta Undas 1,2,* 1 John Paul II Hospital, 31-202 Kraków, Poland; [email protected] (M.Z.); [email protected] (J.N.) 2 Institute of Cardiology, Jagiellonian University Medical College, 31-202 Kraków, Poland * Correspondence: [email protected]; Tel.: +48-12-614-30-04; Fax: +48-12-614-21-20 Abstract: Coagulation factor XIII (FXIII) is converted by thrombin into its active form, FXIIIa, which crosslinks fibrin fibers, rendering clots more stable and resistant to degradation. FXIII affects fibrin clot structure and function leading to a more prothrombotic phenotype with denser networks, characterizing patients at risk of venous thromboembolism (VTE). Mechanisms regulating FXIII activation and its impact on fibrin structure in patients with acute VTE encompassing pulmonary embolism (PE) or deep vein thrombosis (DVT) are poorly elucidated. Reduced circulating FXIII levels in acute PE were reported over 20 years ago. Similar observations indicating decreased FXIII plasma activity and antigen levels have been made in acute PE and DVT with their subsequent increase after several weeks since the index event. Plasma fibrin clot proteome analysis confirms that clot-bound FXIII amounts associated with plasma FXIII activity are decreased in acute VTE. Reduced FXIII activity has been associated with impaired clot permeability and hypofibrinolysis in acute PE. The current review presents available studies on the role of FXIII in the modulation of fibrin clot properties during acute PE or DVT and following these events. -
Factor XIII Deficiency
Factor XIII deficiency Information for families Great Ormond Street Hospital for Children NHS Foundation Trust 2 Factor XIII deficiency is a type of clotting disorder. A specific protein is missing from the blood so that injured blood vessels cannot heal in the usual way.

Autosomal Recessive Inherited Bleeding Disorders in Pakistan
Naz et al. Orphanet Journal of Rare Diseases (2017) 12:66 DOI 10.1186/s13023-017-0620-6 RESEARCH Open Access Autosomal recessive inherited bleeding disorders in Pakistan: a cross-sectional study from selected regions Arshi Naz1* , Muhammad Younus Jamal1, Samina Amanat2, Ikram Din ujjan3, Akber Najmuddin4, Humayun Patel1, Fazle Raziq5, Nisar Ahmed6, Ayisha Imran7 and Tahir Sultan Shamsi1 Abstract Background: Autosomal recessive bleeding disorders (ARBDs) include deficiencies of clotting factors I, II, V, VII, X, XI, XIII, vitamin K dependent clotting factors, combined factor V & VIII, Von Willebrand Disease (vWD) type 3, Glanzmann’s thrombasthenia (GT) and Bernard–Soulier syndrome. Patients with primary bleeding disorders from all the major provincial capitals of Pakistan were screened for ARBDs. Prothrombin (PT), activated partial thromboplastin time (APTT), bleeding time (BT) and fibrinogen levels were measured. Cases with isolated prolonged APTT were tested for factors VIII and IX using factor assays This was followed by FXI:C level assessment in cases with normal FVIII and FIX levels. vWD was screened in patients with low FVIII levels. Factors II, V and X were tested in patients with simultaneous prolongation of PT and APTT. Peripheral blood film examination and platelet aggregation studies were performed to assess platelet disorders. Urea clot solubility testing was done to detect Factor XIII levels where platelet function tests were normal. Descriptive analysis was done using SPSS version 16. Results: Of the 429 suspected bleeding disorder patients, 148 (35%) were diagnosed with hemophilia A and 211 (49.1%) patients had ARBDs. 70 patients (16.3%) remained undiagnosed. Out of 211 patients with ARBD; 95 (33.8%) had vWD type 3. -

Characterization of a Novel Large Deletion Caused by Double-Stranded Breaks in 6-Bp Microhomologous Sequences of Intron 11 and 12 of the F13A1 Gene
OPEN Citation: Human Genome Variation (2016) 3, 15059; doi:10.1038/hgv.2015.59 Official journal of the Japan Society of Human Genetics 2054-345X/16 www.nature.com/hgv ARTICLE Characterization of a novel large deletion caused by double-stranded breaks in 6-bp microhomologous sequences of intron 11 and 12 of the F13A1 gene Anne Thomas1,3, Vytautas Ivaškevičius1,3, Christophe Zawadzki2, Jenny Goudemand2, Arijit Biswas1,3 and Johannes Oldenburg1 Coagulation Factor XIII is a heterotetrameric protransglutaminase which stabilizes preformed fibrin clots by covalent crosslinking them. Inherited homozygous or compound heterozygous deficiency of coagulation Factor XIII (FXIII) is a rare severe bleeding disorder affecting 1 in 2 million individuals. Most of the patients with inherited FXIII deficiency described in the literature carry F13A1 gene point mutations (missense, nonsense and splice site defects), whereas large deletions (40.5 kb in size) are underrepresented. In this article we report for the first time the complete characterization of a novel homozygous F13A1 large deletion covering the entire exon 12 in a young patient with a severe FXIII-deficient phenotype from France. Using primer walking on genomic DNA we have identified the deletion breakpoints in the region between g.6.143,016–g.6.148,901 caused by small 6-bp microhomologies at the 5´ and 3´ breakpoints. Parents of the patient were heterozygous carriers. Identification of this large deletion offers the possibility of prenatal diagnosis for the mother in this family who is heterozygous for this deletion.

Human Social Genomics in the Multi-Ethnic Study of Atherosclerosis
Getting “Under the Skin”: Human Social Genomics in the Multi-Ethnic Study of Atherosclerosis by Kristen Monét Brown A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Epidemiological Science) in the University of Michigan 2017 Doctoral Committee: Professor Ana V. Diez-Roux, Co-Chair, Drexel University Professor Sharon R. Kardia, Co-Chair Professor Bhramar Mukherjee Assistant Professor Belinda Needham Assistant Professor Jennifer A. Smith © Kristen Monét Brown, 2017 [email protected] ORCID iD: 0000-0002-9955-0568 Dedication I dedicate this dissertation to my grandmother, Gertrude Delores Hampton. Nanny, no one wanted to see me become “Dr. Brown” more than you. I know that you are standing over the bannister of heaven smiling and beaming with pride. I love you more than my words could ever fully express. ii Acknowledgements First, I give honor to God, who is the head of my life. Truly, without Him, none of this would be possible. Countless times throughout this doctoral journey I have relied my favorite scripture, “And we know that all things work together for good, to them that love God, to them who are called according to His purpose (Romans 8:28).” Secondly, I acknowledge my parents, James and Marilyn Brown. From an early age, you two instilled in me the value of education and have been my biggest cheerleaders throughout my entire life. I thank you for your unconditional love, encouragement, sacrifices, and support. I would not be here today without you. I truly thank God that out of the all of the people in the world that He could have chosen to be my parents, that He chose the two of you.
