Fanconi anemia (FA) is a rare inherited disorder characterized by congenital abnormalities, progressive bone marrow failure, and a predisposition to malignancies. Detecting FA can be challenging, as it involves identifying increased chromosomal sensitivity to DNA cross-linking agents and detecting causative genetic variants via genome sequencing. We report two cases of siblings with FA, both confirmed to have the FANCD2 variant through whole-exome sequencing (WES).

Article Synopsis
  • β-thalassemia major (β-TM) is a genetic blood disorder that leads to low production of β-globin chains, increasing the risk of complications like thrombosis in patients, especially those getting frequent blood transfusions.
  • * The study involved 118 β-TM patients who had received at least 20 blood transfusions and 120 healthy controls, measuring levels of natural anticoagulants.
  • * Results showed significantly lower levels of protein C and antithrombin in β-TM patients, suggesting that they are at a higher risk for thrombosis due to reduced levels of these anticoagulants.

The prothrombin time (PT) test is commonly used to monitor deficiencies in coagulation factors. A prolonged PT may indicate a deficiency of factors II, V, VII, X, and fibrinogen, or the presence of an inhibitor. However, further tests are required to differentiate between a true factor deficiency and the presence of an inhibitor.

At early ages, recurrent or persistent infections are associated with increased serum C-reactive protein (CRP). Inflammatory mediators release inhibitory cells named myeloid-derived suppressor cell (MDSC) into circulating and tumor tissues. In the present study, we assayed the percentage and count of whole blood CD11b/CD33/HLA-DR MDSCs or myeloid cells at early ages with infectious diseases and increased CRP.

HUS is a leading cause of AKI in infants. Though new classification of HUS is based on underlying disease, it traditionally defines as diarrhea positive (typical) and negative (atypical). We have no figure of the incidence and prevalence of HUS, the underlying disease and the outcome in Iranian patients.

Background: Manganese is a critical trace element that not only has antioxidant properties, but also is essential for various metabolic pathways and neurotransmitters production. However, it can be toxic at high levels, particularly in the central nervous system. Manganese intoxication can be acquired, but an inherited form due to autosomal-recessive mutations in the SLC30A10 gene encoding a Mn transporter protein has also been reported recently.

Isolated extramedullary relapse of chronic myelogenous leukemia (CML) after allogeneic stem cell transplant is rare. There is a case report of a child who developed a granulocytic sarcoma of the maxillary and sphenoid sinuses and lumbosacral spinal cord mass 18 months after allogeneic bone marrow transplant for CML. He was presented with per orbital edema and neurological deficit of lower extremities and a mass lesion was found on spinal cord imaging.

Congenital factor X deficiency is one of the most severe forms of rare bleeding disorders transmitted in autosomal recessive manner. According to the World Federation of Hemophilia survey, 153 patients with factor X deficiency (FXD) live in Iran, but a few studies have been performed to determine the precise distribution of FXD in different parts of the country and to assess molecular basis of this disorder in Iranian patients. This study was conducted to assess the spectrum of factor X gene mutation in Iranian patients with congenital FXD.

Factor XIII (FXIII) deficiency is an extremely rare hemorrhagic disorder with an approximate worldwide incidence of one per two million. With current tests, diagnosis of this disease can be made more precisely. However, factors such as the number of patients with FXIII deficiency (FXIIID), available diagnostic coagulation tests and the number of molecular studies have affected the diagnosis of FXIIID in different parts of the world.

Background: Venous thromboembolism (VTE) could be manifested as deep venous thrombosis (DVT) or pulmonary embolism (PE). DVT is usually the more common manifestation and is usually formation of a thrombus in the deep veins of lower extremities. DVT could occur without known underlying cause (idiopathic thrombosis) which could be a consequence of an inherited underlying risk factor or could be a consequence of provoking events, such as trauma, surgery or acute illness (provoked thrombosis).

Background: Interleukin (IL)-10 is an important anti-inflammatory and immunomodulatory cytokine. Some authors believe that single nucleotide polymorphisms (SNP) in the promoter region of the IL-10 gene have been associated with susceptibility to HIV infection and progression to AIDS, but its role is not clearly defined yet. The present study was undertaken to evaluate the association between HIV infection susceptibility and progression with SNP in the promoter region of the IL-10 gene.

Factor XIII deficiency (FXIIID) is an extremely rare bleeding disorder with the highest global incidence in southeast of Iran. Southwestern Afghanistan (Nimruz Province) is located near the border with Iran in the vicinity of Sistan and Baluchestan Province in southeast Iran, and there seems to be a high prevalence of FXIIID in Nimruz. Thus, this cross-sectional study was designed to assess the prevalence of FXIIID, molecular basis as well as clinical manifestations of FXIIID in Southwestern Afghanistan.

Factor XIII deficiency (FXIIID) is a rare bleeding disorder with an estimated prevalence of 1 in 2-million population worldwide. In Iran, a Middle Eastern country with a high rate of consanguineous marriages, there are approximately 473 patients afflicted with FXIIID. An approximately 12-fold higher prevalence of FXIIID is estimated in Iran in comparison with overall worldwide frequency.

Background: Factor V deficiency (FVD) is a rare bleeding disorder (RBD) mostly present in regions with a high rate of consanguinity. FVD after FXIII deficiency is the next more prevalent RBD in Sistan and Baluchistan (S&B) in southeastern Iran. The aim of this study was to evaluate the clinical manifestations and severity of bleeding diathesis in patients with FVD.

Factor XIII (FXIII) deficiency is a rare hemorrhagic disorder for which the highest incidence occurs in southeast Iran. The aim of this study was to assess molecular characteristics, clinical manifestations and management of life-threatening diathesis in FXIII deficiency. This study was conducted on 190 patients with FXIII deficiency.

Combined deficiency of coagulation factors is considered as an extremely rare bleeding disorder (RBD) inherited in an autosomal recessive pattern. This disorder is more likely to occur in regions with a high rate of consanguineous marriages or in restricted communities. Sistan and Baluchistan, a province in southeast of Iran with a high rate of consanguinity, is a clear model of such regions with a very high prevalence of recessively inherited disorders.

Introduction: FLT3 ITD and D835 mutations occur in high frequency in AML and to a lower rate in ALL patients with poor prognosis.

Methods: ITD and D835 mutations were studied in 100 diagnosed acute leukemia patients including 27 AML and 73 ALL with various FAB classifications by PCR and PCR-RFLP, respectively. Subsequently, PCR products of positive samples were confirmed by sequencing analyses.

Background: Atypical hemolytic uremic syndrome (aHUS), a rare disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, and acute renal failure, is associated with mutations and polymorphisms in various components and regulators of the complement alternative pathway (AP), including factor H, factor I, membrane cofactor protein (MCP or CD46) and factor B. This impaired regulation of the alternative pathway leads to a procoagulant state with microthrombi formation in the renal vasculature, which influences disease onset and progression.

Aim Of The Study: To evaluate the role of complement regulatory factors in occurrence of aHUS; we also included evaluation of ADAMTS13 activity and autoantibody against ADAMTS13 in order to exclude thrombotic thrombocytopenic purpura (TTP) cases, which might have overlapping clinical and laboratory findings.
