Abstract
A misdiagnosis of β-thalassemia carrier in samples with Hb Tak and HbD-Punjab, the β-variants, can be a cause of inappropriate genetic counseling thus having a new case of β-thalassemia major. A capillary electrophoresis (CE) is very efficient in separating and quantifying HbA2. In this study, HbA2 levels of samples which were doubted for compound heterozygous Hb Tak/β-thalassemia or heterozygous HbD-Punjab/β-thalassemia were measured and compared between CE and high performance liquid chromatography (HPLC). The molecular confirmation for Hb Tak, HbD-Punjab and β-thalassemia codons 17 (A > T), 41/42 (-TCTT), 71/72 (+A) and IVSI-nt1 (G > T) mutations and 3.4 kb deletion were also performed. Based on DNA analysis, 3 cases were diagnosed as compound heterozygous Hb Tak/β-thalassemia and one for HbD-Punjab/β-thalassemia. The elevated HbA2 levels were found in all 4 samples with rages of 4.6-7.3% on CE while those were not found on HPLC. Thus, the elevated HbA2 measured by CE can be used as a screening parameter for differentiating the homozygote of Hb Tak and HbD-Punjab from the compound heterozygote of these hemoglobinopathies and β-thalassemia.

Abstract
The β-thalassemias are inherited blood disorders that result from insufficient production of the β-chain of hemoglobin. More than 200 different mutations have been identified. β-Thalassemia major requires life-long transfusions. The only cure for severe β-thalassemia is to provide patients with hematopoietic stem cells. Globin gene therapy promises a curative autologous stem cell transplantation without the immunologic complications of allogeneic transplantation. The future directions of gene therapy include enhancement of lentiviral vector-based approaches, fine tuning of the conditioning regimen, and the design of safer vectors. Progress in genetic engineering bodes well for finding a cure for severe globin disorders.

Abstract
Alpha-thalassemia (α-thal) is probably the most prevalent monogenic condition in the world. Deletions are the most common types of mutations in α-thal, followed by point mutations and small insertion/deletion. In the context of national screening program for prevention of thalassemia and hemoglobinopathies in Iran, α-thal carriers have come to more attention. Therefore, the frequency and distribution of α-globin mutations in various regions of the country have been studied in recent years. A comprehensive search was performed in PubMed, Scopus, and national databases for finding reports on mutation detection in α-thal carriers and HbH disease with Iranian origin. The mutation data of 10849 α-thal carriers showed that -α3.7 and α-5NT were the most common deletional and nondeletional mutations, respectively. In HbH disease cases, the -α3.7/--MED was the most prevalent genotype. Overall, 42 different mutations have been identified in α-globin cluster reflecting the high heterogeneity of the mutations in Iranian populations.

Abstract
OBJECTIVES We performed molecular analysis to evaluate clinical implications of a rare nucleotide change, particularly when co-inherited with other known mutations in the globin clusters, in order to conduct an appropriate genetic counselling. METHODS Complete blood cell counts and high-performance liquid chromatography were the routine first level analysis for patients referred to our Hospital Center in Palermo to undergo the screening test for haemoglobinopathies. Sequencing analysis was the selected method for the phenotypic characterization, especially in case of new or very rare mutations in globin genes. RESULTS We report data of a rare single nucleotide variation at position -56 relative to transcription initiation site (NM_000518.4(HBB):c.-106G > C), identified in ten patients of Italian origin during the screening programme of the 'Sicilian population'. It was found in simple heterozygosity (n = 8), in association with beta haemoglobin variant Hb S (n = 1) and in heterozygosity with beta-thalassaemic allele IVS-I-1 G->A [(HBB):c.92 + 1G > A] and ααα anti3.7 rearrangement (n = 1). DISCUSSION Heterozygous subjects for this substitution showed normal haematological and electrophoretic features. Heterozygotes for this mutation and other defect in globin genes showed the classical phenotype of a healthy carrier, therefore it can be considered a benign variant that does not alter the production and function of haemoglobin. CONCLUSION This is another example of rare or new nucleotide variations whose identification and characterization is crucial in order to carry out appropriate genetic counselling to a potential risk couple.

Abstract
We report a large novel α-globin cluster deletion that we named - -PG (NG_000006.1: g.93628_542759del450131), in a Chinese family. This large deletion is approximately 450 kb long, spanning from upstream of the PolR3k gene at the 5' end to the RAB11FIP3 gene at the 3' end of chromosome 16p13.3. This deletion removes all the globin distal regulatory elements as well as the whole α-globin gene cluster. Patients with heterozygous - -PG/αα had red blood cell (RBC) indices consistent with α-thalassemia (α-thal) trait, but no apparent increase in a cancer tendency or mental disability, microcephaly, relative hypertelorism, unusual facies or genital anomalies.

Abstract
Background Recent studies on the variants in duplicated human alpha globin genes (HBA2 and HBA1) actively target the α-globin gene as molecular modulators for the treatment of β-thalassemia major. Identification of the exact position of variant in HBA1, HBA2 or its patchworks is mandatory to support the therapeutic aims in β-thalassemia major, by identifying specific modulators for the reactivation of fetal hemoglobin production. Hence, accurate identification of the variants in α-globin genes is crucial for the proper diagnosis, treatment and genetic counseling. Method The objective was to reveal the annotation errors produced in α-globin gene sequence analysis while using different analytic tools. An HBA2 gene sequence with the HBA2:c.95+2_95+6delTGAGG variant and a recently reported HBA12 gene convert have been taken as examples to prove annotation error in α-globin gene from different analytic tools. Results and discussion Although various bioinformatics tools used to predict variants are usually of high reliability, the current study using the an alpha globin 2 sequence with the HBA2:c.95+2_95+6delTGAGG variant and a recently reported HBA12 gene convert, has showcased ambiguous outputs among the three bioinformatics tools used and against the manual analytical method adopted. Conclusions This report emphasizes the necessity for caution in the usage of DNA sequence analysis tools during molecular diagnosis and the importance of the selection of more appropriate tools for analysis. Furthermore, ethnic specific sequences should be considered as reference sequence for the analysis to bypass sequence dissimilarities among diverse populations.

Abstract
α-Thalassemia is an inherited, autosomal recessive, disorder characterized by a microcytic hypochromic anemia. It is one of the most common monogenic gene disorders in the world population. The clinical severity varies from almost asymptomatic, to mild microcytic hypochromic, and to a lethal hemolytic condition, called Hb Bart's Hydrops Foetalis Syndrome. The molecular basis are usually deletions and less frequently, point mutations affecting the expression of one or more of the duplicated α-genes. The clinical variation and increase in disease severity is directly related to the decreased expression of one, two, three or four copies of the α-globin genes. Deletions and point mutations in the α-globin genes and their regulatory elements have been studied extensively in carriers and patients and these studies have given insight into the α-globin genes are regulated. By looking at naturally occurring deletions and point mutations, our knowledge of globin-gene regulation and expression will continue to increase and will lead to new targets of therapy.

Abstract
In the present study, a rare familial case of severe thalassemia with compound spontaneous mutations is reported. A 2.5-year-old boy, who suffered from severe anemia with yellowish skin, enlarged liver and spleen, was provided with a blood transfusion every 20 days to maintain hemoglobin levels between 90 and 100 g/l. Sanger sequencing combined with reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Gap-PCR revealed that the proband was a carrier of 4 compound heterozygous mutations: Hemoglobin subunit β (HBB):IVS-II-654(C>T)β+; Southeast Asian-type-hereditary persistence of fetal hemoglobin (SEA-HPFH); HBB:c316-148G>T; hemoglobin subunit α2 (HBA2):c.46G>A. The father of the proband was identified as a carrier of the heterozygous SEA-HPFH mutation, the mother was a carrier of compound heterozygous mutations of HBB:IVS-II-654(C>T) and HBA2:c.46G>A, and the elder sister was heterozygous for HBB:IVS-II-654(C>T)β+. Based on these genetic results, it was determined that the proband had both of heavy β-thalassemia and α-thalassemia. Upon human leukocyte antigen matching, bone marrow transplantation (BMT) was successfully performed on the proband by selecting his HLA-compatible sister as a donor. Following treatment, the proband was revealed to only carry the IVS-II-654(C>T)β+ heterozygous mutation, and further regular blood transfusions have been avoided; BMT results remained normal at six months follow-up.

An Aγ-globin G->A gene polymorphism associated with β 039 thalassemia globin gene and high fetal hemoglobin production. BMC MEDICAL GENETICS 2017; 18:93. [PMID: 28851297 PMCID: PMC5575872 DOI: 10.1186/s12881-017-0450-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/16/2015] [Accepted: 08/14/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND Increase of the expression of γ-globin gene and high production of fetal hemoglobin (HbF) in β-thalassemia patients is widely accepted as associated with a milder or even asymptomatic disease. The search for HbF-associated polymorphisms (such as the XmnI, BCL11A and MYB polymorphisms) has recently gained great attention, in order to stratify β-thalassemia patients with respect to expectancy of the first transfusion, need for annual intake of blood, response to HbF inducers (the most studied of which is hydroxyurea). METHODS Aγ-globin gene sequencing was performed on genomic DNA isolated from a total of 75 β-thalassemia patients, including 31 β039/β039, 33 β039/β+IVSI-110, 9 β+IVSI-110/β+IVSI-110, one β0IVSI-1/β+IVSI-6 and one β039/β+IVSI-6. RESULTS The results show that the rs368698783 polymorphism is present in β-thalassemia patients in the 5'UTR sequence (+25) of the Aγ-globin gene, known to affect the LYAR (human homologue of mouse Ly-1 antibody reactive clone) binding site 5'-GGTTAT-3'. This Aγ(+25 G->A) polymorphism is associated with the Gγ-globin-XmnI polymorphism and both are linked with the β039-globin gene, but not with the β+IVSI-110-globin gene. In agreement with the expectation that this mutation alters the LYAR binding activity, we found that the Aγ(+25 G->A) and Gγ-globin-XmnI polymorphisms are associated with high HbF in erythroid precursor cells isolated from β039/β039 thalassemia patients. CONCLUSIONS As a potential explanation of our findings, we hypothesize that in β-thalassemia the Gγ-globin-XmnI/Aγ-globin-(G->A) genotype is frequently under genetic linkage with β0-thalassemia mutations, but not with the β+-thalassemia mutation here studied (i.e. β+IVSI-110) and that this genetic combination has been selected within the population of β0-thalassemia patients, due to functional association with high HbF. Here we describe the characterization of the rs368698783 (+25 G->A) polymorphism of the Aγ-globin gene associated in β039 thalassemia patients with high HbF in erythroid precursor cells.

Abstract
A novel 811 bp deletion was first identified in two families of Nanning City, Guangxi Zhuang Autonomous Region, People's Republic of China (PRC). The molecular basis of this anomaly is a deletion from NG_000006.1: g.32945_33755, and is 20 bp upstream of the translation initiation codon of HBA2. From analyses of the blood indices of the two probands, the 811 bp deletion is an α+-thalassemia (α+-thal). This is the first report of this deletional thalassemia anywhere in the world.

Abstract
BACKGROUND Thalassaemia and variant haemoglobin are the most common severe monogenic disorders worldwide. AIMS To develop prenatal diagnosis programmes for the prevention of the most important haemoglobin disorders and identify healthy carriers of thalassaemia. METHODS Sequencing analysis was used to obtain complete data on gene structure and to correlate specific phenotypic expression with mutations, especially for new or very rare mutations in globin genes. RESULTS A rare single nucleotide variation, HBB:c.93-23T>C, located in nucleotide 108 of the first intervening sequence of the HBB gene, was identified. This variation was previously reported but its clinical significance was not known. Six heterozygous patients had this nucleotide variation and eight further cases co-inherited it together with other defects in the globin genes. Heterozygous subjects for this substitution showed normal haematological and electrophoretic features, whereas subjects who were compound heterozygotes for this mutation and another defect in globin genes showed the classic phenotype of a healthy carrier. CONCLUSION This nucleotide can be considered a single nucleotide polymorphism and not a thalassaemic mutation that reduces the production of haemoglobin. This is another example of a very rare nucleotide variation. Knowledge of this is important so that appropriate genetic counselling can be carried out of a couple potentially at risk, where one of the partners is a carrier of β-thalassaemia and the other is carrier of a nucleotide variation.

Abstract
Objective To reveal the prevalence and molecular characterization of (δβ)0‐thalassemia [(δβ)0‐thal] and hereditary persistence of fetal hemoglobin (HPFH) in the Chinese Zhuang population. Methods A total of 105 subjects with fetal hemoglobin (Hb F) level ≥5% from 14 204 unrelated ones were selected for the study. Multiplex ligation dependent probe amplification was firstly used to analyze dosage changes of the β‐globin gene cluster for associated with (δβ)0‐thal and HPFH mutations. The gap polymerase chain reaction was then performed to identify the deletions using the respective flanking primers. Hematologic data were recorded and correlated with the molecular findings. Results Twenty‐one (0.15%) subjects were diagnosed with Chinese Gγ(Aγδβ)0‐thal. Nine (0.06%) were diagnosed with Southeast Asia HPFH (SEA‐HPFH) deletion. Seventy‐five (0.53%) cases remained uncharacterized. Three genotypes for Chinese Gγ(Aγδβ)0‐thal and SEA‐HPFH deletion were identified, respectively. The genotype‐phenotype relationships were discussed. Conclusion Our study for the first time demonstrated that (δβ)0 and HPFH were not rare events, and molecular characterized Gγ(Aγδβ)0‐thal and HFPH mutations in the Chinese Zhuang population. The findings in our study will be useful in genetic counseling and prenatal diagnostic service of β‐thalassemia in this populations.

Abstract
Among microcytic hypochromic anemias, the most common disorders are iron deficiency anemia and co-pathological conditions such as α- or β-thalassemia (α- or β-thal) traits. The aim of the present study was to determine the frequency and prevalence of iron deficiency anemia and α- or β-thal traits based on clinical laboratory data across different ethnic groups in five districts of Sindh Province, Pakistan. The present retrospective study analyzed 3 years (2012-2015) of encoded and unlinked clinical laboratory data, and identified 3030 microcytic hypochromic anemia cases. The data contained complete blood counts (CBCs) with smear morphology examinations, serum ferritin levels, and hemoglobin (Hb) electrophoreses. After reviewing the data, 994 confirmed subjects (iron deficiency anemia and α- and β-thal traits) were then selected for the present study. The prevalence of α- and β-thal traits was highest in Badin district (35.27%), while the prevalence of iron deficiency anemia was highest in Larkana district (30.73%). According to the ethnic-wise distribution, higher numbers of α- and β-thal trait cases were seen in the Sindhi ethnic group [375 (64.21%) and 283 (69.02%), respectively] than in the other ethnic groups. In addition, a higher distribution of β-thal trait cases was observed in the Sindhi ethnic group [n = 327 (56%)] in α- and β-thal cases overall. Findings from the present study strongly suggested that screening is important not only for β-thal trait but also other traits as well. However, careful monitoring of CBC parameters, including red blood cell (RBC) indices and morphology, along with clinical findings are essential to diagnose carrier cases, especially in high prevalence areas.

Abstract
Hemoglobin (Hb) expression in the central nervous system is recently shown. Cooccurences of mental disorders (mainly bipolar disorder (BD) and tic disorders) with β- or α-thalassemia trait or erythrocytosis were witnessed, which may be due to peripheral or central hypoxia/hyperoxia or haplotypal gene interactions. β-Globin genes reside at 11p15.5 close to tyrosine hydroxylase, dopamine receptor DRD4 and Brain Derived Neurotrophic Factor, which involve in psychiatric diseases. α-Globin genes reside at 16p13.3 which associates with BD, tic disorders, ATR-16 Syndrome and Rubinstein Taybi Syndrome (RTS). CREB-Binding Protein (CEBBP)-gene is mutated in RTS, which commonly associates with mood disorders. 16p13.3 region also contains GRIN2A gene encoding N-methyl-d-aspartate receptor-2A and SSTR5 (Somatostatin Receptor-5), again involving in mental disorders. We demonstrated a protective role of minor HbA2 against post-partum episodes in BD and association of higher minor HbF (fetal hemoglobin) levels with family history of psychosis in a BD-patient cohort. HbA2 increases in cardiac ischemia and in mountain dwellers indicating its likely protection against ischemia/hypoxia. HMGIY, a repressive transcription factor of δ-globin chain of HbA2 is increased in lymphocytes of schizophrenics. In autism, deletional mutations were found in BCL11A gene, which cause persistence of HbF at high levels in adulthood. Also, certain polymorphisms in BCL11A strongly associate with schizophrenia. Further, many drugs from anabolic steroids to antimalarial agents elevate HbF and may cause mania. We ascribe a protective role to HbA2 and a maladaptive detrimental role to HbF in psychopathology. We believe that future studies on hemoglobins may pave to discover novel pathogenesis mechanisms in mental disorders.

Abstract
We report the hematological parameters and provide a rapid molecular analysis method for detection of Hb Wiangpapao [α44(CE2)Pro→Ser, CCG>TCG; HBA1: c.133C>T], a new α-globin variant found in a pregnant Thai woman. Her red cell indices were measured by an automated blood counter. The results were: red blood cell (RBC) count 4.03 × 1012/L, Hb 13.1 (g/dL), packed cell volume (PCV) 0.39 L/L, mean corpuscular volume (MCV) 97.0 fL, mean corpuscular hemoglobin (Hb) (MCH) 32.5 pg, mean corpuscular Hb concentration (MCHC) 33.4 g/dL, and RBC distribution width (RDW) 9.4%. The Hb typing by high performance liquid chromatography (HPLC) showed 13.6% abnormal Hb at a retention time of 2.20 min. that was difficult to distinguish from Hb A. On the capillary electrophoresis (CE) electropherogram, this hemoglobinopathy peak did not separate from the Hb A peak. DNA sequencing showed a C>T transition at the first position of codon 44 (CCG>TCG) of the α1-globin gene that led to a substitution of proline for serine. This mutation has not been recorded in the public databases. Therefore, we named it Hb Wiangpapao as it was first discovered in the Wiangpapao District, Chiang Rai, Thailand. The multiplex allele-specific polymerase chain reaction (ASPCR) for detection of Hb Wiangpapao was developed and revealed a 510 bp specifically amplified fragment. The better understanding of hematological characterizations and the newly developed multiplex ASPCR for diagnosis of Hb Wiangpapao are useful for genetic counseling and family education.

Abstract
We report here the clinical, hematological and molecular data in a 50-year-old patient with β-thalassemia intermedia (β-TI) caused by a homozygous β+ mutation on the β-globin gene polyadenylation (polyA) signal (AATAAA>AAAAAA). β Haplotype analysis was accomplished by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Haplotype and framework analysis showed that this mutation is associated with the [- - - - + + +] β haplotype and framework 1 (CCGCT) (FW1). This mutation was previously reported in the heterozygous state in association with the codon 9 (+TA) mutation in a β-TI patient originating from Tunisia. To the best of our knowledge, this is the first report describing this mutation in the homozygous state. The case reported here, coinherited Gilbert's syndrome, which is characterized by hyperbilirubinemia. This conclusion was reached by the investigation of the promoter region [A(TA)nTAA] motif of the UGT1A1 gene, showing the (TA)6/(TA)7 genotype.

Abstract
Inherited hemolytic anemias (IHAs) are genetic diseases that present with anemia due to the increased destruction of circulating abnormal RBCs. The RBC abnormalities are classified into the three major disorders of membranopathies, hemoglobinopathies, and enzymopathies. Traditional diagnosis of IHA has been performed via a step-wise process combining clinical and laboratory findings. Nowadays, the etiology of IHA accounts for germline mutations of the responsible genes coding for the structural components of RBCs. Recent advances in molecular technologies, including next-generation sequencing, inspire us to apply these technologies as a first-line approach for the identification of potential mutations and to determine the novel causative genes in patients with IHAs. We herein review the concept and strategy for the genetic diagnosis of IHAs and provide an overview of the preparations for clinical applications of the new molecular technologies.

Abstract
SIGNIFICANCE Oxidative stress and generation of free radicals are fundamental in initiating pathophysiological mechanisms leading to an inflammatory cascade resulting in high rates of morbidity and death from many inherited point mutation-derived hemoglobinopathies. Hemoglobin (Hb)E is the most common point mutation worldwide. The βE-globin gene is found in greatest frequency in Southeast Asia, including Thailand, Malaysia, Indonesia, Vietnam, Cambodia, and Laos. With the wave of worldwide migration, it is entering the gene pool of diverse populations with greater consequences than expected. CRITICAL ISSUES While HbE by itself presents as a mild anemia and a single gene for β-thalassemia is not serious, it remains unexplained why HbE/β-thalassemia (HbE/β-thal) is a grave disease with high morbidity and mortality. Patients often exhibit defective physical development, severe chronic anemia, and often die of cardiovascular disease and severe infections. Recent Advances: This article presents an overview of HbE/β-thal disease with an emphasis on new findings pointing to pathophysiological mechanisms derived from and initiated by the dysfunctional property of HbE as a reduced nitrite reductase concomitant with excess α-chains exacerbating unstable HbE, leading to a combination of nitric oxide imbalance, oxidative stress, and proinflammatory events. FUTURE DIRECTIONS Additionally, we present new therapeutic strategies that are based on the emerging molecular-level understanding of the pathophysiology of this and other hemoglobinopathies. These strategies are designed to short-circuit the inflammatory cascade leading to devastating chronic morbidity and fatal consequences. Antioxid. Redox Signal. 26, 794-813.

Abstract
We describe a new β-thalassemic mutation in a Chinese subject. This allele develops by insertion of one nucleotide (+T) between codons 138 and 139 in the third exon of the β-globin gene. The mutation causes a frameshift that leads to a termination codon at codon 139. In the heterozygote, this allele has the phenotype of classical β-thalassemia (β-thal) minor.

Abstract
The double heterozygosity for α and β chain variants leads to the formation of abnormal heterodimer hybrids, which could render laboratory diagnostics in a routine setting difficult. The following is the first report of a double heterozygosity for Hb Q-Thailand [α74(EF3)Asp→His; HBA1: c.223G>C] with α+-thalassemia (α+-thal) and Hb J-Bangkok [β56(D7)Gly→Asp; HBB: c.170G>A] found in a Chinese family. Both subjects were healthy with normal or borderline hematological parameters. Hemoglobin (Hb) analyses showed a novel variant, Hb Q-Thailand and Hb J-Bangkok. Family studies helped in the initial recognition and in making presumptive diagnoses, but definitive diagnoses of these cases with complex α and β chain variants could only be obtained after DNA analysis.

Abstract
BACKGROUND In most routine laboratories in Spain, the commonly used method for evaluating HbA1c is ion-exchange high performance liquid chromatography (HPLC). The presence of a variant of Hb may interfere with the quantification of HbA1c. AIMS Here, we report a novel haemoglobin variant, named Hb Moncloa, which was found during a routine health check at the Hospital Clínico San Carlos in Moncloa (Madrid), Spain. METHODS AND RESULTS Molecular characterization of β gene identified a novel transversion mutation [β80(EF4)Asn>Ser; HBB:c.242A>G]. CONCLUSIONS When there is no correlation between clinical, glycemic status and glycated haemoglobin of the patient, the chromatogram of HbA1c should be carefully checked to detect the possible presence of variants that cause interference in their measurement.

Abstract
We report a novel mutation on the α2-globin gene, Hb Nanning (HBA2:c.369_370delinsGA) detected in a Chinese family. This mutation gives rise to a previously undescribed hemoglobin (Hb) variant that was undetectable by various separation techniques. Both carriers of the mutation have mean corpuscular volume (MCV) and mean corpuscular Hb (MCH) values that are below normal, as would be predicted for an α+-thalassemia (α+-thal) patient.

Abstract
Extramedullary hematopoiesis (EMH) results from the extension of hematopoietic tissue beyond the confines of the bones. Since the initiation of regular transfusion programs from an early age for all thalassemia major (ΤΜ) patients, EMH has not been considered a clinical issue anymore. The present study aims to record the prevalence of EMH in chronically transfused ΤΜ patients followed at our institution and to investigate possible risk factors associated with its occurrence. The project was designed as a retrospective, nonexperimental, descriptive, exploratory study. In total, the study enrolled 104 patients. EMH was revealed in 15/104 (14%) patients. The presence of intravening sequence (IVS)-I-6 was significantly related with the development of EMH (p < 0.05). No other demographic or biological factor studied was found to be related with the presence of EMH. The study stresses a profound incidence of asymptomatic EMH in a solid group of well-transfused ΤΜ patients. Given the high incidence of the IVS-I-6 allele in the Mediterranean and Middle Eastern region, high-quality, prospective, multicenter studies could confirm the association of EMH occurrence with the presence of the IVS-I-6 mutation and further evaluate the exact role of this mutation in the EMH process.

Abstract
β-Thalassemia (β-thal) caused by mutations on the HBB gene is the most common single-gene disorder in the world. In this study, the HBB gene mutation was investigated in Hamadan province, Iran. Forty-one patients referred to a referral hospital were admitted to the study. DNA samples were extracted from peripheral blood. The HBB gene was sequenced in all recruited patients. Eleven mutations and eight polymorphisms were found in the studied patients. IVS-II-1 (G>A) (HBB: c.315+1 G>A) was the most common mutation, accounting for 25.61% of mutant alleles. Other mutations included codon 8 (-AA) (HBB: c.25-26delAA); IVS-I-110 (G>A) (HBB: c.93-21 G>A); codons 8/9 (+G) (HBB: c.27-28insG); IVS-I-1 (G>A) (HBB: c.92 G>A); codon 44 (-C) (HBB: c.135delC); codons 25/26 (+T) (HBB: c.78-79insT); IVS-I-130 (G>C) (HBB: c.93-1 G>C); -28 (A>C) (HBB: c.-78 A>C); codons 36/37 (-T) (HBB: c.112delT) and IVS-I-6 (T>C) (HBB: c.92+6 T>C). According to our findings, the IVS-II-1 mutation has the highest prevalence in Hamadan Province. It was found that the total frequency of the IVS-II-1, codons 25/26 (+T), codons 8/9 (+G), IVS-I-110 and IVS-I-1 mutations was 82.92%. Therefore, given these findings, it is recommended that these five mutations are screened for as a first step in laboratories without sequencing instruments, and that the rest of the gene is subsequently examined.

Abstract
β-Thalassemia (β-thal) is a hemolytic anemia that is caused by point mutations in most cases. The Brazilian population is highly heterogeneous and knowledge of the mutations that make up the genotypic profile of individuals can contribute information about the formation of the population and clinical condition of patients. In this study, we evaluated the mutations present in homozygous β-thal patients from Rio de Janeiro, Brazil. We analyzed 24 samples of peripheral blood of patients with homozygous β-thal. To identify the mutations, we carried out allele-specific-polymerase chain reaction (AS-PCR) and DNA sequencing. We found 11 different mutations on the β-globin gene. Among the most frequent mutations observed were HBB: c.92 + 6T>C, followed by HBB: c.93-21G>A, HBB: c.118C>T and HBB: c.92 + 1G>A. We also identified the rare mutation HBB: c.75T>A that was reported in an individual carrying Hb S (HBB: c.20A>T)/β-thal (HBB: c.75T>A) but not in Brazilian thalassemic patients, thus, this is the first report of this mutation in Brazilian β-thal patients. For its multiethnic character, Brazil has different mutations that cause β-thal and that are distributed with different frequencies according to the regions of the country. Our findings contribute to the description of the mutational profile of Brazilian thalassemic patients, showing wide heterogeneity and genetic variability.

Abstract
The prevalence of anemia is high in the population of Myanmar and hypochromic microcytic anemia (HMA) is predominant. The objective of our study was to determine the prevalence of anemia and causes of HMA among school children. A cross-sectional study was conducted on 239 children from Thanlyin and Insein Townships, Yangon Region, Myanmar. Complete blood count (CBC) and blood film morphology was examined on venous blood samples. Hypochromic microcytic anemia cases were subsequently analyzed for serum ferritin and cellulose acetate hemoglobin (Hb) electrophoresis. The prevalence of anemia was 46.4%; 27.6% had mild, while 18.8% had moderate anemia, and no case of severe anemia was detected. The mean Hb concentration was 11.7 ± 0.9 g/dL. The younger age group (8-11 years) had a significantly higher prevalence of anemia than the older age group (12-15 years) (p = 0.029). Blood film morphology revealed a 50.6% red blood cell (RBC) disorder; HMA was the most common type (70.2%). Out of 85 children with HMA, three children (3.5%) had iron deficiency and all had comorbidity with Hb AE (βA/βE) (Hb E trait). Hemoglobin electrophoresis illustrated that Hb AA (βA/βA) (31, 36.5%) and Hb AE (βA/βE) trait (31, 36.5%) were the most common types followed by β-thalassemia (β-thal) trait (19, 22.3%) and Hb EE (βE/βE) (homozygous Hb E; HBB: c.79G>A) (three, 3.5%). Hematocrit [or packed cell volume (PCV)], mean corpuscular volume (MCV), mean corpuscular Hb (MCH) and mean corpuscular Hb concentration (MCHC), showed a significant difference between Hb AE, Hb EE and β-thal trait (p = 0.029, 0.023, 0.015 and 0.01, respectively). Our findings will provide valuable information for the management of anemia in the Myanmar school-age population.

Abstract
α-Thalassemia (α-thal) is one of the most common genetic diseases in Thailand. Homozygosity of α-thal-1 (- -/- -) and compound heterozygosity of α-thal-1/α-thal-2 (- -/-α) leads to Hb Bart's (γ4) hydrops fetalis and Hb H (β4) disease, respectively. In order to better control and provide prevention of α-thal disease, the prevalence of α-thal-1 carriers and the types of genotypes in the Thai population should be known. A 7-year retrospective study, employing multiplex gap-polymerase chain reaction (gap-PCR) of 31,632 blood samples from Ramathibodi Hospital, Mahidol University, Bangkok, revealed an α-thal-1 carrier rate of 14.40% with the - -(SEA) (NG_000006.1: g.26264_45564del19301), - -(THAI) (NG_000006.1: g.10664_44164del33501) and - -(FIL) (NG_000006.1: g.11684_43534del31851) genotypes, constituting frequencies of 14.21, 0.18 and 0.01%, respectively. Although the - -(FIL) genotype is rare in the Thailand, its detection should be included in future α-thal screening programs.

Abstract
β-Thalassemia is one of the most prevalent forms of congenital blood disorders characterized by reduced hemoglobin levels with severe complications, affecting all dimensions of life. The mechanisms underlying the phenotypic heterogeneity of β-thalassemia are still poorly understood. We aimed to work over metabolite biomarkers to improve mechanistic understanding of phenotypic heterogeneity and hence better management of disorder at different levels. Untargeted serum metabolites were analyzed after protein precipitation and SPE (solid phase extraction) from 100 β-thalassemia patients and 61 healthy controls using GC-MS. 40 metabolites were identified having a significance difference between these two groups at probability of 0.05 and fold change >1.5. Out of these 40 metabolites, 17 were up-regulated while 23 were down-regulated. PCA and PLS-DA model was also created that revealed a fine separation with a sensitivity of 70% and specificity of 100% on external validation of samples. Metabolic pathway analysis revealed alteration in multiple pathways including glycolysis, pyruvate, propanoate, glycerophospholipid, galactose, fatty acid, starch and sucrose metabolism along with fatty acid elongation in mitochondria, glycerolipid, glyoxylate and dicarboxylate metabolism pointing towards the shift of metabolism in β-thalassemia patients in comparison to healthy individuals.

Abstract
Inheritance of mild mutations within the β-globin gene and coinheritance of α-thalassemia (α-thal) are known as two important genetic modifiers in β-thalassemia (β-thal) intermedia (β-TI). We aimed to evaluate the spectrum of β- and α-thal mutations in β-TI patients in Southeast Iran. Common β- and α-globin gene mutations were detected by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) and multiplex gap-PCR, respectively. There were 26 male (57.8%) and 19 female (42.2%) patients. HBB: c.92 + 5T > C [IVS-I-5 (G > C)] and HBB: c.-138C + 1G > A [IVS-II-I (G > A)] represented the prevalent alleles with respective frequencies of 60.0 and 10.0%. Other β-globin mutations included HBB: c.-138C > T [-88 (C > T)], HBB: c.27_28insG [frameshift codons (FSC) 8/9 (+G)], HBB: c.46delT [codon 15 (-T)], HBB: c.93-22_95del (IVS-I, 25 del), and the 619 bp deletion (NG_000007.3: g.71609_72227del619). The predominant genotypic combinations were β(0)/β(0) (68.9%), β(0)/β(+ )(8.9%) and β(+)/β(+ )(2.2%). Coinheritance of α-thal was observed in 33.0% of the patients, with the -α(3.7) (rightward) (NG_000006.1: g.34164_37967del3804) as the most common deletion (86.0%). One patient was diagnosed with the -α(4.2) (leftward) (AF221717) and one with the - -(MED) (g.24664_41064del16401) deletions, while no patients carried the -(α)(20.5) (g.15164_37864del22701), α(-5 nt) (HBA2: c.95 + 2_95_6delTGAGG) or codon 19 (-G) (HBA2: c.56delG) mutations. The alleviating molecular mechanism was not explainable by β(+ )or concurrent α-thal in more than half of our β-TI patients. This encourages conducting more studies to identify other contributing factors, especially Hb F-inducing genetic modifiers.

Abstract
Hemoglobin (Hb) is a potent oxidant outside the erythrocyte. The tyrosines α140 and β145 play an important role in the structure and function of Hb by forming switch and hinge contacts. These carboxy-terminal residues of the alpha and beta chains, respectively, were replaced to phenylalanine and several different methods were used to characterize the obtained mutants including a comet and plasmid DNA cleavage assay. It was observed that the genotoxic effect was 40% higher for αY140F compared with the wildtype, the βY145F and the double (αY140/β145F) mutants as determined by the comet assay. Cleavage of purified plasmid DNA after Hb application also revealed that the αY140F mutant showed 2-fold higher activity, while the βY145F and αY140/β145F mutants reduced the activity compared to wildtype Hb. This study clearly indicates that the penultimate tyrosines are involved in the genotoxicity of Hb.

Abstract
Thalassemia and sickle cell disease (SCD) are disorders of hemoglobin that affect millions of people worldwide. The carrier states for these diseases arose as common, balanced polymorphisms during human history because they afforded protection against severe forms of malaria. These complex, multisystem diseases are reviewed here with a focus on current standards of clinical management and recent research findings. The importance of a comprehensive, multidisciplinary and lifelong system of care is also emphasized.

Abstract
BACKGROUND β-thalassemia is the most common monogenic disorder in Iran, and one of the challenges in the screening of the carriers is the coinheritance of α-thalassemia mutations. In the view of high prevalence of α-thalassemia mutations in many parts of the country, the aim of this study was to determine the carrier frequency of common alpha deletions, as a secondary modifier in clinical manifestations of beta thalassemia, in known beta-thalassemia carriers and some hematology parameter changes. METHODS The study included families referred from different primary health care centers with microcytic hypochromic anemia [MCV<80fl; MCH<27 pg] and A2>3.4%]. Genomic DNA was extracted from peripheral blood leukocytes by salting out method. For common β-globin gene mutation analysis, amplification refractory mutation system- polymerase chain reaction (ARMS-PCR) and for rare β-thal alleles, DNA sequencing were used. Also, for investigation of common α-globin gene cluster deletions (-α3.7, -α4.2, --MED and -α20.5), multiplex Gap-PCR was performed. RESULTS Among 227 β-thalassemia minor individuals studied, α-globin gene deletions were found in 43 cases: 37 heterozygote -α3.7 (16.3%), 5 homo -α3.7 (2.2%) and 1 --MED (0.44%). Also, the co-inheritance of α-globin gene deletion and triplication was not found in the studied individuals. CONCLUSION Although it is highly recommended that physicians and genetic counselors involved in the screening program of beta-thal major in the country consider this phenomenon because of high prevalence of this coinheritance, hematologic indices changes are very slight.
