First Report of Co‐Inheritance of Hemoglobin British Columbia (HBB:c.304G>A) and β‐Thalassemia IVS‐I‐6 (HBB:c.92+6T>C): Clinical Characterization of an Iranian Case

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
ABSTRACT Background Hemoglobin British Columbia is a rare high‐oxygen‐affinity β‐globin variant caused by the HBB:c.304G>A substitution. Its detection is exceptionally uncommon, particularly in the Middle East, and may lead to diagnostic pitfalls when relying solely on hemoglobin separation techniques.

Performance Evaluation of a Premier Resolution HPLC System for Detecting Hemoglobin Constant Spring, Hemoglobin Paksé, and Coexisting α‐ and β‐Thalassemia Mutations

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This study compared Premier Resolution HPLC with Capillary Electrophoresis for detecting HbCS/Hb Paksé variants and coexisting thalassemia mutations. Premier Resolution HPLC demonstrated superior performance with 50% fewer false negative cases (11 vs. 22) compared to Capillary Electrophoresis, particularly in heterozygous cases.

Mild thalassemia: the result of interactions of alpha and beta thalassemia genes [PDF]

open access: yesJournal of Clinical Investigation, 1970
Homozygous thalassemia is due to inherited unbalanced synthesis of the alpha- or beta-chains of hemoglobin. Clinical severity may be in part related to the extent of alpha:beta imbalance. Two families are presented that illustrate this concept. Thalassemia in these individuals was evaluated by clinical and genetic criteria. The relative rates of alpha-

Progress in researches on disease burden and health service utilization of beta-thalassemia patients in China

open access: yesZhongguo gonggong weisheng, 2023
Thalassemia is an inherited hemoglobin disorder clinically categorized into alpha and beta thalassemia. Severe beta-thalassemia patients commonly experience anemia during infancy and progressively deteriorate, necessitating long-term blood transfusion to

Beta‐Thalassemia in Spain: Results From the National Thalassemia Registry and Molecular Analysis of Patients With Transfusion‐Dependent Thalassemia

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This nationwide registry‐based study describes the clinical and molecular characteristics of 78 patients with transfusion‐dependent beta‐thalassemia in Spain. Comprehensive genetic analysis revealed marked molecular heterogeneity, with 24 HBB mutations identified and a predominance of β0 genotypes, alongside generally effective transfusion and iron ...

Elevated Hemoglobin A2: A Molecular Revisited, and Implications to β‐Thalassemia Screening

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
In Thailand, the Hb A2 cut‐off value for β‐thalassemia carrier has been changed from 4.0% to 3.6% since 2015. We examined the molecular basis of β‐thalassemia in a large cohort of Thai subjects with this change. The molecular basis of β‐thalassemia was updated, and a change in the Hb A2 cut‐off can alter this spectrum.

Impact of genotype on endocrinal complications of Children with Alpha-thalassemia in China

open access: yesScientific Reports, 2017
Alpha-thalassemia occurs with high frenquency in China. Four common α-globin gene deletion mutations (–SEA, -α3.7, and -α4.2, Haemoglobin Constant Spring (CS) mutation) were identified in Chinese patients.

Rare double heterozygosity for poly A(A>G) and CD17(A>T) of beta thalassemia intermedia in a Chinese family

open access: yesHematology Reports, 2019
Beta thalassemia is a hereditary disorder resulted from mutations in the β globin gene leading to alpha/beta imbalance, ineffective erythropoiesis, and chronic anemia.

Cerebral Blood Transit in Sickle Cell Anemia

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...

Heterozygous Beta‐Thalassaemia in Pregnancy: Two Rare Causes of Severe Fetal Anemia Requiring Intrauterine Blood Transfusions

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Aim In this article, we present two cases of severe fetal hemolytic anemia based on a beta‐thalassaemia trait inherited from a single parent. Results These cases, presented at 20 and 28 weeks' gestation, necessitated intra‐uterine blood transfusions.
