Loss-of-Function Variants in SUPT5H as Modifying Factors in Beta-Thalassemia

Loss-of-Function Variants in SUPT5H as Modifying Factors in Beta-Thalassemia investigates how genetic variants affecting SUPT5H may influence disease severity in β-thalassemia. The study provides evidence that SUPT5H loss-of-function variants can act as modifying factors, supporting the role of genetic modifiers in explaining variability in clinical phenotype among patients.

Genetic Polymorphisms Associated with Fetal Hemoglobin (HbF) Levels and F-Cell Numbers: A Systematic Review of Genome-Wide Association Studies

Genetic Polymorphisms Associated with Fetal Hemoglobin (HbF) Levels and F-Cell Numbers: A Systematic Review of Genome-Wide Association Studies summarizes evidence from GWAS on genetic variants linked to HbF regulation and F-cell production. The review highlights key loci and polymorphisms influencing HbF levels, supporting their relevance as modifiers of disease severity and as potential targets for therapeutic strategies in hemoglobinopathies.

ACMG/AMP-Based Variant Classification of a Novel HBA2 Variant (HBA2: C.297del, Hb Taiping) in Compound Heterozygosity With Hb Adana (HBA2:C.179G>A) Causing Non-Deletional Hb H Disease

ACMG/AMP-Based Variant Classification of a Novel HBA2 Variant (HBA2:c.297del, Hb Taiping) in Compound Heterozygosity With Hb Adana (HBA2:c.179G>A) Causing Non-Deletional Hb H Disease reports the identification and characterisation of a novel α-globin variant, Hb Taiping, in a family with α-thalassaemia. The study applies ACMG/AMP guidelines adapted for globin genes to classify the variant as pathogenic and demonstrates that, when co-inherited with Hb Adana, it results in a severe non-deletional Hb H disease phenotype. These findings expand the mutational spectrum of α-thalassaemia and highlight the importance of accurate variant classification for diagnosis, genetic counselling, and clinical management.
