A variety of mutations causing beta-thalassemia (beta-thal) have been seen in the Indian subcontinent. We report eight families in whom two novel mutations [codon 16 (C>T), IVS-II-613 (C>T)] and three rare mutations [codons 22/23/24 (-7 bp) (-AAGTTGG), -87 (C>A), codon 15 (-T)] were encountered among 375 beta-thal heterozygotes. They were referred to us for molecular characterization or prenatal diagnosis during a period of 2 years. Haplotyping was also done for linkage analysis.

Background: δβ-thalassemia/HPFH is an uncommon hemoglobinopathy characterized by decreased or the total absence of production of δ- and β-globin and increased HbF levels. Both these disorders have variable genotype and phenotype, but significant overlap in the clinical and laboratory findings. Given the lack of literature in this regard, the study aimed to estimate the prevalence of the disease and evaluate its clinical, hematological, and molecular profile in India.

Sex is a fundamental biological variable that influences immune system function, with sex chromosomes (X and Y) playing a central role in these differences. Despite substantial evidence of disparities in immune responses between males and females, biomedical research has historically overlooked sex as a critical factor. This oversight has contributed to the observed disparities in susceptibility to autoimmune diseases, infectious diseases, and malignancies between the sexes.

Background: Disorders of lipid metabolism are critical factors in the progression of chronic lymphocytic leukemia (CLL). However, the characteristics of lipid metabolism and related regulatory mechanisms of CLL remain unclear.
Methods: Hence, we identified altered metabolites and aberrant lipid metabolism pathways in patients with CLL by ultra-high-performance liquid chromatography-mass spectrometry-based non-targeted lipidomics.

Hypomethylating agents (HMAs) such as azacytidine and decitabine are FDA-approved chemotherapy drugs for hematologic malignancy. By inhibiting DNA methyltransferases, HMAs reactivate tumor suppressor genes (TSGs) and endogenous double-stranded RNAs (dsRNAs) that limit tumor growth and trigger apoptosis via viral mimicry. Yet, HMAs show limited effects in many solid tumors despite the strong induction of TSGs and dsRNAs.

Inter-individual variability in drug responses is significantly influenced by genetic factors, underscoring the importance of population-specific pharmacogenomic studies to optimize clinical outcomes. In this study, we analyzed whole genome sequencing data from 949 unrelated Thai individuals and conducted an in-depth analysis of 3239 genes involved in drug pharmacokinetics, pharmacodynamics, or immune-mediated adverse drug reactions. We identified 43 single nucleotide polymorphisms (SNPs), 134 diplotypes, and 15 human leukocyte antigen (HLA) alleles, all with moderate to high clinical significance.
