Summary
This study identified common thalassemia mutations in East Java, Indonesia. Hb E was the most prevalent, highlighting the need for broader research to understand genetic diversity for prevention programs.
Area of Science:
- Genetics
- Molecular Biology
- Public Health
Background:
- Thalassemia prevention programs require precise knowledge of prevalent mutations.
- Indonesia's multi-ethnic population presents unique challenges for genetic disease management.
- Defining the spectrum of beta-thalassemia mutations is crucial for effective public health strategies.
Purpose of the Study:
- To determine the prevalence of common beta-thalassemia mutations in East Java, Indonesia.
- To provide foundational data for developing targeted thalassemia prevention programs in the region.
Main Methods:
- Direct DNA sequencing of beta-globin genes was performed.
- Analysis included 17 transfusion-dependent thalassemia patients from Dr. Soetomo Hospital, Surabaya.
- 34 independent chromosomes were analyzed to identify mutation frequencies.
Main Results:
- Hemoglobin E (c.79 G>A p. Glu27Lys) was the most frequent mutation at 47.0%.
- Other prevalent mutations included IVS-I-5 G>C (20.6%) and codon 35 (-C) (17.6%).
- A homogeneous distribution of mutations was observed, though differing from previous reports.
Conclusions:
- Preliminary findings reveal a distinct spectrum of prevalent thalassemia mutations in East Java.
- Further large-scale studies across diverse geographical areas are necessary.
- Comprehensive molecular characterization is essential for national thalassemia control efforts.

01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

01:11Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase
Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
