Abstract

Background: Arylamine N-acetyltransferase 2 (NAT2) polymorphism was previously reported to have association with the risk of drug toxicities and the development of various diseases. Previous research on the Indonesian population, especially Javanese and Sundanese, showed that there were 33% NAT2 slow acetylator phenotype. The aim of this study was to map the NAT2 variation in the Malay ethnic to gain a deeper insight into NAT2 haplotypic composition in this ethnic.Methods: 50 healthy samples from the Indonesian Malay ethnic were obtained. They were interviewed about their ethnic backgrounds for the last three generations. DNA was extracted from peripheral blood and NAT2 genotyping was done using the PCR direct Sequencing. Data were compiled according to the genotype and allele frequencies estimated from the observed numbers of each specific allele. Haplotype reconstruction was performed using PHASE v2.1.1 software.Results: We found 7 haplotypes consisting of 6 SNPs and 14 NAT2 genotype variations in Indonesian Malay population. The most frequent allele was NAT2*6A (38%) which was classified as a slow acetylator allele. According to bimodal distribution, the predicted phenotype of the Malay population was composed of 62% rapid acetylator and 38% slow acetylator. According to trimodal distribution, the predicted phenotypes for rapid, intermediate and slow acetylators were 10%, 52% and 38% respectively.Conclusion: Our result indicates the presence of the allelic distribution and revealed the most frequent acetylator status and phenotype for the Indonesian Malay population. The result of this study will be helpful for future epidemiological or clinical studies and for understanding the genetic basis of acetylation polymorphism in Indonesia.

Abstract

Beta-thalassemia merupakan gangguan hematologis autosomal yang secara genetis mengakibatkan berkurangnya sintesis beta-globin di hemoglobin. Beta-talasemia sebagian besar disebabkan oleh mutasi titik, insersi atau delesi dalam gen beta-globin yang terletak pada lengan pendek kromosom 11. Organisasi Kesehatan Dunia (WHO) memperkirakan terdapat sekitar 1,5% dari populasi global (80-90 juta orang) adalah pembawa ?-thalassemia. Tidak ada studi komprehensif untuk mendeteksi pembawa beta-thalassemia di Indonesia, terutama untuk mutasi delesi 619 bp, yang mencakup ekson 3 dan memiliki prevalensi yang tinggi. Kami menggunakan metode gap-PCR yang di-kombinasikan dengan metode elektroforesis gel untuk memper-kirakan adanya mutasi delesi 619 bp pada 48 siswa Fakultas Kedokteran Universitas YARSI dengan etnis Melayu. Analisis Blast hasil sekuensing dari ketiga sampel menunjukkan bahwa terdapat similaritas 98% antara hasil amplifikasi dengan ke daerah gen beta-globin pada kromosom 11 (No. Aksesi U01317.1). Berdasarkan hasil visualisasi elektroforesis gel, semua produk PCR dari 48 sampel, menunjukkan bahwa semua sampel tidak membawa mutasi delesi 619 bp yang ditunjukkan dengan ukuran produk PCR yang sama dari semua sampel, yaitu berukuran 1.457 bp dan 2.291 bp dari PCR I dan 1.212 bp dari PCR II.Beta-thalassaemia is an autosomal haematological disorder resulting in a genetically deficient synthesis of the ?-globin chain in haemoglobin. It is mostly caused by point mutations, a small deletions or insertions within the beta-globin gene which is located as a cluster on the short arm of chromosome 11. The World Health Organization has estimated that about 1.5% of the global population (80 to 90 million people) were carriers of ?-thalassemia. There are no comprehensive study to detect carrier of ?-thalassemia in Indonesia especially for 619 bp deletion mutation, which encompasses exon 3, that has greater prevalence. We used gap-PCR combined with gel electrophoresis methods to roughly screen the presence of major indel mutation in 48 Medical Faculty, Universitas YARSI students with Malay ethnic. To validate whether the PCR product obtained is the beta-globin gene, a direct sequencing of 3 PCR products were performed. The Blast analysis of the sequence was also done using NCBI database. The result showed that the PCR products obtained in this study showed 98% identity to human beta-globin gene region on chromosome 11 (No. Acc. U01317.1). In the electrophoresis of all PCR products of 48 samples, the result showed that all the samples did not carry any major indel mutation showing by the presence of similar length of PCR products in gel electrophoresis, which has 1.457 bp and 2.291 bp product from PCR I and 1.212 bp product from PCR II.

Abstract

Previous studies suggested that genetic factors exerted huge influence in susceptibility to Tuberculosis. Tumor Necrosis Factor Alpha (TNF-a), which is encoded by the TNF gene, play a role on pulmonary macrophage function in isolating and controlling Mycobacterium tuberculosis infection. Polymorphisms on the promoter region of the TNF gene have been predicted to affect its transcriptional activity. Therefore, these polymorphisms are an excellent candidate to further study the role of TNF-a in susceptibility to Tuberculosis. 100 pulmonary tuberculosis patients (case) and 100 healthy individuals (controls) were recruited for this pilot study. DNA samples from cases and controls were genotyped for the TNF -238G A SNP (rs361525) using LightSNip genotyping assay. Our results showed no significant difference in the distribution of TNF -238 genotypes in case and control subjects (P = 0.4335). Further investigation on TNF -238 allele frequencies between case and control studies also yields no significant difference (P=1.000; OR=1.000; %95CI [0.246597 ? 4.055200]) which may suggest that there are no association with predisposition to Tuberculosis infection. In conclusion, this pilot study showed that the TNF -238G A SNP is not associated with susceptibility to Tuberculosis.

Abstract

Human leucocyte antigen (HLA) adalah protein penyaji antigen yang lokus genetiknya berada di kromosom 6p21 dengan ukuran sebesar 3,8 Mb dan berasosiasi dengan lebih dari 100 penyakit berbeda yang  kebanyakan merupakan penyakit autoimun. Proses HLA-typing menggunakan sekuensing Sanger masih memberikan ambiguitas terhadap determinasi alel, low-throughput, dan membutuhkan biaya besar untuk sampel dalam jumlah besar. Next generation sequencing (NGS) menjadi metode yang dapat mengatasi kelemahan sekuensing Sanger. MiSeq dari Illumina merupakan salah satu NGS yang digunakan untuk HLA-typing. MiSeq memberikan kemudahan preparasi dan fleksibilitas metode yang dapat dikembangkan sesuai dengan kebutuhan laboratorium penelitian. Penelitian dilakukan di Laboratorium Molekular Genetik, Laboratorium Terpadu Universitas YARSI pada empat orang mahasiswa Fakultas Kedokteran Universitas YARSI etnik Melayu selama periode Mei–Desember 2014. Hasil menunjukkan terdapat total 546 SNP heterozygous, 888 SNP homozygous, 25 insersi, dan 23 delesi dari keseluruhan 11 sampel amplikon dengan coverage 2.106,536x dengan 2x25 siklus pembacaan. Optimasi metode HLA-typing dapat dikatakan berhasil dengan mengombinasikan long-range PCR dan pemilihan ukuran library 300–600 bp. [MKB. 2015;47(3):152–159]Kata kunci: HLA Kelas I, MiSeq, next generation sequencingDevelopment of Class I HLA Gene In-House HLA-Typing Methods (HLA A, HLA B, and HLA C) using Next Generation Sequencing Illumina MiSeqAbstractHuman leukocyte antigen (HLA) is a 3.8 Mb protein presenting antigen whose genetic locus is located in chromosome 6p21 area and have association with more than 100 different diseases that are mostly autoimmune diseases. HLA-typing process using Sanger sequencing still  creates ambiguity in the  determination of  alleles, low-throughput, and costly as it requires a large quantity of sample. Next generation sequencing (NGS) is a method that can overcome the drawbacks of Sanger sequencing. MiSeq Illumina is one of the NGSs that are used for HLA-typing. This study was conducted at the Laboratory of Molecular, Universitas YARSI in a period from May to December 2014. MiSeq provides convenience and flexibility in the preparation methods that can be developed according to the needs of the research laboratory. The results showed that there were a total of 546 SNPs that were heterozygous, 888homozygous SNP, 25 insertions and 23 deletions from the overall 11 amplicon samples with an average coverage with 2x25 read length of  2,106,536x. Our protocol generates good result as we combined long PCR amplicon and size selection method to 300–600 bp fragment.  [MKB. 2015;47(3):152–159]Key words: HLA Class I, MiSeq, next generation sequencing DOI: 10.15395/mkb.v47n3.389

Abstract

Background: Asthma is a multifactorial disease that encompasses a multitude of genetic and environmental factors. One such factor is the disintegrin and metalloprotein-33 (ADAM33) gene, which is correlated with asthma and bronchial hyperresponsiveness. Previous studies conducted on Asian populations have reported a significant association between rs2787094 polymorphism in the ADAM33 gene and asthma. Methods: Our study involved 153 Indonesian participants. TaqMan genotyping assay was used to analyze rs2787094 polymorphism in the ADAM33 gene. Results: No significant association was detected between the allele and genotype frequencies of rs2787094 and asthma in the case and control subjects (p = 1.00). The distribution of rs2787094 genotypes in healthy controls was CC (12.1%), CG (42.1%), and GG (45.8%). The genotype distribution in Indonesians was similar to East Asians in 1,000 genomes dataset. Conclusions: This is the first study to investigate the association between rs2787094 polymorphism in the ADAM33 gene and asthma in the Indonesian population and concluded that it is not associated. Future studies with larger sample sizes and more single nucleotide polymorphisms in the ADAM33 gene are needed to validate these results.

Abstract

Tuberculosis (TB) is still a major public health problem in Indonesia. Anti-tuberculosis drug-induced hepatotoxicity (DIH) is common side effect leading to changes in treatment regimens, and the less effective second-line treatments. Several risk factors such as age, sex, body mass index (BMI) and acetylization status for hepatotoxicity were suggested in previous studies but in the fact, those are often not related to DIH incidence after receiving standard TB treatment regimen. The aim of this study was to asses the role of risk factors in the DIH incidence in pulmonary TB patients receiving standard TB treatment regimen in Dr. Soetomo Hospital, Surabaya. Study design was analytic observational with case control. The subjects were 30 TB DIH patients and 31 TB non-DIH patients receiving standard national TB program therapy. DIH severity was divided based on International DIH Expert Working Group. Demographic data and BMI status were taken from medical records. The age classification are ≥35 years old and <35 years old as one of the risk factors studied. DNA sequencing was used to assess single-nucleotide polymorphisms in NAT2 coding region to evaluate acetylator status from blood samples. The risk factors were evaluated using chi-square test and Mantel-Haenszel test. Significant association between low BMI and DIH in general was identified (OR=3.017; 95% CI=1.029-8.845) and more significant association between low BMI and moderate DIH (OR=15.833; 95% CI=1.792-139.922). Age, sex, and acetylization status has no significant correlation with DIH incidence in general. Significant association between slow acetylator phenotype and incidence of moderate DIH was identified (OR=7.125; 95% CI= 1.309-38.711). In conclusion, some risk factors were correlated to DIH incidence in pulmonary TB patientsreceiving standart TB treatment regimen.

Abstract

Tuberculosis (TB) remains Indonesia's leading infectious disease. Hepatotoxicity is the most common side effect of TB first-line medication therapy in TB patients. GSTM1 and GSTT1 are glutathione S-transferase (GST) genes involved in the detoxification of various toxic compounds such as drugs. The development of fast and simple methods for null genotyping of GSTM1/GSTT1 could facilitate large pharmacogenetic studies and the clinical application of personalized drug dose adjustment according to the patient's genetic profile. The aim of this research was to develop a multiple PCR method for simultaneous amplification of GSTM1/GSTT1 genes for molecular analysis. A total of 25 samples of TB patients were used to validate the method consisting of TB patients with hepatotoxicity and without hepatotoxicity. Our result showed the genotype frequency of the GSTM1 null genotype was 90% in TB patients with hepatotoxicity and 100% in TB patients without hepatotoxicity. The frequency of the GSTT1 null genotype in TB patients with hepatotoxicity was 90%, whereas in TB patients without hepatotoxicity was 80%. The sequencing results on the positive samples showed a similarity of 99% to the GenBank NCBI. Our study was successful in detecting GSTM1 and GSTT1 null genotypes using the multiplex PCR method in TB patients. Further study needs to be done with larger sample of TB patients.

Abstract

Fruit juice is a healthy beverage. However, we must be careful in handling or consuming such juice, especially in relation to its storage time. The Prophet of Muhammed PBUH in his hadith prohibits to drink fruit juices that have been stored for more than 3 days, as its legal status changes from Halal into Haram.In accordance with the development of science and technology, many methods could be used to measure alcohol content in a sample; such as Gas Chromatography-Mass Spectroscopy method (GC-MS). Therefore the objective of this research was to analyze the alcohol content of various fruit juices made with or without the addition of yeast and  being stored within 1, 2, and 3 days using GC-MS, as well as its relation to the hadith Matn of the Prophet Muhammad PBUH regarding its law. Results showed that alcohol (ethanol) content of various fruit juices : red grapes, green grapes, dates, pomegranate and durian, made without the addition of yeast which stored for 3 days, in consecutive order were 0.524; 0.144; 0.214; 0.143 and 0.314% v/v. While alcohol (ethanol) content of various fruit juices : red grapes, green grapes, dates, pomegranate and durian, made with the addition of 10 g/L yeast were  and stored for 3 days were 0.618; 0.921; 0.901; 0.575 and 1.202% v/v constitutively. Alcohol content of red grapes fruit juices of 0.524% v/v was the highest alcohol content (in juices) which is still Halal to be consumed.
