  1. Association of the functional polymorphism in the catechol-O-methyltransferase gene with schizophrenia in the three ethnic groups of the Malaysian population
    Wan CL, Zainal NZ, Lian LH, Mohamed Z
    Psychiatry Res, 2011 Aug 30;189(1):67-71.
    PMID: 21414668 DOI: 10.1016/j.psychres.2011.02.008
    The catechol-O-methyltransferase (COMT) gene is a candidate gene for schizophrenia as its encoded enzyme is involved in the metabolic inactivation of dopamine and noradrenaline. Several molecular genetic studies thus far have demonstrated that the COMT functional polymorphism of Val158Met is susceptible with schizophrenia. Hence, the present study aims to determine this genetic association of this SNP in the three major ethnic groups of the Malaysian population. A total of 317 patients (79 Malays, 154 Chinese and 84 Indians) meeting DSM-IV criteria for schizophrenia and 417 healthy subjects (160 Malays, 164 Chinese and 93 Indians) were recruited. A PCR-RFLP method was used to determine the genotypes and alleles present. We found a significant association of genotypes within the total pooled samples, as well as in the female subgroup, with a higher frequency of heterozygotes in schizophrenia subjects. However, there were no significant differences in allele and genotype frequency between the schizophrenic patients and normal controls in all three ethnic groups. Our current findings suggest that the Val158Met polymorphism has a weak association with schizophrenia in the Malaysian population and does not play a major role in conferring susceptibility to the schizophrenia in any of the three major local ethnicities.

    PURPOSE: Prostate cancer differs markedly in incidence across ethnic groups. Since this disease is influenced by complex genetics, it is many genetic factors may affect the level of susceptibility to development of the disease. In this study, four Y-linked short tandem repeats (STRs), DYS388, DYS435, DYS437, and DYS439, were genotyped to compare Malaysian prostate cancer patients and normal control males.

    MATERIALS AND METHODS: A total of 175 subjects comprising 84 patients and 91 healthy individuals were recruited. Multiplex PCR was optimized to co-amplify DYS388, DYS435, DYS437, and DYS439 loci. All samples were genotyped for alleles of four DYS loci using a Genetic Analysis System.

    RESULTS: Of all DYS loci, allele 10 (A) of DYS388 had a significantly lower incidence of disease in compare with other alleles of this locus, while a higher incidence of disease was found among males who had either allele 12 (C) of DYS388 or allele 14 (E) of DYS439. Moreover, a total of 47 different haplotypes comprising different alleles of four DYS loci were found among the whole study samples, of which haplotypes AABC and CAAA showed a lower and higher frequency among cases than controls, respectively.

    CONCLUSIONS: It is likely that Malaysian males who belong to Y-lineages with either allele 12 of DYS388, allele 14 of DYS439, or haplotype CAAA are more susceptible to develop prostate cancer, while those belonging to lineages with allele 10 of DYS388 or haplotype AABC are more resistant to the disease.

    Chiu YH, Chang YC, Chang YH, Niu DM, Yang YL, Ye J, et al.
    J Hum Genet, 2012 Feb;57(2):145-52.
    PMID: 22237589 DOI: 10.1038/jhg.2011.146
    The enzyme 6-pyruvoyl-tetrahydropterin synthase (PTPS, gene symbol: PTS) is involved in the second step of the de novo biosynthesis of tetrahydrobiopterin (BH4), which is a vital cofactor of nitric oxide synthases and three types of aromatic amino acid hydroxylases; the latter are important enzymes in the production of neurotransmitters. We conducted a study of PTS mutations in East Asia, including Taiwan, Mainland China, Japan, South Korea, the Philippines, Thailand and Malaysia. A total of 43 mutations were identified, comprising 22 previously reported mutations and 21 new discovered mutations. Among these, the c.155A>G, c.259C>T, c. 272A>G, c.286G>A and c.84-291A>G mutations were the most common PTS mutations in East Asia, while the c.58T>C and c.243G>A mutations were, respectively, specific to Filipinos and Japanese originating from Okinawa. Further studies demonstrated that each of the mutations listed above was in linkage disequilibrium to a specific allele of polymorphic microsatellite marker, D11S1347. These results suggest the presence of founder effects that have affected these frequent mutations in East Asia populations. In this context, D11S1347 should become one of the most reliable polymorphic markers for use in prenatal diagnosis among PTPS deficient families, especially where mutations are yet to be identified.

  5. Fulltext Lack of association of ABCB1 haplotypes on five loci with response to treatment in epilepsy
    Haerian BS, Lim KS, Mohamed EH, Tan HJ, Tan CT, Raymond AA, et al.
    Seizure, 2011 Sep;20(7):546-53.
    PMID: 21530324 DOI: 10.1016/j.seizure.2011.04.003
    Approximately one third of newly treated epilepsy patients do not respond to antiepileptic drugs (AEDs). Overexpression of P-glycoprotein (P-gp) efflux transporter has been proposed to have a critical role in causing resistance to AEDs. P-gp is a product of the ATP-binding cassette subfamily B member 1 (ABCB1) gene. The purpose of this study was to investigate a possible link between ABCB1 rs3789243 C>T, C1236T, G2677T/A, rs6949448 C>T, and C3435T haplotypes with response to carbamazepine (CBZ) or sodium valproate (VPA) monotherapy in Malaysian epilepsy patients. No ABCB1 haplotype association was found with response to either CBZ or VPA monotherapy in the Chinese, Indian, and Malay patients. C3435 allele carriers of the Indian males with cryptogenic epilepsy were more prone to resistance to either CBZ or VPA than carriers of T allele. Moreover, rs3789243T allele carriers of Malay females with symptomatic epilepsy were more resistant to either CBZ or VPA than C allele carriers. Our findings suggest that the ABCB1 rs3789243 C>T, C1236T, G2677T/A, rs6949448 C>T, and C3435T haplotypes do not contribute to response to AED treatment in epilepsy.

    PMID: 20930417
    CYP1A2 play an important role in the metabolism of many carcinogens and clinically important drugs. CYP1A2 activity has been found to be influenced by the presence of polymorphic variants which were reported to display wide interethnic variation. This study investigates the frequency distribution and linkage disequilibrium patterns of CYP1A2 genetic polymorphisms, and characterize their haplotype structures in three healthy Asian populations in Singapore (Chinese, Malay, and Indian). The entire CYP1A2 gene was screened in 126 healthy subjects from all three ethnic groups (N=42 each). A total of 25 polymorphisms was identified, of which nine were novel. The polymorphisms, -2467delT and -163C>A were detected at high frequencies in all Asian ethnic groups. Significant interethnic differences were observed in the genotypic frequency distribution of IVS2-99G>A (P<0.01) and 1548C>T (P=0.05) across the three ethnic groups while -163C>A (P=0.02) was found to differ between Chinese and Malays. Haplotype analyses revealed four to six major haplotypes in each ethnic population which accounted for more than 60% of the cumulative haplotype frequencies. Future studies should be done to investigate the functional roles of these haplotypes.

    Teh LK, Zahri MK, Zakaria ZA, Ismail R, Salleh MZ
    J Clin Pharm Ther, 2010 Dec;35(6):723-8.
    PMID: 21054465 DOI: 10.1111/j.1365-2710.2009.01146.x
    CYP2C8 is involved in the cytochrome P450 (CYP) epoxygenase pathway. Arachidonic acid metabolites such as epoxyeicosatrienenoic acids and hydroxyeicosatetrenoic acids, produced may have a role in hypertension. We aimed to develop a medium through-put method for screening samples of known and new mutations of CYP2C8 using denaturing high performance liquid chromatography (DHPLC).

  9. Fulltext Association of Arg72Pro of P53 polymorphism with colorectal cancer susceptibility risk in Malaysian population
    Aizat AA, Shahpudin SN, Mustapha MA, Zakaria Z, Sidek AS, Abu Hassan MR, et al.
    Asian Pac J Cancer Prev, 2011;12(11):2909-13.
    PMID: 22393962
    BACKGROUND: Colorectal cancer (CRC) results from the interaction between environmental exposures and genetic predisposition factors.

    AIMS: A case control study was designed and to investigate the genotype frequencies of P53Arg72Pro polymorphism in Malaysian CRC patients and healthy controls and to determine the associated risk of this polymorphism with CRC predisposition.

    METHODS: In this case-control study, peripheral blood samples of 202 sporadic CRC patients and 201 normal controls were collected, DNA extracted and genotyped using the polymerase chain reaction - restriction fragment length polymorphism (PCR-RFLP) technique.

    RESULTS: Genotype analysis showed the frequency of homozygous variant (Pro/Pro) genotype (21%) to be significantly higher in cases compared to controls (13%), (p=0.013). On examining the association between variant genotypes and CRC risk, the Pro/Pro homozygous variant genotype showed significantly higher risk association with CRC susceptibility (OR: 2.047, CI: 1.063-4.044, p=0.033). When stratified according to age, we observed that, individuals aged above 50 years and carriers of pro/pro genotype had significantly higher risk with OR: 3.642, CI: 1.166-11.378, p=0.026.

    CONCLUSIONS: Our results suggest that the codon 72 SNP which results in amino acid substitution of Arginine to Proline in cell cycle regulatory gene P53, is associated with sporadic CRC risk and carriers of Pro/Pro genotype and more than 50 years old may have high susceptibility.

    Edinur HA, Zafarina Z, Spínola H, Nurhaslindawaty AR, Panneerchelvam S, Norazmi MN
    Hum Immunol, 2009 Jul;70(7):518-26.
    PMID: 19364514 DOI: 10.1016/j.humimm.2009.04.003
    In this study, human leukocyte antigen (HLA) class I and II were examined through sequence-specific primer typing in 176 unrelated individuals from six Malay subethnic groups of Peninsular Malaysia: Kelantan (n = 25), Minangkabau (34), Jawa (30), Bugis (31), Banjar (33), and Rawa (23). The most common HLA alleles in all groups were A*24 (26-41%), Cw*07 (24-32%), B*15 (22-30%), DRB1*12 (15-36%), and DQB1*03 (25-51%). The Malay subethnic groups studied demonstrated a close relationship to each other and to other Asian populations, despite specific differences between them. Banjar, Bugis, and Jawa Malays demonstrated no significant difference from each other, which could be a result of their related origin from the islands around the Java Sea. These three Malay subethnic groups were then collapsed into one group, which also helped to increase the sample number and sharpen statistical results. Minangkabau and Rawa Malays exhibited high similarities in allele group and haplotype frequencies, which could be a consequence of their common origin from Sumatera. Kelantan Malays, in addition to their statistically significant differences compared with the other groups, also exhibited differences on the most frequent haplotypes, which are almost absent in the other subethnic groups studied.

  11. Fulltext Interleukin-6 promoter polymorphisms (-174 G/C) in Malaysian patients with systemic lupus erythematosus
    Chua KH, Kee BP, Tan SY, Lian LH
    Braz. J. Med. Biol. Res., 2009 Jun;42(6):551-5.
    PMID: 19448905 DOI: 10.1590/s0100-879x2009000600012
    Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that involves the inflammation of various organs upon deposition of immune complexes and is characterized by uncontrolled B cell hyperactivity. Despite intensive research on the etiology of the disease, the exact cause of the onset of SLE is unknown. The pathogenesis of the disease has been proposed to be associated with the imbalance of T helper type 1 (Th1) and Th2 cytokine activities. Elevated serum levels of interleukin-6 (IL-6), a Th2 cytokine with various functions in the regulation of human biological systems, are observed in SLE patients. In the present study, 100 Malaysian SLE patients and 100 controls were evaluated in order to determine the association of polymorphisms existing in the promoter region of the IL-6 gene with the onset of SLE. The homozygous G genotype was found to be significant in SLE patients (chi(2) = 33.754; P = 0.00000000625), whereas the heterozygous G/C genotype was significant in the controls (chi(2)= 25.087; P = 0.000000548). We suggest that the C allele might have a masking effect on the G allele when both alleles are present in heterozygous individuals. However, we did not observe any significant association of the homozygous C allele with the onset of SLE or with protection from the disease (chi(2) = 1.684; P = 0.194366).

    PMID: 19414156 DOI: 10.1016/j.fsigen.2008.07.007
    17 Y-STRs (DYS456, DYS389I, DYS390, DYS389II, DYS458, DYS19, DYS385a/b, DYS393, DYS391, DYS439, DYS635 or Y-GATA C4, DYS392, Y-GATA H4, DYS437, DYS438 and DYS448) have been analyzed in 320 male individuals from Sarawak, an eastern state of Malaysia on the Borneo island using the AmpFlSTR Y-filer (Applied Biosystems, Foster City, CA). These individuals were from three indigenous ethnic groups in Sarawak comprising of 103 Ibans, 113 Bidayuhs and 104 Melanaus. The observed 17-loci haplotypes and the individual allele frequencies for each locus were estimated, whilst the locus diversity, haplotype diversity and discrimination capacity were calculated in the three groups. Analysis of molecular variance (AMOVA) indicated that 87.6% of the haplotypic variation was found within population and 12.4% between populations (fixation index F(ST)=0.124, p=0.000). This study has revealed that the indigenous populations in Sarawak are distinctly different to each other, and to the three major ethnic groups in Malaysia (Malays, Chinese and Indians), with the Melanaus having a strikingly high degree of shared haplotypes within. There are rare unusual variants and microvariants that were not present in Malaysian Malay, Chinese or Indian groups. In addition, occurrences of DYS385 duplications which were only noticeably present in Chinese group previously was also observed in the Iban group whilst null alleles were detected at several Y-loci (namely DYS19, DYS392, DYS389II and DYS448) in the Iban and Melanau groups.

  13. Comparison of single nucleotide polymorphisms in the human interleukin-10 gene promoter between rheumatoid arthritis patients and normal subjects in Malaysia
    Hee CS, Gun SC, Naidu R, Das Gupta E, Somnath SD, Radhakrishnan AK
    Mod Rheumatol, 2007;17(5):429-35.
    PMID: 17929139 DOI: 10.1007/s10165-007-0612-9
    In this study, three single nucleotide polymorphisms (SNPs) located within the promoter of the human interleukin (IL)-10 gene [rs1800896 (position: -1087G>A), rs1800871 (position: -824C>T) and rs1800872 (position: -597C>A)] were investigated in 84 rheumatoid arthritis (RA) patients and 95 age- and sex-matched healthy subjects using polymerase chain reaction-restriction fragment length polymorphism method. Production of IL-10 by peripheral blood lymphocytes from the RA patients and healthy subjects cultured in the presence of Concanavalin A (Con A) was determined by using enzyme-linked immunosorbent assay. The results show that the distribution of the IL-10 genotypes did not differ significantly between RA patients and healthy subjects (P>0.05). However, a significant difference was observed in allele frequencies of -824CT, -824TT, -597CA, and -597AA between the RA patients and healthy volunteers (P=0.04). The -1087A/-824T/-597A (ATA) haplotype, which comprises all mutant alleles, was associated with lower IL-10 production when compared with the other haplotypes. In contrast, the RA patients who did not display the ATA haplotype produced significantly higher levels of IL-10 when compared with those carrying either one (P=0.012) or two (P=0.005) ATA haplotypes. Our findings suggest that there is an association between SNPs in the promoter of the human IL-10 gene and susceptibility to RA.

    PMID: 17044869
    Factor VII (FVII) is an independent risk factor for coronary artery disease. Three polymorphisms of the factor VII gene (F7) were studied in a group of healthy newborns comprising 561 Chinese, 398 Malays and 226 Asian Indians from Singapore. The allele frequencies of 3 polymorphisms (R353Q, Promoter 0/10bp Del/Ins and Intron 7) in the FVII gene were ascertained through genotyping by polymerase chain reaction and restriction digestion of amplified fragments. In Chinese the minor allele frequencies are Q: 0.04, Ins: 0.03, R7: 0.44; Malays, Q: 0.06, Ins: 0.10, R7: 0.41; and Indians, Q: 0.25, Ins: 0.23, R7: 0.43. Strong linkage disequilibrium (Delta > 0.7) is observed between the 0/10 bp and the R353Q sites in all ethnic groups. We conclude that: (i) the prevalence of the minor Q and Ins alleles of the R353Q and 0/10 bp polymorphisms are significantly higher in the Indian newborns than the Chinese and Malays; (ii) the Q allele is significantly associated (p = 0.01) with a lower plasma FVII coagulant level in the Indian and Malay neonates; and this polymorphism explains up to 3.8% of the variance in FVII coagulant levels; (iii) there is no significant difference in allele frequencies of the three polymorphisms between neonates with and without family histories of CAD.

    There are significant differences in the prevalence and severity of neonatal jaundice among various populations. Recently, it has been reported that a mutation of the UGT1A1 gene, glycine to arginine at codon 71 (G71R), is related to the development of neonatal jaundice in East Asian populations. However, whether the G71R mutation contributes to the high incidence of neonatal jaundice in different Asian populations remains unknown. The authors screened for this mutation in the Javanese-Indonesian and Malay-Malaysian populations.

    PMID: 16266403
    Mitochondria are eukaryotic cytoplasmic organelles responsible for oxidative phosphorylation. The C to A nucleotide transversion in the NADH dehydrogenase subunit 2 (MT-ND2) coding region of mitochondrial DNA has been reported to be associated with plasma lipid levels, adult onset diseases and longevity. We have examined the role of this polymorphism in relation to plasma lipid levels and age in a total of 713 healthy individuals belonging to 3 ethnic groups in Singapore. The frequency of the A allele was significantly higher (p < 0.05) among the Chinese (0.15) in comparison to the Malays (0.05) and Indians (0.02). No significant difference in the frequency of the allele was observed between healthy and coronary artery disease subjects, and between age-stratified subjects. We found that the polymorphism is significantly associated in an ethnic- and gender-specific manner with plasma apoB levels in the Chinese males (p < 0.05). This is the first epidemiological report of the mt5178 C > A polymorphism and its association with plasma lipid levels in Asian populations outside Japan.

    Haghvirdizadeh P, Ramachandran V, Etemad A, Heidari F, Ghodsian N, Bin Ismail N, et al.
    J Diabetes Res, 2015;2015:289846.
    PMID: 26451383 DOI: 10.1155/2015/289846
    BACKGROUND: Type 2 diabetes mellitus (T2DM) is a complex polygenic disorder characterized by impaired insulin resistance, insulin secretion, and dysregulation of lipid and protein metabolism with environmental and genetic factors. ATP-binding cassette transporter A1 (ABCA1) gene polymorphisms are reported as the one of the genetic risk factors for T2DM in various populations with conflicting results. This study was conducted based on PCR-HRM to determine the frequency of ABCA1 gene by rs2230806 (R219K), rs1800977 (C69T), and rs9282541 (R230C) polymorphisms Malaysian subjects.

    METHODS: A total of 164 T2DM and 165 controls were recruited and their genotypes for ABCA1 gene polymorphisms were determined based on the real time high resolution melting analysis.

    RESULTS: There was a significant difference between the subjects in terms of age, BMI, FPG, HbA1c, HDL, LDL, and TG (P < 0.05). There was a significant association between HOM of R219K (P = 0.005), among Malaysian subjects; moreover, allele frequency revealed the significant difference in A allele of R219K (P = 0.003). But, there was no significant difference in genotypic and allelic frequencies of C69T and R230C polymorphism.

    CONCLUSION: R219K polymorphism of ABCA1 gene can be considered as a genetic risk factor for T2DM subjects among Malaysians.
