    The whole mitochondrial genome of the pest fruit fly Bactrocera arecae was obtained from next-generation sequencing of genomic DNA. It had a total length of 15,900 bp, consisting of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a non-coding region (A + T-rich control region). The control region (952 bp) was flanked by rrnS and trnI genes. The start codons included 6 ATG, 3 ATT and 1 each of ATA, ATC, GTG and TCG. Eight TAA, two TAG, one incomplete TA and two incomplete T stop codons were represented in the protein-coding genes. The cloverleaf structure for trnS1 lacked the D-loop, and that of trnN and trnF lacked the TΨC-loop. Molecular phylogeny based on 13 protein-coding genes was concordant with 37 mitochondrial genes, with B. arecae having closest genetic affinity to B. tryoni. The subgenus Bactrocera of Dacini tribe and the Dacinae subfamily (Dacini and Ceratitidini tribes) were monophyletic. The whole mitogenome of B. arecae will serve as a useful dataset for studying the genetics, systematics and phylogenetic relationships of the many species of Bactrocera genus in particular, and tephritid fruit flies in general.

    The present study was carried out to characterize the causative genetic mutation in a medium-sized Malaysian Chinese pedigree of three generations affected with familial adenomatous polyposis (FAP). Clinical data and genetic studies revealed considerable phenotypic variability in affected individuals in this family. Blood was obtained from members of the FAP-01 family and genomic DNA was extracted. Mutation screening of the adenomatous polyposis coli (APC) gene was carried out using the single strand conformation polymorphism (SSCP) technique. The possibility of exon skipping was predicted by splicing motif recognition software (ESEfinder release2.0). SSCP results showed mobility shifts in exon 8 of the APC gene which segregated with affected members of the family. Sequence analysis revealed that the affected individuals are heterozygous for a C847T transition, whilst all the unaffected family members and control individuals are homozygous C at the same position. This nucleotide substitution generates a stop codon at amino acid position 283, in place of the usual arginine (Arg283Ter). We conclude that an Arg283Ter mutation in the APC gene is causative of the FAP phenotype in this family, although there is considerable variation in the presentation of this disease among affected individuals. Computational analysis predicts that this mutation occurs within sequences that may function as splicing signals, so that the sequence change may affect normal splicing.

    Preimplantation genetic diagnosis (PGD) of monogenic autosomal hereditary disorders following assisted conception usually involves the removal of one or two blastomeres from preimplantation embryos. However, the amount of DNA from a single blastomere is insufficient to amplify the region of interest. Hence, the whole genome amplification (WGA) method is performed prior to amplifying the genes of interest before analysis of DNA material through polymerase chain reaction (PCR).

    Two optimization strategies, codon usage modification and glycine supplementation, were adopted to improve the extracellular production of Bacillus sp. NR5 UPM β-cyclodextrin glycosyltransferase (CGT-BS) in recombinant Escherichia coli. Several rare codons were eliminated and replaced with the ones favored by E. coli cells, resulting in an increased codon adaptation index (CAI) from 0.67 to 0.78. The cultivation of the codon modified recombinant E. coli following optimization of glycine supplementation enhanced the secretion of β-CGTase activity up to 2.2-fold at 12 h of cultivation as compared to the control. β-CGTase secreted into the culture medium by the transformant reached 65.524 U/mL at post-induction temperature of 37 °C with addition of 1.2 mM glycine and induced at 2 h of cultivation. A 20.1-fold purity of the recombinant β-CGTase was obtained when purified through a combination of diafiltration and nickel-nitrilotriacetic acid (Ni-NTA) affinity chromatography. This combined strategy doubled the extracellular β-CGTase production when compared to the single approach, hence offering the potential of enhancing the expression of extracellular enzymes, particularly β-CGTase by the recombinant E. coli.

    The combined overlap extension PCR (COE-PCR) method developed in this work combines the strengths of the overlap extension PCR (OE-PCR) method with the speed and ease of the asymmetrical overlap extension (AOE-PCR) method. This combined method allows up to 6 base pairs to be mutated at a time and requires a total of 40-45 PCR cycles. A total of eight mutagenesis experiments were successfully carried out, with each experiment mutating between two to six base pairs. Up to four adjacent codons were changed in a single experiment. This method is especially useful for codon optimization, where doublet or triplet rare codons can be changed using a single mutagenic primer set, in a single experiment.

    Alzheimer's disease (AD) is the most common form of dementia, which can be categorized into two main forms: early onset AD and late onset AD. The genetic background of early onset AD is well understood, and three genes, the APP, PSEN1, and PSEN2 have been identified as causative genes. In the current study, we tested three siblings from Malaysia who were diagnosed with early onset dementia, as well as their available family members. The family history was positive as their deceased father was similarly affected. Patients were tested for mutations in APP, PSEN1, PSEN2, and PRNP. A novel variant, E280K, was discovered in exon 8 of PSEN1 in the three siblings. In silico analyses with SIFT, SNAP, and PolyPhen2 prediction tools and three-dimensional modeling were performed, and the results suggested that the mutation is probably a pathogenic variant. Two additional pathogenic mutations were previously been described for codon 280, E280A, and E280G, which could support the importance of the E280 residue in the PS1 protein contributing to the pathogenic nature of E280K. Additional ten family members were screened for the E280K mutation, and all of them were negative. Six of them presented with a variety of neuropsychiatric symptoms, including learning disabilities, epilepsy, and schizophrenia, while four family members were asymptomatic. A novel PRNP G127S mutation was found in a step-niece of the three siblings harboring the PSEN1 E280K mutation. In silico predictions for PRNP G127S mutation suggested that this might be possibly a damaging variant. Additional studies to characterize PRNP G127S would be necessary to further understand the effects of this mutation.

    Malaria cases persist in some remote areas in Sabah and Sarawak despite the ongoing and largely successful malaria control programme conducted by the Vector Borne Disease Control Programme, Ministry Of Health, Malaysia. Point mutations in the genes that encode the two enzymes involved in the folate biosynthesis pathway, dihydrofolate reductase (DHFR) and dihydropteroate synthase (DHPS) enzymes confer resistance to pyrimethamine and sulfadoxine respectively, in both Plasmodium falciparum and P. vivax. The aim of the current study was to determine the mutation on both pvdhfr at codon 13, 33, 57, 58, 61, 117, and 173 and pvdhps genes at codon 383 and 553, which are potentially associated with resistance to pyrimethamine and sulfadoxine in P. vivax samples in Sabah.

    We have completely sequenced the genomes of two Nipah virus (NiV) isolates, one from the throat secretion and the other from the cerebrospinal fluid (CSF) of the sole surviving encephalitic patient with positive CSF virus isolation in Malaysia. The two genomes have 18246 nucleotides each and differ by only 4 nucleotides. The NiV genome is 12 nucleotides longer than the Hendra virus (HeV) genome and both genomes have identical leader and trailer sequence lengths and hexamer-phasing positions for all their genes. Both NiV and HeV are also very closely related with respect to their genomic end sequences, gene start and stop signals, P gene-editing signals and deduced amino acid sequences of nucleocapsid protein, phosphoprotein, matrix protein, fusion protein, glycoprotein and RNA polymerase. The existing evidence demonstrates a clear need for the creation of a new genus within the subfamily Paramyxovirinae to accommodate the close similarities between NiV and HeV and their significant differences from other members of the subfamily.

    Familial multiple intestinal atresias is an autosomal recessive disease with or without combined immunodeficiency. In the last year, several reports have described mutations in the gene TTC7A as causal to the disease in different populations. However, exact correlation between different genotypes and various phenotypes are not clear. In this study, we report identification of novel compound heterozygous mutations in TTC7A gene in a Malay girl with familial multiple intestinal atresias and severe combined immunodeficiency (MIA-SCID) by whole exome sequencing. We found two mutations in TTC7A: one that destroyed a putative splicing acceptor at the junction of intron 17/exon 18 and one that introduced a stop codon that would truncate the last two amino acids of the encoded protein. Reviewing the recent reports on TTC7A mutations reveals correlation between the position and nature of the mutations with patient survival and clinical manifestations. Examination of public databases also suggests carrier status for healthy individuals, making a case for population screening on this gene, especially in populations with suspected frequent founder mutations.

    In this study, we analyzed the Rc and Rd genes that are responsible for the coloration of rice pericarps from six upland rice varieties. We also examined the association of pericarp coloration to the single nucleotide polymorphism in 9-cis-epoxycarotenoid dioxygenase 2 (NCED2), a key gene involved in abscisic acid (ABA) biosynthesis. Our findings demonstrated that all the upland rice varieties analyzed have a Rd gene which encodes a complete dihydroflavonol-4-reductase without early translational termination codon irrespective of their pericarp colors. However, the upland rice varieties with white pericarps were found to have a defective Rc gene with a 14-base deletion at exon 7 which could disrupt the function of a positive regulator of proanthocyanidin biosynthesis. In addition, the NCED2 genes from the upland rice varieties with white pericarps in this study have a C-allele while the NCED2 genes from Pandasan Red, Tomou and Taragang varieties that bear red pericarps were found to have a T-allele which was reported to be associated with a higher ABA level in upland rice. A better understanding of the gene sequences of upland rice varieties with red pericarp may provide important information for rice breeding programs.

    Introduction: Elimination of viral hepatitis as a major public health threat by 2030 was announced by the Global Health Sector Strategy (GHSS) on viral hepatitis in 2016. Hepatitis C is one of the major causes of liver cirrhosis and liver cancer. Complications as a results of hepatitis C infection can be prevented as hepatitis C infection is now con-sidered as a curable disease with the availability of Direct Acting Agents (DAAs). However, the main barrier towards treating and curing all HCV infected patients is a high cost of DAAs. The treatment regime of hepatitis C infection in Malaysia is sofosbuvir and daclastavir, an NS5A inhibitor. Daclastavir was reported as inherently resistant to HCV GT 3. Thus, this study aimed to develop an assay to detect the resistance associated substitution (RAS) towards the NS5A inhibitor among HCV GT 3 infected patients. Methods: Samples for the study were obtained from various hospitals in Malaysia. The samples were collected from DAAs naïve HCV GT 3 infected patients. From the literature review, a specific assay was chosen with different sets of primers were selected for the study. The DNA sequences of NS5A region of HCV genome were submitted to the geno2pheno [HCV] resistance database by Max Planck Institut (MPI) Informatics to yield RAS. Results: Suitable primers were identified based on generated amplicons produced for the samples which NS5A region were successfully sequenced. Results were obtained based on the 213 codon generated from the population based Sanger sequencing. RAS/ RASs towards Daclastavir were produced and the susceptibility result towards the drug was generated. Conclusion: The assay was successfully optimised and able to generate drug resistance results towards Daclastavir which might have impacts on the duration of treatment and/or inclusion of ribavirin in managing HCV infected patients in Malaysia.

    In the last 20 years, severe wheat stem rust outbreaks have been recorded in Africa, Europe, and Central Asia. This previously well controlled disease, caused by the fungus Puccinia graminis f. sp. tritici, has reemerged as a major threat to wheat cultivation. The stem rust (Sr) resistance gene Sr22 encodes a nucleotide-binding and leucine-rich repeat receptor which confers resistance to the highly virulent African stem rust isolate Ug99. Here, we show that the Sr22 gene is conserved among grasses in the Triticeae and Poeae lineages. Triticeae species contain syntenic loci with single-copy orthologs of Sr22 on chromosome 7, except Hordeum vulgare, which has experienced major expansions and rearrangements at the locus. We also describe 14 Sr22 sequence variants obtained from both Triticum boeoticum and the domesticated form of this species, T. monococcum, which have been postulated to encode both functional and nonfunctional Sr22 alleles. The nucleotide sequence analysis of these alleles identified historical sequence exchange resulting from recombination or gene conversion, including breakpoints within codons, which expanded the coding potential at these positions by introduction of nonsynonymous substitutions. Three Sr22 alleles were transformed into wheat cultivar Fielder and two postulated resistant alleles from Schomburgk (hexaploid wheat introgressed with T. boeoticum segment carrying Sr22) and T. monococcum accession PI190945, respectively, conferred resistance to P. graminis f. sp. tritici race TTKSK, thereby unequivocally confirming Sr22 effectiveness against Ug99. The third allele from accession PI573523, previously believed to confer susceptibility, was confirmed as nonfunctional against Australian P. graminis f. sp. tritici race 98-1,2,3,5,6.[Formula: see text] Copyright © 2020 The Author(s).

    Introduction: Tuberculosis (TB) still remains a public health problem worldwide and the emergence of drug resistant TB (DR-TB) has worsened the situation as it is difficult and expensive to treat. The characterization of the genetic mutations underlying streptomycin resistance may be helpful in developing rapid detection methods which may guide clinicians in making therapeutic decisions. The aim of this study is to detect mutations causing streptomycin (STR) resistance in Mycobacterium tuberculosis isolates from Sabah. Methods: Susceptibility testing was carried out in MGIT system for 42 Mycobacterium tuberculosis clinical isolates. The drug resistant isolates were subject to whole genome sequencing and in-silico analysis was performed to detect the mutations in the sequence of the rpsL gene known to confer resistance to anti-tuberculous drugs. Results: Of the 42 positive isolates, 27 (64.3%) are shown to be susceptible towards first line drugs (FLDs) while 15 (35.7%) isolates were mono- and multiple resistant to the FLDs. Our findings reveal that the isolate 145 possess mutations at codon 43 within rpsL gene with amino acid change A to G (K43R). Conclusion: Findings from this study enable us to expand our knowledge of mutations causing drug resistance in Mycobacterium tuberculosis and the point mutations, which can be used as the potential marker for detection of drug resistant isolates.

    Most individuals affected with DYT1 dystonia have a heterozygous 3-bp deletion in the TOR1A gene (c.907_909delGAG). The mutation appears to act through a dominant-negative mechanism compromising normal torsinA function, and it is proposed that reducing mutant torsinA may normalize torsinA activity. In this study, we used an engineered Cas9 variant from Streptococcus pyogenes (SpCas9-VRQR) to target the mutation in the TOR1A gene in order to disrupt mutant torsinA in DYT1 patient fibroblasts. Selective targeting of the DYT1 allele was highly efficient with most common non-homologous end joining (NHEJ) edits, leading to a predicted premature stop codon with loss of the torsinA C terminus (delta 302-332 aa). Structural analysis predicted a functionally inactive status of this truncated torsinA due to the loss of residues associated with ATPase activity and binding to LULL1. Immunoblotting showed a reduction of the torsinA protein level in Cas9-edited DYT1 fibroblasts, and a functional assay using HSV infection indicated a phenotypic recovery toward that observed in control fibroblasts. These findings suggest that the selective disruption of the mutant TOR1A allele using CRISPR-Cas9 inactivates mutant torsinA, allowing the remaining wild-type torsinA to exert normal function.

    The Trigonopoma pauciperforatum or the redstripe rasbora is a cyprinid commonly found in marshes and swampy areas with slight acidic tannin-stained water in the tropics. In this study, the complete mitogenome sequence of T. pauciperforatum was first amplified in two parts using two pairs of overlapping primers and then sequenced. The size of the mitogenome is 16,707 bp, encompassing 22 transfer RNA genes, 13 protein-coding genes, two ribosomal RNA genes and a putative control region. Identical gene organisation was detected between this species and other family members. The heavy strand accommodates 28 genes while the light strand houses the remaining nine genes. Most protein-coding genes utilise ATG as start codon except for COI gene which uses GTG instead. The terminal associated sequence (TAS), central conserved sequence block (CSB-F, CSB-D and CSB-E) as well as variable sequence block (CSB-1, CSB-2 and CSB-3) are conserved in the control region. The maximum likelihood phylogenetic tree revealed the divergence of T. pauciperforatum from the basal region of the major clade, where its evolutionary relationships with Boraras maculatus, Rasbora cephalotaenia and R. daniconius are poorly resolved as suggested by the low bootstrap values. This work contributes towards the genetic resource enrichment for peat swamp conservation and comprehensive in-depth comparisons across other phylogenetic researches done on the Rasbora-related genus.

    Chloroquine resistance transporter of Plasmodium falciparum (PfCRT) is a food vacuolar transmembrane protein that mediates susceptibility of the parasite to chloroquine. A mutation at K76T of the Pfcrt gene is a key determinant for chloroquine resistance phenotype. In the absence of drug pressure, in vitro growth rate of chloroquine-resistance parasites was outcompeted by wild-type parasites unless intragenic compensatory mutations occurred. Chloroquine-resistant P. falciparum bearing the Cam734 haplotype known to circulate in endemic areas of Cambodia bordering Thailand contains 9 mutations in Pfcrt and exhibits both chloroquine resistance and comparable growth rate to the chloroquine-sensitive 3D7 strain. To analyze the evolution of the Cam734 haplotype, codon-based analysis was performed by using the mixed effects model of evolution (MEME), branch-site random effects likelihood (BR-REL) and other related methods. Results revealed that the Cam734 haplotype has evolved distinctively from other known mutant haplotypes including the most common Dd2 haplotype in Southeast Asia. Evidence of episodic positive selection was detected at codon 144, characterized by c.[430G>T; 431C>T] (p.A144F), known to be indispensable for both chloroquine resistance and restoration of growth rate of the parasites. To survey the prevalence of mutations at codons 76 and 144 in Pfcrt among Thai isolates, restriction fragment analysis of 548 P. falciparum isolates collected from six endemic provinces of Thailand during 1991 and 2016 was performed. The 144F Pfcrt mutant was detected in 7 (1.28%) isolates. All Thai isolates analyzed herein harbored a mutation at codon 76 whilst the wild-type parasite was not found. The low prevalence of isolates bearing the mutation 144F in PfCRT could imply little or lack of survival advantage of this mutant in endemic areas of Thailand where the wild-type parasites seem to be absent or extremely rare.

    Infection by hepatitis B virus (HBV) is a major global health-care problem. HBV is an accepted factor in the elevated risks for liver disease such as cirrhosis and development of hepatocellular carcinoma. This problem is particularly prevalent in the Asia-Pacific region which includes Malaysia. During infection, the hepatitis B e antigen (HBeAg) is produced in the hosts. This antigen is an important serological marker for diagnosing chronic hepatitis B. Seroconversion to anti-body (anti-HBe) corresponds to the improvement of disease prognosis. However, certain mutations such as the core promoter dual mutations (A1762G1764→T1762A1764), the codon 15 variants (C1858/ T1858) and the precore stop codon mutations (TGG→TAG) can affect the HBeAg expression. This has diagnostic and clinical implications. Besides that, the HBV can be grouped into eight genotypes (A to H). Moreover, genotypic subtypes and recombinants have been observed as well. Studies have observed that these can differ in their affiliations with the mutations above as well as with disease prognosis.

    Glutaric aciduria type 1 (GA1) is an autosomal recessive metabolic disorder caused by deficiency of glutaryl-CoA dehydrogenase enzyme encoded by the GCDH gene. In this study, we presented the clinical and molecular findings of seven GA1 patients in Malaysia. All the patients were symptomatic from infancy and diagnosed clinically from large excretion of glutaric and 3-hydroxyglutaric acids. Bidirectional sequencing of the GCDH gene revealed ten mutations, three of which were novel (Gln76Pro, Glu131Val, and Gly390Trp). The spectrum of mutations included eight missense mutations, a nonsense mutation, and a splice site mutation. Two mutations (Gln76Pro and Arg386Gln) were homozygous in two patients with parental consanguinity. All mutations were predicted to be disease causing by MutationTaster2. In conclusion, this is the first report of both clinical and molecular aspects of GA1 in Malaysian patients. Despite the lack of genotype and phenotype correlation, early diagnosis and timely treatment remained the most important determinant of patient outcome.
