Abstract
Background: Single nucleotide polymorphism (SNP) variants of the uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) gene have been studied as an important factor in neonatal hyperbilirubinemia (jaundice) severity. Specific ethnicities, including Asians, have certain SNPs that appear more frequently than others. Aim: To identify the most common SNPs in Indonesian neonates and their association with the severity of neonatal hyperbilirubinemia. Methods: Eighty-eight inborn and outborn jaundiced infants from three different hospitals (Bengkulu, Jakarta, Biak Papua) across Indonesia were enrolled in this cross-sectional study and their peak total serum bilirubin (TSB) levels assessed. SNP variant analyses of the TATAA box, promoter, and exon 1 regions of UGT1A1 gene from 78 of the 88 infants were carried out using the SNaPshotR Multiplex Polymerase Chain Reaction (PCR) System followed by DNA sequencing. Results: We detected SNP variants UGT1A1 * 28, UGT1A1 * 60, UGT1A1 * 93, and UGT1A1 * 6 in our population. Mean total serum bilirubin (TSB) was 14.59 ± 5.57 mg/dL. Bivariate analyses using delivery location, gestational age, birth weight, mother's age, and ethnicity were shown to be associated with moderate-to-severe hyperbilirubinemia (p < 0.05). None of the four SNPs appeared to be associated with moderate-to-severe hyperbilirubinemia. In multivariate analysis, however, only the "other ethnic group" (e.g., Chinese, Bengkulu, Papua, Bima) category showed an association with moderate-to-severe hyperbilirubinemia, with an odds ratio of 6.49 (95% CI 1.01-41.67; p < 0.05). Conclusions: We found that the UGT1A1 * 60 is the most common SNP detected in neonates with hyperbilirubinemia in the Indonesian population. Interestingly, in Indonesia, UGT1A1 polymorphisms do not appear to be associated with differences in the severity of hyperbilirubinemia.

Abstract
Objective The genetic involvement in unconjugated neonatal hyperbilirubinemia has been extensively studied. Despite the high incidence of hyperbilirubinemia in Indonesia, studies are lacking. The objective of this study is to elucidate the role of polymorphism in the UGT1A1 in Neonatal Hyperbilirubinemia in Bengkulu, Indonesia. Results There were 41 neonates enrolled in the study; 30 had a total serum bilirubin level ≥ 15 mg/dL (hyperbilirubinemia neonates) while 11 has < 15 mg/dL (control neonates). Genetic mutations in Exon 1, UGT1A1*6 (c211g > a) and one in promoter region, UGT1A1*60 (c3279t > g) were determined by polymerase chain reaction–restriction fragment length polymorphism. We found 18 (60%) mutation in exon 1 in hyperbilirubinemia group and 7 (64%) in the control group with an identical allele frequency of 0.3 in both groups. We found heterozygous UGT1A1*60 4 times (13.3%) and homozygous 26 times (86.7%) in the hyperbilirubinemia group, with an identical allele frequency of 0.935 in hyperbilirubinemia and 1 in control group. This study supports the involvement of genetic factors in the development of unconjugated hyperbilirubinemia in Bengkulu population.

UGT1A1 Genetic Variations and a Haplotype Associated with Neonatal Hyperbilirubinemia in Indonesian Population. BIOMED RESEARCH INTERNATIONAL 2018; 2018:9425843. [PMID: 29607327 PMCID: PMC5828093 DOI: 10.1155/2018/9425843] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/10/2017] [Accepted: 12/04/2017] [Indexed: 12/30/2022]
Abstract
Neonatal hyperbilirubinemia (NH) is a common finding in newborn babies in Indonesia. Common and rare variants of UGT1A1 have been known to contribute to NH etiology. This study aims to identify UGT1A1 genetic variation and haplotype associated with NH in Indonesian population. DNA was isolated from 116 cases and 115 controls and a targeted-deep sequencing approach was performed on the promoter, UTRs, and exonic regions of UGT1A1. Determining association of common variants and haplotype analysis were performed using PLINK and Haploview. Ten and 4 rare variants were identified in cases and controls, respectively. The UGT1A1 rare variants frequency in cases (5.17%) was higher than that in controls (1.7%). Four of those rare variants in cases (p.Ala61Thr, p.His300Arg, p.Lys407Asn, and p.Tyr514Asn) and three in controls (p.Tyr79X, p.Ala346Val, and p.Thr412Ser) are novel variants. The frequencies of p.Gly71Arg, p.Pro229Gln, and TA7 common variants were not significantly different between cases and controls. A haplotype, consisting of 3 major alleles of 3′ UTRs common variants (rs8330C>G, rs10929303C>T, and rs1042640C>G), was associated with NH incidence (p = 0.025) in this population. Using targeted-deep sequencing and haplotype analysis, we identified novel UGT1A1 rare variants and disease-associated haplotype in NH in Indonesian population.

Abstract
Expanding the scope of pharmacogenomic research by including multiple global populations is integral to building robust evidence for its clinical translation. Deep whole-genome sequencing of diverse ethnic populations provides a unique opportunity to study rare and common pharmacogenomic markers that often vary in frequency across populations. In this study, we aim to build a diverse map of pharmacogenetic variants in South East Asian (SEA) Malay population using deep whole-genome sequences of 100 healthy SEA Malay individuals. We investigated the allelic diversity of potentially deleterious pharmacogenomic variants in SEA Malay population. Our analysis revealed 227 common and 466 rare potentially functional single nucleotide variants (SNVs) in 437 pharmacogenomic genes involved in drug metabolism, transport and target genes, including 74 novel variants. This study has created one of the most comprehensive maps of pharmacogenetic markers in any population from whole genomes and will hugely benefit pharmacogenomic investigations and drug dosage recommendations in SEA Malays.

Abstract
Background The results of studies on association between the polymorphisms in the coding region and the promoter of uridine diphosphateglucuronosyl transferase 1A1 (UGT1A1) and neonatal hyperbilirubinemia are controversial. This study aimed to determine whether the UGT1A1 gene polymorphisms of Gly71Arg and TATA promoter were significant risk factors associated with neonatal hyperbilirubinemia. Material/Methods The PubMed, Cochrane Library, and Embase databases were searched for papers that describe the association between UGT1A1 polymorphisms and neonatal hyperbilirubinemia. Summary odds ratios and 95% confidence intervals (CI) were estimated based on a fixed-effects model or random-effects model, depending on the absence or presence of significant heterogeneity. Results A total of 32 eligible studies and 6520 participants were identified. Among them, 24 studies focused on the association of neonatal hyperbilirubinemia with UGT1A1 Gly71Arg polymorphisms, and a significant difference was found for the comparison of AA vs. AG+GG (OR=3.47, 95% CI=2.29–5.28, P<0.0001). We included 19 studies on the association of neonatal hyperbilirubinemia with UGT1A1 TATA promoter polymorphism, which also found a statistically significant difference between 7/7 and 6/7 + 6/6 (OR=2.24, 95% CI=1.29–3.92, P=0.004). Conclusions This meta-analysis demonstrated that UGT1A1 polymorphisms (Gly71Arg and TATA promoter) significantly increase the risk of neonatal hyperbilirubinemia.

Abstract
BACKGROUND AND AIM The pathogenesis of neonatal hyperbilirubinemia hasn't been completely defined in Gloucose-6-Phosphate Dehydrogenase (G6PD) deficient newborns. The aim of this study was to detect the relationship between Gilbert's syndrome and hyperbilirubinemia in Gloucose-6-Phosphate Dehydrogenase (G6PD) deficient neonates. MATERIALS AND METHODS This case-control study was conducted in Amirkola pediatrics teaching hospital, Babol, Iran. A total number of one hundred four infants were included in the study (51 infants with neonatal jaundice and Gloucose-6-Phosphate Dehydrogenase (G6PD) deficiency admitted to phototherapy or transfusion were selected as the case group and 53 infants with Gloucose-6-Phosphate Dehydrogenase (G6PD) deficiency admitted for other reasons than jaundice were selected as the control group). Exclusion criteria were ABO or Rh incompatibility or other reasons that made Coombs test positive, sepsis, hepatosplenomegaly, metabolic diseases, medical treatment and phototherapy. The promoter and coding regions of Uridine diphosphate Glucuronosyl Transferase 1A1 (UGT1A1) of genomic DNA were amplified by polymerase chain reaction (PCR) isolated from leukocytes. We used chi-square test and t-test to compare cases and controls. RESULTS Distribution of Gilbert genome was not significantly different between the two groups; among cases, 33.3% were homozygote, 35.3% heterozygote, and 31.4% normal. Among controls, 22.6% were homozygote, 34% heterozygote, and 43.4% normal (p-value=xxx). Hyperbilirubinemia family history didn't differ significantly between these two groups. CONCLUSIONS We showed that in Gloucose-6-Phosphate Dehydrogenase (G6PD) deficient neonates, there was no significant association between Gilbert's syndrome (promoter polymorphism) and hyperbilirubinemia.

Abstract
Drug lag, recently discussed extensively in Japan, can be divided into two phases: clinical development time and application review time. The former factor is still an important problem that might be improved by promoting multi-regional clinical trials and considering the results from other similar populations with Japanese, such as Koreans and Chinese. In this review, we compare the allelic or genotype frequencies of 30 relatively common functional alleles mainly between Eastern Asians and Europeans as well as among 3 major populations in Eastern Asian countries, Japan, Korea, and China, in 12 pharmacokinetics (PK)/pharmacodynamics (PD)-related genes; CYP2C9 (*2 and *3), CYP2C19 (*2, *3 and *17), 13 CYP2D6 haplotypes including *4, *5 and *10, CYP3A5 (*3), UGT1A1 (*28 and *6), NAT2 (*5, *6 and *7), GSTM1 and GSTT1 null genotypes, SLCO1B1 521T>C, ABCG2 421C>A, and HLA-A*31:01 and HLA-B*58:01. In this review, differences in allele frequencies (AFs) or genotype frequencies (GFs) less than 0.1 (in the cases of highest AF (GF) ≥0.1) or less than 0.05 (in the cases of lowest AF (GF) <0.1) were regarded as similar. Between Eastern Asians and Europeans, AFs (or GFs) are regarded as being different for many alleles such as CYP2C9 (*2), CYP2C19 (*2, *3 and *17), CYP2D6 (*4 and *10), CYP3A5 (*3), UGT1A1 (*28 and *6), NAT2 (*5*7), GSTT1 null and ABCG2 421C>A. Among the 3 Eastern Asian populations, however, only AFs of CYP2C19*3, CYP2D6*10, HLA-A*31:01 and HLA-B*58:01 are regarded as dissimilar. For CYP2C19*3, the total functional impact on CYP2C19 could be small if the frequencies of the two null alleles CYP2C19*2 and *3 are combined. Regarding CYP2D6*10, frequency difference over 0.1 is observed only between Japanese and Chinese (0.147). Although environmental factors should be considered for PK/PD differences, we could propose that among Japan, Korea, and China, genetic differences are very small for the analyzed common PK-related gene polymorphisms. On the other hand, AFs of the two HLA alleles important for cutaneous adverse drug reactions are diverse even among Eastern Asians and thus should be taken into account.

Abstract
BACKGROUND Recent reports have suggested that genetic factors, including mutations in the coding region or promoter of uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) may increase the risk of development of neonatal hyperbilirubinemia, but the relationship has not been evaluated on systematic review or meta-analysis. METHODS A meta-analysis of observational studies reporting effect estimates and 95% confidence intervals (95%CI) was conducted on the association between UGT1A1 polymorphisms and neonatal hyperbilirubinemia. RESULTS A total of 27 eligible studies were identified. In total, 17 studies focused on the association of neonatal hyperbilirubinemia with UGT1A1 Gly71Arg polymorphisms, which indicated that these polymorphisms were associated with an increased risk of neonatal hyperbilirubinemia (A/A+G/A vs G/G: odds ratio [OR], 2.70; P= 0.00; 95%CI: 2.22-3.29; I(2) = 0.0%; P(heterogeneity) = 0.55). Subgroup analyses by ethnicity validated this correlation in Asian, but not in Caucasian, populations (OR, 1.74; P= 0.10; 95%CI: 0.90-3.35; I(2) = 0.00%; P(heterogeneity) = 0.67). Furthermore, 18 studies focused on the association of neonatal hyperbilirubinemia with UGT1A1 TATA promoter polymorphisms. These studies concluded that TATA promoter variants were not associated with an increased risk of neonatal hyperbilirubinemia (7/7 + 6/7 vs 6/6: OR, 1.13; P= 0.23; 95%CI: 0.93-1.37; I(2) = 80.0%; P(heterogeneity) = 0.00). CONCLUSION UGT1A1 Gly71Arg polymorphisms are a risk factor for developing neonatal hyperbilirubinemia in Asian, but not Caucasian, subjects. UGT1A1 TATA promoter polymorphisms were not associated with an increased risk of neonatal hyperbilirubinemia in Asian subjects, but results from the Caucasian population were conflicting and require further epidemiological investigation.

Abstract
AIM To determine whether the UDP-glucuronosyltransferase 1A1 gene (UGT1A1) Gly71Arg (211G>A) mutation is associated with neonatal hyperbilirubinemia. METHODS The study consisted of two parts. The case-control study included 112 hyperbilirubinemic infants and 105 control subjects from the Fifth People's Hospital of Shenzhen. Polymerase chain reaction, restriction fragment length polymorphisms and agarose gel electrophoresis techniques were used to detect the UGT1A1 211G>A mutation. Meta-analyses was performed to assess the association between neonatal hyperbilirubinemia and UGT1A1 211G>A. RESULTS Our case-control study revealed that the likelihood of developing neonatal hyperbilirubinemia was 2.65 times higher in the infants with the A allele in the UGT1A1 211G>A than in the infants with the G allele (95% CI, 1.60-4.39). Meta-analyses (including data from our study) revealed that UGT1A1 211G>A is associated with an increased risk of neonatal hyperbilirubinemia [odds ratio (OR), 2.37; 95% CI, 2.05-2.74]. In the subgroup analyses based on ethnicity, significantly elevated risks were found in Asian populations (OR, 2.45; 95% CI, 2.10-2.84), but no significant associations were present in Caucasian populations (OR, 1.54; 95% CI, 0.87-2.75). CONCLUSION The UGT1A1 211G>A mutation is associated with neonatal hyperbilirubinemia in Asians, but not in Caucasians.

Abstract
The uridine diphosphoglucuronate-glucuronosyltransferase 1A1 (UGT1A1) gene encodes the enzyme responsible for bilirubin glucuronidation. To evaluate the contribution of UGT1A1 promoter mutations to neonatal jaundice, we determined the genotypes of c.-3279T>G, c.-3156G>A, and A(TA)7TAA in Malay infants with neonatal jaundice (patients) and in infants without neonatal jaundice (controls). In our population study, only c.-3279T>G was associated with neonatal jaundice. The genotype distributions between both groups were significantly different (p = 0.003): the frequency of homozygosity for c.-3279G was much higher in patients than those in controls. Allele frequency of c.-3279G was significantly higher in patients than those in controls (p = 0.006). We then investigated changes in transcriptional activity because of c.-3279T>G. Luciferase reporter assay in HepG2 cells demonstrated that transcriptional activity of the c.-3279G allele was significantly lower than that of the c.-3279T allele in both the absence and presence of bilirubin. Luciferase reporter assay in COS-7 cells elucidated that c.-3279T>G modified the synergistic effects of the nuclear factors associated with transcriptional machinery. In conclusion, the c.-3279T>G mutation in the UGT1A1 promoter is a genetic risk factor for neonatal jaundice.

Abstract
Variants within the human UGT1A1 gene are associated with irinotecan induced severely adverse reactions and hyperbilirubinemia. Intra-ethnic differences in the genetic variation and haplotypes of UGT1A1 gene have been analyzed in the present study. Relationship between the concentrations of total serum bilirubin (T-bil) and haplotype structure of UGT1A1 in healthy people were also evaluated. We genotyped five functional polymorphisms including -3279T>G and -3156G>A in the enhancer region, (TA)6>7 in the TATA box, and 211G>A (G71R), 686C>A (P229Q) in the exon1 region of UGT1A1 in three groups of healthy Chinese ethnic populations, consisting of 264 subjects of She origin, 539 of Han origin and 273 of Dong origin. The distribution of -3279T>G, (TA)6>7, 211G>A of UGT1A1 differed greatly as between the three ethnic groups. All of six haplotypes differed considerably between at least two of the three groups, which highlighted the need to analyze clinically irinotecan toxicity relevant SNPs and haplotypes in a variety of different racial groups within the Chinese population. Total bilirubin concentration in homozygous carriers of the -3279G and (TA)7 allele were significantly higher than those in heterozygous carriers or homozygous carriers of wild-type alleles. Carriers of the variant haplotypes (-3279G; -3156A; (TA)7; 211G; 686C) had higher serum T-Bil concentrations compared with the other groups. Our results indicate that heterogeneity among different ethnic populations is possibly the result of microevolution and is relevant to studies into the effect of tailored drug treatment.

Abstract
Mutations in the gene encoding UDP-glucuronosyltransferase 1A1 (UGT1A1) may reduce the glucuronidation of estradiol, bilirubin, etc. In the present study, we used a liquid chromatography-tandem mass spectrometry (LC/MS/MS) method to assay the activities of recombinant mutated UGT1A1 toward 17beta-estradiol (E2), by determining its glucuronide (E2G) content. Direct evidence for glucuronide formation was provided by E2G-specific ion peaks. The UGT1A1 activities of G71R (exon 1), F83L (exon 1), I322V (exon 2) and G493R (exon 5) mutants were 24, 30, 18 and 0.6% of the normal UGT1A1 activity, respectively. In conclusion, our study showed that LC/MS/MS enabled accurate evaluation of the effects of mutations on recombinant UGT1A1 activity towards E2.

Abstract
BACKGROUND Gilbert syndrome is caused by defects in the uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) gene. These mutations differ among different populations and many of them have been found to be genetic risk factors for the development of neonatal jaundice. OBJECTIVES The objective was to determine the frequencies of the following mutations in the UGT1A1 gene: A(TA)7TAA (the most common cause of Gilbert syndrome in Caucasians), G71R (more common in the Japanese and Taiwanese population), and G493R (described in a homozygous Malay woman with Crigler-Najjar syndrome type 2) in a group of Malaysian babies with hyperbilirubinemia and a group of normal controls. METHODS The GeneScan fragment analysis was used to detect the A(TA)7TAA variant. Mutation screening of both G71R and G493R was performed using denaturing high performance liquid chromatography. RESULTS Fourteen out of fifty-five neonates with hyperbilirubinemia (25%) carried the A(TA)7TAA mutation (10 heterozygous, 4 homozygous). Seven out of fifty controls (14%) carried this mutation (6 heterozygous, 1 homozygous). The allelic frequencies for hyperbilirubinemia and control patients were 16 and 8%, respectively (p=0.20). Heterozygosity for the G71R mutation was almost equal among both groups (5.5% for hyperbilirubinemia patients and 6.0% for controls; p=0.61). One subject (1.8%) in the hyperbilirubinemia group and none of the controls were heterozygous for the G493R mutation (p=0.476). CONCLUSIONS The A(TA)7TAA seems more common than the G71R and G493R mutations in the Malaysian population.
