Abstract Background SLC10A1 gene codes NTCP, a receptor through which the hepatitis B virus (HBV) gets access into hepatocytes – a stage of the viral cycle necessary for replication. Polymorphism variants of SLC10A1 play roles in HBV infection, viral clearance, treatment outcome, and complications, in diverse ethnic groups and countries. However, no such study has been conducted in the Ghanaian population, a country with HBV endemicity. Therefore, an exploratory study was conducted to investigate the presence of three (3) single nucleotide polymorphisms (SNPs) in the SLC10A1 gene (rs2296651, rs61745930, and rs4646287) and assessed the risk of HBV infection among the Ghanaian population. Method Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used to determine the Doxycycline HCl presence of the SNPs among 292 participants comprising 146 HBV infected persons as case-subjects and 146 HBV non-infected persons as control-subjects. Results The minor allele frequency (T) of rs2296651 was present in a significantly high proportion of cases compared with the control group (11.6% vs. 3.1%, enzyme (NEB, USA) and dissolved in 1.5?L of NEB buffer and 3.3?L of nuclease-free water, and incubated at 37 0 C for 11?min for the enzyme digestion of the PCR item. Likewise, 15?L from the PCR item was either put into 0.2?L of or 0.2?L of enzymes (NEB, USA) and dissolved in 1.5?L of NEB buffer and 3.3?L of nuclease-free drinking water and incubated in 60 0 C for 60?min (1?h) for the enzyme digestive function of either rs61745930 or rs4646287. Item visualizationThe digested fragments had been separated having a 2.5% EtBr- incorporated agarose gel at 100?V, 2A for 90?min, and using the Quick-Load crimson 100?bp DNA Ladder (NEB, USA) while the molecular marker (MM) and visualized less than UV trans-illuminator. The genotypes had been determined according to the band patterns/sizes and in comparison, to the molecular marker (MM) as shown in the supplementary figures. Figure S1, Figure S2 and Figure S3 show the gel bands for the SNP rs2296651, rs61745930, and rs4646287, respectively. Statistical analysis Results obtained were entered into the Statistical Package for the Social Sciences (SPSS), coded, and analyzed using Doxycycline HCl this SPSS (version 23.0). Frequencies were used to represent categorical data and compared using Chi-Square test analysis to compare the genotype and allele frequencies between the groups. Doxycycline HCl Skewed data were compared using the Man-Whitney Test. Normally distributed data were represented with mean??standard deviation and compared between groups using the T-test. To test for associations between HBV and every single SNP, logistic regression models were fitted, in which each SNP was presented as a predictor variable whose values were equal to the number of copies of the minor allele (0, 1, 2) in an additive model, or presence of at least one copy of the minor allele (0, 1) in a dominant model or presence of two copies of the minor allele (0, 1) in a recessive model. Sex, age and family history of HBV status were included as covariates in the fitted model. The structure of the model was represented as: Logit Alanine aminotransferase, Aspartate aminotransferase, Gamma-glutamyl transferase, Aspartate aminotransferase-to-platelet ratio index, fibrosis index based on four factors, RDW-to-platelet ratio, Hardy-Weinberg equation Hardy-Weinberg equation p-values, ?P-values represents the chi-square test to compare genotype frequency between FGF11 case-and control -subjects. mutant type, wild type, Highlighted values represent statistically significant values.
