APOE Gene Associated with Cholesterol-Related Traits in the Hispanic Population.

ABSTRACT: Genetic variants in the apolipoprotein E (APOE) gene are associated with lipid metabolism and lipid-related traits in the non-Hispanic population. There have been limited studies regarding the association between the APOE gene and hypercholesterolemia in the Hispanic population; therefore, our aim for this study is to examine the APOE gene's associations with cholesterol level and its related phenotypes. The APOE gene consists of three different alleles, ε2, ε3, and ε4, with ε4 being associated with dementia and cardiovascular diseases. A total of 1,382 subjects were collected from the Texas Alzheimer's Research and Care Consortium (TARCC, N = 1320) and the Initial Study of Longevity and Dementia from the Rio Grande Valley (ISLD-RGV, N = 62). Questionnaires on demographics, medical history, and blood/saliva samples were collected and APOE genotypes were performed. We observed allele frequencies of the APOE ε3 (96.7%), ε4 (22.6%) and ε2 (6.8%) alleles, respectively. Multivariable logistic regression revealed a significant association between the APOE ε4 allele and hypercholesteremia (p = 1.8 × 10-4) in our studied Hispanic population. We prove for the first time, that the APOE ε4 allele increases the risk for hypercholesterol in Hispanics. Further research is needed to confirm and supports our current findings.

Project description:Background and aimsObesity is a growing public health concern in Bangladesh, which is influenced by a complex interplay of genetic and environmental factors. The genetic variant rs9939609 of the FTO (fat mass and obesity-associated) gene has been found to be associated with an increased risk for obesity, depending on the population studied. The purpose of this cross-sectional study is to examine the relationship between the FTO gene polymorphism (rs9939609) and lifestyle-related risk factors, and their impact on obesity-related traits and biochemical parameters in the Bangladeshi population.MethodsA total of 280 participants were enrolled in this study, comprising of 140 individuals with overweight and obesity (body mass index [BMI] ≥ 23.0) and 140 non-overweight healthy individuals (18.5 ≤ BMI ≥ 22.9). Demographic information, dietary behaviors, and physical activity-related data were collected using a structured questionnaire. Additionally, anthropometric assessments and measurements of biochemical parameters such as lipid profile and C-reactive protein were performed. The amplification refractory mutation system-polymerase chain reaction technique was used to identify single-nucleotide polymorphism in the FTO gene. Descriptive statistics, χ,2 and one-way ANOVA were performed to evaluate the relationships between independent and dependent variables.ResultsThe presence of rs9939609 was strongly associated with the obesity risk factors of increased BMI, cholesterol, triglycerides, and low-density lipoprotein. We also found a significant association (p < 0.05) of rs9939609 with overweight and obesity in codominant AA versus TT (odds ratio [OR] = 0.299, 95% CI: 0.129-0.695) and AA versus AT (OR = 2.273, 95% CI: 1.023-5.053), recessive TT versus AA+AT (OR = 5.154, 95% CI: 2.463-10.782), and overdominant AT versus AA+TT (OR = 0.244, 95% CI: 0.122-0.488) models.ConclusionFTO variant rs9939609 is significantly linked to obesity and an increased risk of hyperlipidemia in the Bangladeshi population. However, this association is intertwined with environmental factors such as diet and physical activity.
