Abstract
INTRODUCTION: Several studies have reported that the single nucleotide polymorphism rs693 of Apo lipoprotein B gene is associated with high levels of plasma lipids and high body mass index, which are risk factors for cardiovascular diseases. The distribution of this single nucleotide polymorphism and its association with the phenotype depend on the genetic background of each population.Entities:

| The present study was done to explore the association of SNP C/T7673 with dyslipidemia and overweight/obesity in a sample of the Colombian Caribbean population. The development of this study contributed to the field of potential biomarkers of risk of cardiovascular disease (CVD) in the Colombian population. |
|
|
| The distribution of SNP C/T7673 is in Hardy-Weinberg equilibrium in the studied population and the genotypic frequencies are similar to those reported by studies conducted in other Colombian populations and Latin American countries. Finally, it is suggested that the SNP C/T7673 does not influence the lipid profile and BMI in the studied population. |
|
|
| In Colombia, there are few studies on the possible association of polymorphism C/T7673 with dyslipidemias and overweight/obesity. These results contribute to new knowledge of biomarkers to identify the risk of CVD. |
| Este estudio se realizó con el propósito de explorar la asociación del SNP C/T7673 con dislipidemias y sobrepeso/obesidad en una muestra de la población del Caribe Colombiano. El desarrollo de este estudio contribuyó al campo de potenciales biomarcadores de riesgo de enfermedades cardiovasculares (ECV) en población colombiana. |
| La distribución del SNP C/T7673se encuentra en equilibrio de Hardy-Weinberg en la población de estudio y las frecuencias genotípicas son similares a las reportadas por estudios realizados en otras poblaciones colombianas y países latinoamericanos. Finalmente, se sugiere que el SNP C/T7673 no influye sobre los parámetros del perfil lipídico y el IMC en la población estudiada. |
| En Colombia, existen escasos estudios sobre la posible asociación del polimorfismo C/T7673con dislipidemias y sobrepeso/obesidad. Estos resultados aportan nuevo conocimiento sobre biomarcadores para la identificación de riesgo de ECV. |
