ABSTRACT

Introduction: The vascular endothelial growth factor (VEGF) is a protein involved in the proliferation and cell migration of the vascular endothelium. In its gene, +405G>C Polymorphism has been reported. There are no population genetic reports of this variant in Cuba that allow the characterization of immunogenetic profiles at a molecular level for its application to allelic association studies.
Objectives: To describe the genic and genotypic frequencies of the VEGF (+405 G>C) polymorphism in the Cuban population.
Material and Methods: A descriptive crosssectional observational study was carried out from October 2017 to March 2018 in 162 Cuban healthy newborns of both sexes for the neonatal screening for metabolic diseases, whose biological samples were conserved in the DNA bank of the National Center for Medical Genetics. The molecular characterization of the genotypes was carried out using a PCR-ARMS. The GENEPOP 4.4 software and the statistical software package STATISTICA 8.0 were used for the analysis of genic and genotypic frequencies.
Results: The population did not adjust to the Hardy-Weinberg equilibrium model for the gene evaluated. The estimated gene frequencies of VEGF +405 G> C polymorphism were 0.33 for the G allele and 0.67 for the C allele. The calculation of the genotypic frequencies resulted in 0.14, 0.37 and 0.49, for the variants GG, GC and CC, respectively.
Conclusions: The allelic frequencies of VEGF.C were higher than the frequencies of the VEGF.G allele, being the VEGF GG the least represented genotype in the group studied.
