Se reconoce que no existen reportes genéticos poblacionales de esta variante en Cuba, que permitan caracterizar los perfiles inmunogenéticos a nivel molecular, para su aplicación en estudios de asociación alélica.  Objetivo:  Describir las frecuencias génicas y genotípicas del polimorfismo VEGF (+405 G&gt;C) en la población cubana.  Material y Métodos:  Se realizó un estudio observacional, descriptivo, transversal, entre octubre de 2017 y marzo de 2018 en 162 neonatos cubanos, de ambos sexos y sanos, para el pesquisaje neonatal de enfermedades metabólicas, cuyas muestras biológicas se conservaban en el banco de ADN del Centro Nacional de Genética Médica. La caracterización molecular de los genotipos fue realizada mediante un PCR-ARMS. Se utilizó el software GENEPOP 4.4 y el paquete estadístico STATISTICA 8.0 para los cálculos de las frecuencias génicas y genotípicas.  Resultados:  La población no se ajustó al modelo de equilibrio de Hardy Weinberg para el gen evaluado. Las frecuencias génicas estimadas para el polimorfismo VEGF (+405 G&gt;C) fueron de 0,33 para el alelo G y de 0,67 para el alelo C. El cálculo de las frecuencias genotípicas resultó en 0,14, 0,37 y 0,49, para las variantes GG, GC y CC, respectivamente.  Conclusiones:  Las frecuencias alélicas VEGF.C fueron superiores a la del alelo VEGF.G, siendo el genotipo VEGF.GG el de menor representación en el conjunto estudiado.]]></p></abstract>

In its gene, +405G&gt;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&gt;C) polymorphism in the Cuban population.  Material and Methods:  A descriptive cross-sectional 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&gt; 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.]]></p></abstract>
