¿Existe una asociación entre polimorfismos de inserción/supresión - 2549 en la región promotora del gen que codifica la vegfa como factor de riesgo y el descargo espontáneo idiopático recurrente en una muestra de mujeres jordanas? / Is there an association between - 2549 Insertion/ Deletion Polymorphisms in the Promotor Region of the Gene Encoding for VEGFA as a Risk Factor and the Idiopathic Recurrent Spontaneous Miscarriage in a sample of Jordanian Women?

RESUMEN
Antecedentes al menos el 50% de los casos de aborto espontáneo recurrente son etiológicamente idiopáticos. Recientemente se han propuesto varios polimorfismos genéticos como factores de riesgo de susceptibilidad a la pérdida del embarazo.

Objetivo:

El objetivo del presente estudio de casos y controles es establecer la asociación entre los polimorfismos funcionales −2549 I / D en la región promotora del gen del factor de crecimiento endotelial vascular A (VEGFA) y el aborto espontáneo recurrente idiopático (IRSM) en una muestra de las mujeres jordanas. Sujetos y

métodos:

Se reclutaron 328 sujetos, 103 y 98 mujeres con IRSM primario y secundario, respectivamente, se seleccionaron 127 mujeres normales como grupo de control. Se aisló ADN genómico de una muestra de sangre extraída de cada participante, luego, se genotipificaron los polimorfismos I / D -2549 del gen VEGFA mediante la reacción en cadena de la polimerasa (PCR).

Resultados:

Los resultados obtenidos revelaron que el polimorfismo ID y el alelo D de VEGFA -2549 polimorfismos I / D tienen las frecuencias más altas en pacientes IRSM tanto primario como secundario, sin diferencia significativa entre los tres grupos en cuanto a polimorfismos y frecuencias alélicas, pacientes con DD + ID Los modelos genéticos tienen una asociación positiva con un alto riesgo de IRSM versus el modelo II, y los pacientes con alelo D son más propensos a tener IRSM que los que tienen el alelo I, no hay diferencia significativa en la asociación de polimorfismos VEGFA -2549 I / D con IRSM en los tres modelos genéticos de los pacientes con IRSM primario y secundario.

Conclusión:

los pacientes con modelo genético ID de polimorfismos I / D -2549 en la región promotora del gen VEGFA y el alelo D tienen mayor riesgo de IRSM
ABSTRACT

Background:

At least 50% of the cases of recurrent spontaneous miscarriage are aetiologically idiopathic. Recently various genetic polymorphisms have been proposed as susceptibility risk factors for pregnancy loss.

Objective:

The aim of the present case control study is to establish the association between the functional −2549 I/D polymorphisms in the promoter region of the vascular endothelial growth factor A (VEGFA) gene and idiopathic recurrent spontaneous miscarriage (IRSM) in a sample of Jordanian women. Subjects and

methods:

328 subjects were recruited, 103 and 98 women with primary and secondary IRSM, respectively, 127 normal women were selected as a control group. Genomic DNA was isolated from a blood sample withdrawn from each participant, then, -2549 I/D polymorphisms of VEGFA gene were genotyped by Polymerase Chain Reaction (PCR).

Results:

The obtained results revealed that ID polymorphism and D allele of VEGFA -2549 I/D polymorphisms have the highest frequencies in both primary and secondary IRSM patients, no significant difference between the three groups regarding polymorphisms and allele frequencies, patients with DD+ID genetic models have positive association with high risk of IRSM versus II model, and patients with D allele are more liable to have IRSM than those having I allele, no significant difference in the association of VEGFA -2549 I/D polymorphisms with IRSM in the three genetic models of the primary and secondary IRSM patients.

Conclusion:

patients with ID genetic model of -2549 I/D polymorphisms in the VEGFA gene's promotor region and D allele have higher risk for IRSM.
