Resumen

El intervalo electrocardiográfico PR mide la despolarización y conducción auriculoventricular, y el intervalo PR anormal es un factor de riesgo para la fibrilación auricular y el bloqueo cardíaco. Nuestro estudio de asociación del genoma de más de 92.000 individuos de ascendencia europea identifica 44 loci de intervalo PR (34 novela). El examen de estos loci revela procesos biológicos conocidos y aún no reportados involucrados en la actividad eléctrica auricular cardíaca. Los genes de estos loci están sobrerrepresentados en los procesos de las enfermedades cardíacas, incluyendo el bloqueo cardíaco y la fibrilación auricular. Las variantes en más de la mitad de los 44 loci se asociaron con niveles de expresión auricular o de transcripción sanguínea, o se encontraban en un desequilibrio de alta vinculación con variantes de missense. Se identificaron seis loci adicionales mediante el metanálisis de ~105.000 individuos de ascendencia africana y europea y/o mediante análisis pleiotrópicos que combinaban el intervalo de RP con la frecuencia cardíaca, el intervalo de QRS y la fibrilación auricular. Estos hallazgos implican las vías de desarrollo e identifican los factores de transcripción, los genes del canal iónico y las proteínas de señalización celular/juntura celular en la conducción auriculoventricular, identificando posibles dianas para el desarrollo de fármacos.

N2 - Electrocardiographic PR interval measures atrio-ventricular depolarization and conduction, and abnormal PR interval is a risk factor for atrial fibrillation and heart block. Our genome-wide association study of over 92,000 European-descent individuals identifies 44 PR interval loci (34 novel). Examination of these loci reveals known and previously not-yet-reported biological processes involved in cardiac atrial electrical activity. Genes in these loci are over-represented in cardiac disease processes including heart block and atrial fibrillation. Variants in over half of the 44 loci were associated with atrial or blood transcript expression levels, or were in high linkage disequilibrium with missense variants. Six additional loci were identified either by meta-analysis of ~105,000 African and European-descent individuals and/or by pleiotropic analyses combining PR interval with heart rate, QRS interval, and atrial fibrillation. These findings implicate developmental pathways, and identify transcription factors, ion-channel genes, and cell-junction/cell-signaling proteins in atrio-ventricular conduction, identifying potential targets for drug development.
