Identification of Genetic Basis of Atrioventricular Conduction Defects: From Congenital Forms to Degenerative Forms

Brief description of study

Identification of genes involved in congenital atrioventricular block and progressive Cardiac Conduction Disease.

Detailed Study Description

Atrioventricular blocks are a heterogenous group of diseases involving children with congenital atrioventricular block (CAB) and more frequently elderly patients affected by progressive Cardiac Conduction Disease (PCCD).

The aim of the study is to uncover the genetic model, likely more complex than previously appreciated, and characterize the gene expression remodelling leading to high degree of conduction defect.

The recent technological developments in genomics coupled to the availability of large and highly characterized biobanks of patients have now set the stage:

  1. To identify rare genetic variants/new genes contributing to CAB and PCCD by exome sequencing on familial form suspected to impact strongly the phenotype
  2. To identify common genetic variants modulating the risk of developing (severe) PCCD by GWAS
  3. To estimate the prevalence and relevance of genes uncovered by TASK#1, #2 in large patient sets (PCCD and CAB) by NGS.

Clinical Study Identifier: NCT02881671
