Application of high-throughput sequencing for studying genomic variations in congenital heart disease

Area of Science:

• Genetics
• Developmental Biology
• Medical Research

Background:

• Congenital heart diseases (CHD) are the most frequent birth defects, often resulting from complex genetic and environmental interactions.
• While numerous causative mutations are known, the precise genetic origins of many cardiac malformations remain elusive.
• Advancements in high-throughput sequencing offer powerful new tools to investigate the genetic underpinnings of CHD.

Purpose of the Study:

• To provide a comprehensive roadmap for designing and analyzing high-throughput sequencing studies for CHD.
• To discuss strategies for identifying disease-related genomic variations and prioritizing candidate genes.
• To review existing control datasets and current applications of next-generation sequencing (NGS) in CHD research.

Main Methods:

• Discussion of the three major next-generation sequencing (NGS) platforms, detailing their strengths and weaknesses.
• Explanation of various filtering steps and gene prioritization techniques for analyzing sequencing data.
• Summary of available NGS-based control datasets relevant to CHD studies.

Main Results:

• High-throughput sequencing technologies present significant opportunities for advancing CHD genetic research.
• The review details methodologies applicable to CHD and other complex genetic diseases.
• Current studies demonstrate the utility of NGS in uncovering the complex genetic architecture of CHD.

Conclusions:

• Next-generation sequencing (NGS) is a transformative technology for unraveling the genetic basis of congenital heart diseases.
• The outlined roadmap provides a framework for effective study design and data analysis in complex disease genetics.
• Continued application of NGS will significantly enhance our understanding of CHD etiology.
