[Research progress on genetic and epigenetic mechanisms in congenital heart disease]

Area of Science:

• Cardiology
• Genetics
• Developmental Biology

Background:

• Congenital heart disease (CHD) encompasses birth defects in heart and blood vessel development during embryogenesis.
• The etiology of CHD is complex, involving intricate genetic and epigenetic mechanisms.
• Current diagnostic and therapeutic strategies primarily utilize established genetic mechanisms like chromosome abnormalities and gene mutations.

Purpose of the Study:

• To review the intricate relationship between genetic and epigenetic modifications and the occurrence of CHD.
• To explore the roles of chromosomal abnormalities, gene mutations, copy number variations, and epigenetic modifications in CHD.
• To provide a foundation for advancing early diagnosis and individualized therapy for CHD.

Main Methods:

• Literature review and synthesis of existing research on CHD etiology.
• Analysis of genetic and epigenetic factors contributing to congenital heart defects.
• Examination of the clinical applications and research gaps in CHD diagnosis and treatment.

Main Results:

• Genetic factors such as chromosomal abnormalities and gene mutations are established contributors to CHD.
• Epigenetic modifications, including nucleic acid alterations and non-coding RNAs, are increasingly recognized for their role in CHD.
• Significant research is still needed to translate these genetic and epigenetic findings into clinical practice for CHD.

Conclusions:

• Genetic and epigenetic alterations are fundamental to the development of CHD.
• Further investigation into these mechanisms is crucial for developing novel diagnostic tools and personalized treatment strategies for CHD.
• This review highlights the potential for a deeper understanding of CHD etiology to revolutionize patient care.
