From Genotype to Phenotype: Through Chromatin.

Area of Science:

• Genomics and Epigenetics
• Molecular Biology
• Disease Pathogenesis

Background:

• Sequencing technologies have advanced genetic disorder research, identifying mutations for rare and common diseases.
• Current limitations exist in linking mutations to causal genes and therapeutic targets, especially for mutations in regulatory genome regions.
• Many diseases, including neurodegenerative disorders, lack apparent genetic causes, necessitating complementary research approaches.

Purpose of the Study:

• To highlight the growing interest in epigenetic control as a complementary approach to genetics for understanding disease.
• To summarize recent studies linking large-scale epigenetic datasets to disease contexts and genotype-phenotype relationships.
• To review advancements in understanding epigenetic processes in disease development and progression.

Main Methods:

• Focus on DNA methylation and histone marks, driven by technological improvements and large epigenome consortia.
• Analysis of recent studies generating large-scale epigenetic datasets in disease contexts.
• Evaluation of methodologies enabling the establishment of causal relationships in epigenetics.

Main Results:

• Epigenetic data provides a more complete functional genomic map, complementing genetic information.
• Advances in DNA methylation and histone mark analysis are crucial for disease research.
• Methodological progress allows for establishing causal links between epigenetic modifications and disease.

Conclusions:

• Epigenetic research, particularly DNA methylation and histone modifications, is vital for understanding complex diseases.
• Future research should focus on addressing key issues in epigenetic analysis to advance therapeutic development.
• Establishing causal relationships through advanced methodologies is critical for future breakthroughs in disease etiology and treatment.
