Functional modules, mutational load and human genetic disease.

Area of Science:

• Genomics
• Human Genetics
• Bioinformatics

Background:

• Advances in sequencing technology generate vast amounts of human genetic data.
• Whole exome and whole-genome resequencing are poised to replace targeted approaches for gene discovery and clinical testing.
• Interpreting the functional impact of genetic variations, both common and rare, presents a significant challenge.

Purpose of the Study:

• To discuss the challenges in assigning mutation functionality.
• To explore functional modularization of the human genome using examples like ciliopathies, cohesinopathies, and channelopathies.
• To highlight the need for physiologically relevant assays to test allele functionality.

Main Methods:

• Review of current challenges in mutation interpretation.
• Case studies of ciliopathies, cohesinopathies, and channelopathies.
• Conceptual framework for functional modularization of the genome.

Main Results:

• Assigning mutation functionality within the context of genomic variation is complex.
• Functional modularization offers a potential strategy to organize and interpret genomic data.
• Development of relevant assays is crucial for validating allele function.

Conclusions:

• Functional modularization and validated allele assays are essential for advancing disease architecture understanding.
• These approaches will enable the effective use of genome-wide sequence data for individual diagnosis and phenotypic prediction.
• This work addresses a critical bottleneck in translating genomic data into clinical applications.
