Genome Science
Functional Genomics
Perturbation screens and assays that connect sequence variation to molecular function.
Scientific context
Understanding the field
CRISPR-based screens, massively parallel reporter assays and deep mutational scanning are used to generate functional evidence for variant interpretation.
Functional genomics tests how genes and regulatory elements influence molecular and cellular phenotypes. Systematic perturbation helps move from statistical association toward experimentally supported mechanisms.
Central questions
- Which elements regulate a gene in a defined cell state?
- What functional effect does a specific variant produce?
Methodological framework
- CRISPR perturbation and pooled screening
- Reporter assays and mutational scanning
- Transcriptomic and proteomic readouts
Relevance
Scientific and clinical value
Functional evidence can prioritise candidate genes, clarify regulatory mechanisms and strengthen variant assessment when assays accurately model the relevant biological context.
Limits and responsibility
Cell models, dosage and assay endpoints may not reproduce physiology. Experimental effects require replication, appropriate controls and cautious translation to organismal or clinical meaning.
