Essential Genes

The IMPC is seeking to identify and characterize genes that are essential for organism viability. We attempt to ascertain genes that are critical for development and health and, ultimately, associated to human disease.

Identifying which genes are linked to a rare disease is one of the most difficult challenges geneticists face. The IMPC categorizes genes into essentiality bins (FUSIL bins) by cross comparing viability and phenotyping data from knockout IMPC mice with human cell essentiality (Achilles/Avana) scores from the Cancer Dependency map. These bins range from more to less essential. Thus, genes can be categorised on how essential they are for supporting life and the likelihood they are associated with de novo genetic disorders. In this portal, we present integrated views of viability data to help researchers explore the full genetic spectrum of essentiality and aid unvailing yet unknown genetic associations to human disease.

IMPC and human cell viability data

FUSIL scores available for 3783 human genes

  • CL- Cellular Essential
  • DL- Developmental Essential
  • SV- Subviable
  • VP- Viable with significant phenotype(s) detected
  • VN- Viable with no signficant phenotype detected

DL genes are enriched for de novo genetic diseases. Check the IMPC paper on gene essentiality in Nature Communications 2020.
