IMPC - International Mouse Phenotyping Consortium

Rare Disease Day 2026 | IMPC | International Mouse Phenotyping Consortium Rare diseases are defined by their low prevalence — often fewer than 1 in 2,000 people — yet collectively affect hundreds of millions worldwide. These conditions are frequently genetic, complex, and under‑researched, with many patients facing long diagnostic journeys and limited treatment options. Rare Disease Day, observed every year on 28 February, raises global awareness of rare conditions and […]

On #RareDiseaseDay, we want to celebrate the contributions of our member laboratories to rare disease research through systematic mouse genetics, including through collaboration with the European Joint Programme on Rare Diseases.

Inclusion in the BIA means that these images are now available to the wider image analysis community as reference datasets for AI method development. Each submission includes experimental protocols, instrument details, and gene information linked to mutant lines to ensure data is FAIR.

IMPC Images Now in Long-Term Image Archive | IMPC | International Mouse Phenotyping Consortium The IMPC has collected over 850,000 images (DR23, April 2025) derived from systematic phenotyping of wild-type and mutant mouse lines. The collection spans multiple imaging modalities, including X-Ray, slit lamp eye imaging, Optical Coherence Tomography, light microscopy, microCT reconstructions of embryos, and histological sections, and has contributed to identification of candidate mouse models for more […]

By analysing optical sections from 2987 embryos from 484 homozygous lines, they identified 44 novel genes implicated in palatogenesis. These findings will help us better understand rare human congenital disorders that involve craniofacial defects such as cleft palate.

Identification of novel genes regulating the development of the palate:
Check out this paper from Ashwin Bhaskar and Sophie Astrof of Rutgers University where they use IMPC-generated 3D image data sets to screen for genes involved in palatogenesis

Endothelial RNF20 suppresses endothelial-to-mesenchymal transition and safeguards physiological angiocrine signaling to prevent congenital heart disease Heart morphogenesis and function rely on intricate communication among distinct cardiac cell types. How their co-development and crosstalk are coordinated is largely unexplored. Our study unveils key functions of the histone H2B ubiquitin (H2Bub1) ...

Check out this new paper that shows that RNF20 maintains endothelial identity, regulates TGF-β signaling, and promotes angiocrine Nrg1 expression, ensuring normal cardiomyocyte growth and function.

IMPC survey: Completing the catalogue of mammalian gene function and defining future priorities IMPC is currently evaluating its future production and phenotyping priorities. To date, IMPC has focused on protein coding genes with human orthologs and little to no functional annotation, also referred to as “dark genes”. To date, the International Mouse Phenotyping Consortium- IMPC [which includes the NIH-funded Knockout Mouse Phenotyping Program (KOMP2)] has produced knockout mouse lines for 11,208 unique genes and conducted comprehensive phenotyping on 9,774 knockout lines, representing 9,073 genes. All data is accessible at www.mousephenotype.org and mice are available to order from public mouse repositories [e.g., Mutant Mouse Resource and Research Center (MMRRC)]. The purpose of this survey is to ascertain your level of interest and enthusiasm for IMPC to continue its production and phenotyping of knockout mouse lines for the remaining human orthologous genes in the mouse genome. In addition, this survey seeks your input on the scientific value of IMPC producing and phenotyping allele types other than knockouts. As a representative of your field of research, please consider and answer the following 9 questions…think broadly! Thank you for participating in this brief 10 minute survey.

There's still time to complete our survey and help us define our future priorities!

IMPC’s Impact on Biomedical Research The IMPC has significantly impacted the advancement in biomedical research by systematically generating and phenotyping knockout mice for nearly every protein-coding gene. The data IMPC provided has led to major discoveries in gene function, enabled the development of new disease models, and provided an open-access resource that supports translational research and precision medicine.

🧬 The IMPC is unlocking gene function at scale powering discovery in translational research across disciplines.

🎥 Dr. Sabine Hölter-Koch explains the impact in this video: bit.ly/IMPCImpact
