The Mouse Genetics Project (MGP) is a large-scale
mutant
In biology, and especially in genetics, a mutant is an organism or a new genetic character arising or resulting from an instance of mutation, which is generally an alteration of the DNA sequence of the genome or chromosome of an organism. It ...

C57BL/6, often referred to as "C57 black 6", "C57" or "black 6", is a common inbred strain of laboratory mouse.
It is the most widely used "genetic background" for genetically modified mice for use as models of human disease. They are the most wid ...

The pipeline collects many measurements of viability, fertility, body weight, infection, hearing, morphology, haematology, behaviour, blood chemistry and immunity and compares them to
wild type controls using a statistical

As of July 2013, the MGP reports having over 900 mutant lines openly available to the international research community,
and have "substantively complete" analysis for over 650 mutant lines,
[ of which over 75 per cent have at least one abnormal phenotype.] Among these are new discoveries of genes implicated in disease, including finding:
*Mutation of SLX4
SLX4 (also known as BTBD12 and FANCP) is a protein involved in DNA repair, where it has important roles in the final steps of homologous recombination. Mutations in the gene are associated with the disease Fanconi anemia.
The version of SLX4 pres ...

Fanconi anaemia (FA) is a rare genetic disease resulting in impaired response to DNA damage. Although it is a very rare disorder, study of this and other bone marrow failure syndromes has improved scientific understanding of the mechanisms of nor ...

* Mutation of CENPJ
Centromere protein J is a protein that in humans is encoded by the ''CENPJ'' gene. It is also known as centrosomal P4.1-associated protein (CPAP). During cell division, this protein plays a structural role in the maintenance of centrosome integrit ...
