 IMPC Activities

 Undertake broad based primary phenotyping of 20,000
  mutants from the IKMC resource
    A coordinated effort of mouse clinics worldwide

 Phase I (2011-2016): phenotype up to 5,000 lines
    Pipeline development, logistics
    Phenotyping technology developments e.g. imaging
    Ramp up

 Phase II (2016-2021): Phenotype 15,000 mutants

 Data freely available through a Data Coordination
  Centre, supported by R&D groups at clinics
