Introduction to IMPC Embryo Data
Up to one third of homozygous knockout lines are lethal, which means no homozygous mice or less than expected are observed past the weaning stage (IMPC Viability Primary Screen procedure). Early death may occur during embryonic development or soon after birth, during the pre-weaning stage. For this reason, the IMPC established a systematic embryonic phenotyping pipeline to morphologically evaluate mutant embryos to ascertain the primary perturbations that cause early death and thus gain insight into gene function.
