Incidental mutations (data from Mutagenetix , APF )
Homozygous targeted null mutants die at or soon after implantation. Tissue-specific knockouts exhibit skin blisters, hair-loss, brain and heart defects, and impaired immune responses, wound healing, and hematopoietic stem cell migration, respectively.
