- A gene knock-in (or knock-in) refers to a genetic engineering method that involves the one-for-one substitution of DNA sequence information in a genetic locus or the insertion of sequence information not found within the locus. A gene knock-in therefore can be seen as a gain of function mutation and a gene knockout a loss of function mutation, but a gene knock-in may also involve the substitution of a functional gene locus for a mutant phenotype that results in some loss of function.
