- A gain-of-function mutation is a genetic lesion that causes the normal product of a gene to be expressed inappropriately (at abnormally high levels and/or at the wrong time or location), or to acquire a new abnormal function through alteration of the gene product itself.

Gain-of-function research - Wikipedia
Gain-of-function research (GoF research or GoFR) is medical research that genetically alters an organism in a way that may enhance the biological functions of gene products. This may include an altered pathogenesis, transmissibility, or host range, i.e., the types of hosts that a microorganism can infect. This research is intended to reveal targets to better predict emerging infectious diseases and to develop vaccines and therapeutics. For example, influenza B can infect only hum…
