An antimorphic gene refers to a gene that produces a protein which blocks or interferes with the normal function of another gene. Synonyms for this term would include dominant negative genes, which have a similar effect of preventing normal gene function. Other related terms include loss-of-function genes, which result in reduced or absent protein activity, and hypertrophic genes, which produce proteins that cause excessive tissue growth. Additionally, some may use the term deleterious gene as a broad term for any gene with a negative impact on an organism's health or development, including antimorphic genes. Ultimately, understanding these different terms can help researchers better classify and study the effects of genetic mutations.
