WebFeb 22, 2024 · Phenotypic Pleiotropy: The Case of VCP Other genetic diseases, affecting organs and systems seemingly unrelated to the nervous system, have been linked to ALS-FTD continuum ( 3 ). This is the case of genes of minor frequency and involvement such as OPTN, SQSTM1, and VCP, which show remarkable phenotypic pleiotropy. WebApr 3, 2024 · Additionally, pleiotropy may promote repeatability by allowing large fitness benefits of single mutations via adaptive combinations of phenotypic effects. Yet, this latter evolutionary potential may be reaped solely by specific types of mutations able to realize optimal combinations of phenotypic effects while avoiding the costs of pleiotropy.
