Often a gene is responsible for several phenotypic traits and it is said to be pleiotropic.Pleiotropy occurs when one gene influences two or more seemingly unrelated phenotypic traits. WebHowever, with advancement in genetics and the discovery of the molecular basis of several of these disorders, it is becoming clear that phenotypic pleiotropy exists, that is, the same variant may give rise to a variety of phenotypes, and the classical understanding of these disorders requires a new paradigm. pru adviser international
