WebPleiotropy is a phenomenon increasingly recognized by the usage of hypothesis-free exome sequencing rather than candidate gene approaches to identify novel disease genes. It refers to the effect that mutations in one and the same gene may lead to multiple, seemingly unrelated diseases. WebJun 8, 2024 · Pleiotropy. Some genes affect more than one phenotypic trait. This is called pleiotropy. There are numerous examples of pleiotropy in humans. They generally involve …

Pleiotropy describes the genetic effect of a single gene on multiple phenotypic traits. The underlying mechanism is genes that code for a product that is either used by various cells or has a cascade-like signaling function that affects various targets. See more Pleiotropy (from Greek πλείων pleion, 'more', and τρόπος tropos, 'way') occurs when one gene influences two or more seemingly unrelated phenotypic traits. Such a gene that exhibits multiple phenotypic … See more Most genetic traits are polygenic in nature: controlled by many genetic variants, each of small effect. These genetic variants can reside in protein coding or non-coding regions of the genome. In this context pleiotropy refers to the influence that a specific genetic … See more Pleiotropy can have an effect on the evolutionary rate of genes and allele frequencies. Traditionally, models of pleiotropy have predicted that evolutionary rate of genes is … See more • cis-regulatory element • Enhancer (genetics) • Epistasis • Genetic correlation • Metabolic network See more Pleiotropic traits had been previously recognized in the scientific community but had not been experimented on until Gregor Mendel's … See more One basic model of pleiotropy's origin describes a single gene locus to the expression of a certain trait.
