Pleiotropy Is Not Polygenic Inheritance | Learn Science at Scitable

One of the most widely cited examples of pleiotropy in humans is phenylketonuria (PKU). This disorder is caused by a deficiency of the enzyme phenylalanine hydroxylase, which is necessary to convert the essential amino acid phenylalanine to tyrosine.

Pleiotropy and lethal alleles (article) | Khan Academy

A human genetic disorder called Marfan syndrome is caused by a mutation in one gene, yet it affects many aspects of growth and development, including height, vision, and heart function. This is an example of pleiotropy, or one gene affecting multiple characteristics. A cross between two heterozygous yellow mice produces …

Pleiotropy: One Gene Can Affect Multiple Traits – Nature

A pleiotropic gene is a single gene that controls more than one trait. … Genes that affect multiple, apparently unrelated, phenotypes are thus called pleiotropic genes (Figure 1). Pleiotropy should not be confused with polygenic traits, in which multiple genes converge to result in a single phenotype.
