Phenylketonuria

Vedclass · Answer

(B) The phenomenon where a single gene mutation results in multiple phenotypic expressions is known as $Pleiotropy$. In the case of $Phenylketonuria$ $(PKU)$,the mutation in the gene encoding the enzyme $phenylalanine$ $hydroxylase$ leads to the accumulation of $phenylalanine$. This single genetic defect causes multiple phenotypic effects,including mental retardation,reduction in hair pigmentation,and skin lesions. Therefore,$Phenylketonuria$ is a classic example of $Pleiotropy$ in humans.
