Pleiotropic gene

Vedclass · Answer

(B) The phenomenon where a single gene influences multiple,seemingly unrelated phenotypic traits 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 metabolic defect results in a syndrome characterized by various symptoms,including mental retardation,reduction in hair and skin pigmentation,and other physiological abnormalities.Since one gene is responsible for this wide range of phenotypic effects,it is classified as a $Pleiotropic$ gene.

In humans,the gene responsible for Phenylketonuria produces multiple phenotypic expressions,collectively known as a syndrome. This gene causes mental retardation,broad incisor teeth,skin pigmentation,and excessive sweating. What is this type of gene called?
