Phenylketonuria Research Paper

Introduction Phenylketonuria has been defined as a form of genetic abnormality that an individual acquires due to lack of PAH enzyme reduction that makes that individual unable to metabolize phenylalanine tyrosine. On the other hand, Down syndrome has been referred to a type of genetic condition that makes an individual to experience some sort of learning disability as well as different characteristic physical features. Down syndrome is also defined as a birth condition that is experienced by individuals who are born with an extra copy of chromosome 21.
Individuals who experience this condition tend to experience different physical issues and intellectual disabilities as well. People who are born with Down syndrome are usually unique in a way and may have different healthcare conditions. Some of the conditions that these
To start with, it is important to note that phenylketonuria happens to be one of the best examples that can be used to explain the effects of environmental modification of a hereditarily restricted impact. Phenylketonuria is defined as a form of mental retardation that is brought about by the damaging effects of the abnormal breakdown of the important body amino acids and phenylalanine that are usually found in all proteins. Additionally, the specific enzyme that breaks down phenylalanine is usually defective as it accumulates and breaks down in an abnormal manner. The meaning of this is that, to those who suffer from phenylketonuria, it is possible for a single gene to impact his or her behavior and it happens to present a genetically influenced process. Additionally, it is important to note that Trisomy 21- chromosomal abnormality that results in either a partial or full extra chromosome 21 copy leads to mental retardation, motor skill deficit, and cognitive deficit among other serious health
