Phenylketonuria (PKU) is primarily caused by a genetic mutation in the PAH gene, which encodes the enzyme phenylalanine hydroxylase. This mutation is often a point mutation, which involves a single nucleotide change in the DNA sequence that can lead to a dysfunctional enzyme. However, PKU can also result from other types of mutations, including deletions or insertions, but point mutations are the most common cause.
What else can I help you with?
Is pku a point shirt or a frameshift mutation?
PKU (phenylketonuria) is a point mutation, specifically an autosomal recessive genetic disorder caused by a mutation in the PAH gene. This mutation leads to impaired metabolism of the amino acid phenylalanine. It is not a frameshift mutation, which would involve an insertion or deletion of nucleotides, shifting the reading frame of the gene.
A change in a single nucleotide in DNA-?
A mutation
How possible is it that a parent can pass phenylketonuria to its offspring?
It is possible for a parent with phenylketonuria to pass the condition to their offspring if both parents are carriers of the PKU gene mutation. In this case, there is a 25% chance that their child will inherit two copies of the mutated gene and develop phenylketonuria. Genetic testing can provide more information on the risk of passing PKU to offspring.
The substitution addition or removal of a single nucleotide in DNA is called a what mutation?
The substitution, addition, or removal of a single nucleotide in DNA is called a point mutation. This type of mutation can result in changes to the amino acid sequence of a protein, leading to potential functional consequences.
Why is point mutation dangerous?
A frame shift mutation destroys the correct sequence of amino acids from the point of the mutation. The protein produced by a frame shift mutation would more than likely be nonfunctional.
Is pku a point shirt or a frameshift mutation?
PKU (phenylketonuria) is a point mutation, specifically an autosomal recessive genetic disorder caused by a mutation in the PAH gene. This mutation leads to impaired metabolism of the amino acid phenylalanine. It is not a frameshift mutation, which would involve an insertion or deletion of nucleotides, shifting the reading frame of the gene.
What is the treatment for phenylketonuria?
The best treatment of phenylketonuria is a diet that is extremely low in phenylalanine during childhood. A person can also take fish oil supplements and iron supplements to help treat some of the symptoms.
A change in a single nucleotide in DNA-?
A mutation
A mutation that involves a single nucleotide is called a(an)?
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
A mutation that involves one or a few nucleotides is called a?
Sorry to burst the persons bubble that said frameshift mutation but its wrong. Point mutation-gene mutation involving changes in one or a few nucleotides. point mutation
How possible is it that a parent can pass phenylketonuria to its offspring?

In this case, there is a 25% chance that their child will inherit two copies of the mutated gene and develop phenylketonuria. Genetic testing can provide more information on the risk of passing PKU to offspring.
Mutations that change one or just a few of nucleotides in a gene on a chromosome are called what?
the correct answer is C. a substitution i know this cause i have this book to this question and point mutation is not one of the answer and i found the answer in the book -No its substituton you jack wagon your books wrong
What is phenylketonuria?
phenylketonuria
What are mutations that occur at a single point?
Such mutations are called point mutation or gene mutation.
What is Phenylketonuria PKU?
phenylketonuria
Can a point mutation result in a frameshift mutation?
Yes, a point mutation can result in a frameshift mutation if it occurs in a coding region of a gene and disrupts the reading frame of the genetic code.
A mutation that involves a single nucletiode is called an?
point mutation
