Missence mutation
a silent mutation.
Yes, Proteus syndrome is caused by a post-zygotic somatic mutation in the AKT1 gene. This mutation leads to overgrowth of various tissues in the body, resulting in characteristic features of the syndrome.
A negative mutation is one which is harmful to the organism. The result of a negative mutation is a non-sense protein. Examples of negative mutations include:a frame shift mutation - codons are read wrongan insertion mutation - insertion of a sequence of extra nucleotidesa deletion mutation - deletion of a chain of nucleotidesa non-sense mutation - results in the creation of a non-sense proteina transition mutation - exchange of purines to pyrimidines thus changing the nucleotide sequence and resulting in a mutation.
This type of mutation is called a deletion mutation. It can lead to a frameshift mutation if the number of nucleotides deleted is not a multiple of three, resulting in a change in the reading frame and potentially producing a nonfunctional or altered protein. Deletion mutations can have significant impacts on the resulting phenotype.

Deletion mutations can have significant impacts on the resulting phenotype.
Huntington's disease is an example of a lethal dominant mutation. It is a neurodegenerative disorder caused by a dominant mutation in the HTT gene, leading to progressive loss of motor and cognitive functions, eventually resulting in death.
Missense mutation: changes one sense codon to another, resulting in incorporation of amino acid.Nonsense mutation: changes a sense codon into a stop (or nonsense) codon, resulting in premature termination.
Individuals with a mutation can pass it on to their offspring because the mutation is present in their germline cells (sperm or eggs), which are used to create offspring. This means that the genetic mutation is incorporated into the DNA of the offspring, resulting in them inheriting the mutation.
A mutation in which a single base is added to or deleted from DNA is called an insertion or deletion mutation, also known as an indel mutation. This can lead to a shift in the reading frame during translation, causing significant changes in the resulting protein sequence and potentially leading to functional consequences.
Both a silent and missense mutation is a change in one nucleotide. However, a silent mutation still codes for the same amino acid, but a missense mutation codes for a different amino acid. This means that a silent mutation will have no affect on the resulting protein, but a missense mutation will. Still, it is not guaranteed that a a missense mutation will result in a disfunction of created protein, as long as it is not occurring in the activation site.
