A mutation is a permanent change in the DNA sequence of a gene. It may be a minor or a major change; and may be harmful or beneficial.

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.
The disease sickle cell anaemia occurs due to a mutation. This causes the amino acid glutamic acid (which is hydrophilic) in haemoglobin to be replaced by valine (which is hydrophobic).
There are many thousands of different mutations.
it's normal for cells to mutate. Mutation is what made evolution possible. Of course you should not get enough mutation to get cancer. Mutation can also cause disease and cancer, so it can also be a bad thing.
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.
Celiac Disease is a mutation of the HLA-DQ2 or HLA-DQ8 alleles
harmful mutation
Huntington's disease is caused by a gene mutation, specifically in the HTT gene on chromosome 4.
A frameshift mutation in the CARD15 gene
No, it is a dominant gene

no it isn't it is genetic, you inherit it
Celiac disease is primarily associated with specific genetic variations in the HLA-DQ genes, particularly HLA-DQ2 and HLA-DQ8, rather than being caused by a point mutation or frameshift mutation. These variations are typically due to small insertions or deletions that can alter the amino acid sequence, but the disease is more strongly linked to these haplotypes than to a single mutation type. Therefore, while mutations can play a role in the genetic predisposition to celiac disease, it's not accurately characterized solely as a point or frameshift mutation.
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.
One example of a beneficial mutation in genetics is the mutation that causes sickle cell anemia. This mutation provides some protection against malaria, making individuals with this mutation less susceptible to the disease.
