Huntington's disease is caused by a gene mutation, specifically in the HTT gene on chromosome 4.
No, it's caused by a single point mutation of a gene.

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.
sickle-cell anemia.
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.
For example, some diseases caused by insertional mutations include: Fragile X Syndrome. Huntington's Disease. Myotonic dystrophy. Cystic fibrosis.
There are many thousands of different mutations.
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.RegardsTime is imaginary
Cystic fibrosis is primarily caused by mutations in the CFTR gene, which is located on chromosome 7. These mutations can result in a defective or non-functioning CFTR protein, leading to the characteristic symptoms of the disease.
Monogenetic disorders are caused by a mutation in a single gene. The mutation may be present on one or both chromosomes (one chromosome inherited from each parent). Examples of monogenic disorders are: sickle cell disease, cystic fibrosis, polycystic kidney disease, and Tay-Sachs disease.
