A mutation can cause disease if

When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.

How can a mutation occur and not affect an organism?

A mutation can have no effect to an organism if the mutation occurs in a region that does not affect gene products or gene functions . This can happen if the mutation occurs at the non-coding region of the DNA or if the mutation occurs at a coding region, but does not change the final amino acid sequence of the gene product.

Which diseases can result from this type of mutation?

Single inheritance Huntington’s disease. Huntington’s disease develops due to a mutation on a dominant allele within chromosome 4. People… Sickle cell diseases. Sickle cell diseases (SCDs) are a group of conditions that affect red blood cells. Sickle cell… Muscular dystrophies. Muscular dystrophies are a group of genetic conditions that cause muscle damage and… More

What kind of mutations can cause cancer?

There are 2 basic types of genetic mutations: Acquired mutations. These are the most common cause of cancer. They occur from damage to genes in a particular cell during a person’s life. For example, this could be a breast cell or a colon cell, which then goes on to divide many times and form a tumor.

How mutations can cause cancer?

If a person has an error in a DNA repair gene, mistakes remain uncorrected. Then, the mistakes become mutations. These mutations may eventually lead to cancer, particularly mutations in tumor suppressor genes or oncogenes. Mutations in DNA repair genes may be inherited or acquired.

How could a mutation affect an organism?

Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.

How do mutations affect phenotypes?

No change occurs in phenotype. Some mutations don’t have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein .

When is a mutation harmful to an organism?

Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.

What effects do mutations have on organisms?

Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.
