Most genetic diseases cannot be cured, but they usually can be treated this statement is true.

Further Explanation:

Genetic diseases result from the mutation in complete or in part of gene by changing in the DNA sequence. Genetic disease mainly develop by a mutation in one gene called monogenic disorder and mutations in more than one genes called multifactorial disorder.

Mutation can occur due to radiations, environmental factor and changing in chromosome position.

Genetic disease mainly of two types are:

• Hereditary

• Non-hereditary

Hereditary diseases are caused due to mutations that are passing from the parents and present in person at the time of birth, like sickle cell anemia.

Non–hereditary is caused due to mutations in one gene or more than one gene that occurs due to new mutation in gene. This type of mutation results from change in the position of gene or change in no. or chromosome. They are not inherited from parents.

Genetic disease can be dominant or recessive and x-linked or y-linked. Genetic disease cannot easily cure because we can’t change the mutation but we can treat the mutation. Treatment can be done through therapy or drugs.
