How many diseases are caused by genes?

Answer 1

Gene is defined as a functional unit of hereditary. Genes are unique to individual. Genes carry information through DNA. No gene is responsible for any disease unless it is a defective gene. A gene becomes defective initially in any individual due to mutations in chromosomes that is a base pair change in DNA. In some cases like hemophilia these defective genes are passed to next generations also.That cannot be called as a disease rather we can call it as a disorder or defect.

Disease is abnormal change in body that is caused due to a microorganism.

Answer 2

It only takes one mutated gene to cause a genetic disease. For example, in sickle cell anemia, a single misplaced base pair on a gene causes a protein in red blood cells to become malformed. As a result, the blood cells are sickle shaped and no longer function as they should. Just that one point mutation in that one protein caused a serious problem in individuals with that gene.

Answer 3

There are thousands of diseases caused by genetic mutations, estimated to be around 6,000 to 8,000. These include conditions such as cystic fibrosis, Huntington's disease, and sickle cell anemia. Genetic testing and advancements in genomics continue to uncover more diseases with a genetic component.
