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.

∙ 13y agoIt 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.

Are infectious diseases caused by human genes?
While a person's genes may make him or her more or less susceptible to a particular infectious disease, infectious disease are not caused by genes. Infectious diseases are caused by microorganisms (bacteria, viruses) that multiply in the body and that can be transferred from one person to another.

Describe three ways genetic diseases are caused?
1. (1) Produced by an abnormality in, or a mutation of the genetic code in a single gene; (2) Caused by several abnormal genes (Producing so-called polygenic diseases); or (3) Caused by the abnormal presence or absence of an entire chromosome or by alteration in the structure of chromosomes.
