Breast and Colon Cancer

The BRCA1 and BRCA2 inherited genes are responsible for breast or ovarian cancer. However, all breast cancers are not genetic. Colon cancer is also genetic.

Sickle Cell Disease

This gene protects people from malaria. If you get the gene from both parents, then the red blood cells ‘sickle’. They get stuck in capillaries and destroy organs and joints. So, the victims eventually die of organ failure.

Hemophilia

It is a bleeding disorder that happens due to the absence of genetic clotting factors. It can be inherited from single or both parents. You can manage it by replacing the missing factor.
