Diseases Caused By Gene Mutations

There are thousands of genetic diseases in the world that affect people’s health. Some of these are passed down from one generation to another or skip a generation. Others are influenced by the atmosphere altering a segment of their DNA. This incidence is called a gene mutation and it can studied with a custom microarray. Here are a few illnesses caused by gene mutation.


The genes in your body instruct how your body makes proteins. When something affects the gene and influences it to make a tainted protein instead, the gene mutates. When several of the genes change like this, a mass forms. This mass is typically a cancerous tumor. Chemicals we eat or breathe, age, radiation and tobacco can cause genes to mutate and become cancerous.

Cystic Fibrosis

This disease is also the mutation of a gene but instead of sending an abnormal signal, the gene sends no signal. This causes an imbalance in the chloride and fluid on the surface of a cell, or the CFTR gene. When several cells do this, it leads to problems with the lungs and other vital organs. However, you get a CFTR gene from both of your parents and to be diagnosed with Cystic Fibrosis both genes have to mutate.

Sickle Cell Anemia

Sickle Cell Anemia happens when the gene that dictates the level of oxygen in your blood mutates. This makes the cell itself warp until it looks like a sickle or a crescent moon. This can make the patient suffer pain, shortness of breath, and can damage organs after time. It normally is found in children.

Huntington’s Disease

This illness occurs when the HTT gene goes through a mutation and distorts the protein that it makes. This causes issues with movement, depression and memory. While it is unknown the place where this protein serves, it is believed that it affects the brain since the effects stem from there.
