Symptoms and Causes

“To know what causes genetic problems, first we need to understand how our genes and DNA work.” Most of the DNA in your genes gives your body the instructions it needs to make proteins. These proteins control how your cells grow, work, and stay healthy.

Sometimes, a change (called a mutation) happens in the DNA. This change can affect the instructions for making proteins. Because of this, your body might not make enough protein, or the protein might not work the right way.

To understand why some people have genetic disorders, it helps to know a little about genes and DNA. Your genes are like instruction books that tell your body how to grow and work. Most of these instructions help your body make proteins.

Proteins are very important. They help your cells stay healthy and do their jobs the right way.

Sometimes, a small change happens in the genes. This is called a mutation. It can cause your body to make the wrong protein, not enough of it, or none at all. This can lead to health problems.

Some changes in genes can happen because of things around us, like harmful chemicals or strong rays from the sun. These are called mutagens.

• Things That Can Change or Harm Your Genes:
• Bad chemicals – like some in sprays or factories
• Radiation – strong energy from X-rays or machines
• Smoking – using cigarettes or being near someone who smokes
• Too much sunlight – staying in the sun too long without covering your skin
