Cells can sometimes contain changes in the information in their genes.
This is called gene mutation , and it often occurs when cells are aging or have been exposed to certain chemicals or radiation. Fortunately, cells usually recognize these mutations and repair them by themselves. Other times, however, they can cause illnesses. And if the gene mutation exists in egg or sperm cells, children can inherit the mutated gene from their parents. Researchers have identified more than 4,000 diseases that are caused by genetic defects.
