Types of changes we may find

Every person has variations in his or her genome that make him or her unique. Most of these changes do not have any effect on our physical appearance, risk for diseases, or our behavior.

There are four types of changes researchers may find in a person’s genome:

  1. Normal variations: changes in genes that are not known to cause any disease or health problem. We will find normal variations in the genome of everyone we study.

  2. Disease-causing variations: changes in genes that cause disease.

  3. Disease-risk variations: changes in genes that affect your risk of developing a disease.

  4. Unknown or new variations: changes that we do not know what they mean. Some changes will be new and we may not know if they contribute to disease or if they are normal variations.

My46 is an innovative web-based tool that enables individuals to manage their own genetic testing results.

Your genome is your entire genetic code or all of the DNA in a cell.

What My46 Means

Most human cells have 46 chromosomes that provide the genetic instructions for a body to live, grow, and develop.
