Because AAT deficiency is an inherited disease, meaning it runs in families, it cannot be prevented. It can happen to anyone of any race or ethnicity. However, it is more common in white people of Northern-European backgrounds.

Everyone inherits two AAT genes, one gene from each parent. If you inherit a mutated, or changed gene from each parent, you will have AAT deficiency.

If you inherit a mutated AAT gene from one parent and a normal AAT gene from the other parent, you are a carrier for the condition. You might have lower levels of AAT protein in your blood, but you most likely will not have AAT deficiency. You might also pass the mutated gene to your children.
