In brief: Protective gene

The carrier state exists & thrives because the unaffected allele is able to provide a protective level of the enzyme needed to avoid symptoms.
By providing a basic level of enzyme production, the body can go about its normal metabolic activities without the buildup of toxic materials that cause the disease state.
