Genetic Testing for Autosomal Dominant Hypercholesterolemia

APOB Mutation-Positive

December 2008

If an APOB mutation is identified, testing is stopped and an interpretive report is provided. Because a mutation has been identified in a patient, genetic counseling should be pursued and it may be important to consider ordering test 89097 to investigate the possibility of the same APOB mutation in an at-risk family member.
