Abstract

The invention relates to iRNA, e.g., double stranded ribonucleic acid (dsRNA), compositions targeting the serum amyloid P component (APCS) gene, and methods of using such iRNA, e.g., dsRNA, compositions to inhibit expression of an APCS gene and to treat subjects having an APCS-associated disease, e.g., amyloidosis, Alzheimer's disease or coronary atherosclerotic heart disease.
