The invention relates to RNAi agents, e.g., double-stranded RNAi agents, targeting the TMPRSS6 gene, and methods of using such RNAi agents to inhibit expression of TMPRSS6 and methods of treating subjects having a TMPRSS6 associated disorder, e.g., an iron overload associated disorder, such as β -thalassemia or hemochromatosis.本發明係關於以TMPRSS6基因為靶向之RNAi劑,如雙股RNAi劑,及使用此等RNAi劑抑制TMPRSS6之表現的方法,及治療具有TMPRSS6相關病症,如鐵過載相關病症,如β-地中海貧血或血色素沉著症之受驗者的方法。由於本案的圖皆為實驗數據,並非本案的代表圖。故本案無指定代表圖。
