The 'treatable' tag has been added due to new therapies available that target this gene. Inotersen is an antisense oligonucleotide inhibitor of mutant and wild-type human transthyretin (TTR), developed and approved by NICE for the treatment of hereditary transthyretin amyloidosis (hATTR) (PMID: 30120737, https://www.nice.org.uk/guidance/hst9/chapter/1-Recommendations). Patisiran is a small interfering RNA (siRNA) molecule that targets the transthyretin gene (TTR) messenger mRNA (mRNA), to suppress both mutant and wild-type amyloid transthyretin (ATTR) protein production. This drug has been approved by NHSE for treatment of transthyretin-mediated amyloidosis (https://www.bbc.co.uk/news/health-48907976).Created: 9 Jul 2019, 12:47 p.m. | Last Modified: 9 Jul 2019, 12:47 p.m.
