Next-generation sequencing to analyze a panel of 11 specific genes may facilitate the diagnosis of amyloidosis, including familial amyloid polyneuropathy (FAP), according to researchers from the Czech Republic. The new approach was described in the study, “Newly designed 11-gene panel reveals first case of hereditary amyloidosis…
Alnylam Pharmaceuticals’ investigative patisiran treatment improves overall health and prevents worsening of walking ability in patients with familial amyloid polyneuropathy (FAP), according to a new analysis from the APOLLO Phase 3 study. FAP, also known as hereditary ATTR (hATTR) amyloidosis, is caused by mutations of the transthyretin (TTR) gene…
Familial amyloid polyneuropathy (FAP) patients who do not have a Val30Met mutation exhibit prevalent cardiac and blood vessel dysfunction, but proper blood vessel constriction remains intact, even in patients with advanced nerve damage, a study suggests. The study, “Widespread Cardiac and Vasomotor Autonomic Dysfunction in Non-Val30Met Hereditary…
Treatment with the investigative therapy Tegsedi (inotersen) provides early and significant improvements in neuropathy symptoms and quality of life in patients with familial amyloid polyneuropathy (FAP), according to results from a pivotal Phase 2/3 clinical trial.
