Applying a fluorescent green tracer called AMDX-9101 during a routine eye exam may enable the detection of the toxic transthyretin protein deposits that cause symptoms of transthyretin amyloidosis (ATTR), a group of conditions that include familial amyloid polyneuropathy (FAP). It’s too early to know if the approach would work…
Gly103Arg, a mutation in the TTR gene that has been exclusively reported in Chinese people, is associated with a familial amyloid polyneuropathy-like profile marked by eye and neurological involvement, according to a case report and literature review study. All three patients from a single family carrying the mutation had…
People with hereditary transthyretin amyloidosis (hATTR), a group of diseases that includes familial amyloid polyneuropathy (FAP), have significantly shorter nerve fibers in their corneas, the eye’s outermost layer, relative to healthy people, a study showed. Shorter corneal nerve fibers could be detected using a noninvasive technique known as corneal…
Long-term treatment with Onpattro (patisiran) is generally safe and results in a stabilization or lessening of neurologic impairments in people with familial amyloid polyneuropathy (FAP), according to a meta-analysis of published studies. Onpattro was used for a mean of 17.4 months (about 1.5 years) among the 503 patients in the…
Nearly every fifth adult with hereditary transthyretin amyloidosis (hATTR), a group of conditions that includes familial amyloid polyneuropathy (FAP), has renal tubular acidosis (RTA) — a problem that occurs when the kidneys fail to remove acids from the blood into the urine. That’s according to a new study from…
People with familial amyloid polyneuropathy (FAP) and other forms of hereditary transthyretin amyloidosis (hATTR) have abnormal blood levels of two proteins, called growth differentiation factor-15 (GDF-15) and uromodulin (Umod), a small study reports. The preliminary findings from 16 patients in Italy suggest GDF-15 and Umod may serve as biomarkers of…
Combination therapy for hereditary transthyretin amyloidosis (hATTR), a group of conditions including familial amyloid polyneuropathy (FAP), appears to be safe, according to a retrospective study, but because its effects “on neurological symptoms could not be assessed,” more studies are needed to confirm its benefits, the researchers wrote. Most of…
Onpattro (patisiran) may help familial amyloid polyneuropathy (FAP) patients who respond poorly to tafamidis meglumine stabilize or have reduced symptoms of nerve damage, called polyneuropathy. The findings are part of of a real-world study in France that analyzed data from 24 patients on tafamidis meglumine, approved as…
The clinical symptoms of hereditary transthyretin amyloidosis (hATTR) — a group of disorders that includes familial amyloid polyneuropathy (FAP) — are highly influenced by the type of mutation in the TTR gene a patient has, a review study concludes. The findings indicate that a clinical profile marked mainly by neurologic problems,…
Onpattro (patisiran), an approved treatment for familial amyloid polyneuropathy (FAP), is now listed on Australia’s Pharmaceutical Benefits Scheme (PBS), meaning that eligible patients in the country can access the therapy at a lower cost. The listing specifically covers Onpattro’s use by adults with a genetic FAP diagnosis…
