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…
Young adults at risk for familial amyloid polyneuropathy (FAP) face unique psychological and social challenges, and likely would benefit from tailored healthcare support when undergoing pre-symptomatic testing for the rare disease. That’s according to a new study by researchers in Portugal, who conducted interviews with more than a dozen…
The first patient has been dosed in a China-based Phase 1/2a clinical trial testing YOLT-201, Yoltech Therapeutics’ one-time gene-editing therapy, in people with hereditary transthyretin amyloidosis (hATTR), a group of diseases that includes familial amyloid polyneuropathy (FAP). Two weeks after receiving the investigational therapy, which was given as…
The oral medication tafamidis meglumine appears to be well tolerated by adults with familial amyloid polyneuropathy (FAP) in France, where the treatment is approved under the brand name Vyndaqel and is often started at an early stage of the disease, a real-world study finds. Easy access to a…
Getting genetic counseling can encourage people at risk for hereditary transthyretin amyloidosis to have genetic testing and know they have the option to seek early treatment if needed, a study suggests. Hereditary transthyretin amyloidosis is a group of diseases that include familial amyloid polyneuropathy (FAP). Having genetic testing can…
Rising levels of a protein called neurofilament light chain (NfL) in the blood may indicate nerve damage due to familial amyloid polyneuropathy (FAP) even before the disease manifests, a study in 65 people reports. These findings suggest that testing for NfL levels could be used to detect nerve damage…
Tegsedi (inotersen) safely and effectively slowed the progression of polyneuropathy, or damage to multiple nerves, when taken for up to about six years for 10 adults with familial amyloid polyneuropathy (FAP) in Brazil, according to a real-world study. While the data add to results of Tegsedi clinical trials,…
The parameters of muscle ultrasound, which uses sound waves to make pictures of muscles, are significantly different among people with familial amyloid polyneuropathy (FAP), those not yet showing overt disease symptoms, and healthy people. That’s according to a small study in Malaysia that suggests this noninvasive imaging scan…
A study of people carrying mutations known to cause familial amyloid polyneuropathy (FAP) found that those with disease symptoms had significantly higher levels of neurofilament light chain (NfL) — a protein that’s a marker of nerve cell damage — in their blood than those who hadn’t shown symptoms, indicating…
Abnormalities in capillaries, or very small blood vessels, and inflammation from increased blood clotting may contribute to nerve damage, or neuropathy, in advanced familial amyloid polyneuropathy (FAP), according to finding that offer new insights into the mechanisms of peripheral nerves damage in FAP, offering potential targets for developing new…
