Historically, FAP was considered a neglected disease due to its rarity and the limited understanding of its pathophysiology, which led to minimal research funding and few therapeutic options. The present article explores the transformative role of Centro de Paramiloidose Antônio Rodrigues de Mello (CEPARM), established in 1984, in elevating the status of FAP through significant advancements in research and treatment. Although CEPARM was not the sole catalyst for this shift, its contributions in liver transplantation, the development of pharmacological therapies, and holistic patient care have substantially improved the recognition and management of FAP. The article also examines CEPARM’s impact on patient care, the ongoing challenges, and ethical considerations within the field.  \nINTRODUCTION  \nFamilial amyloidotic polyneuropathy (FAP), now more commonly known as variant transthyretin amyloidosis (ATTRv), encompassing polyneuropathy (ATTRv-PN) and cardiomyopathy (ATTRv-CM), is a progressive and life-threatening disorder caused by mutations in the transthyretin (TTR) gene. These mutations result in misfolded TTR proteins that form amyloid deposits, primarily affecting peripheral nerves in ATTRv-PNand the heart in ATTRv-CM. 1,2  \nHistorically, FAP was regarded as a low-prestige disease, largely neglected due to its rarity and the limited understanding of its mechanisms. This lack of recognition led to minimal research funding and scarce treatment options.

However, growing interest from the pharmaceutical industry, coupled with an increased focus on rare diseases, has been pivotal in transforming its status and improving the outcomes.3,4  \nVariant transthyretin amyloidosis was initially considered a disease confined to endemic foci in Portugal, Japan, and Sweden. However, the presence of late-onset cases in endemic and non-endemic areas has now been recognized, indicating that the disorder is more common than previously thought. 5,6  \nTHE EARLY YEARS OF CEPARM  \nCentro de Paramiloidose Antônio Rodrigues de Mello (CEPARM) was established in 1984 at Hospital Universitário  \n© 2025 .
