ABetaA21G amyloidosis
Synonyms: ABeta amyloidosis, Flemish type | ABetaA21G-related amyloidosis | HCHWA, Flemish type | Hereditary cerebral hemorrhage with amyloidosis, Flemish type
A form of hereditary cerebral hemorrhage with amyloidosis characterized by an age of onset of 45 years of age progressive Alzheimer’s disease-like dementia and lobar intracerebral hemorrhage in some patients. This subtype is due to a mutation in the APP gene (21q21.2) encoding the beta-amyloid precursor protein. This mutation causes an increased accumulation of amyloid-beta protein in the walls of the arteries and capillaries of the meninges cerebellar cortex and cerebral cortex leading to the weakening and eventual rupture of these vessels.

To make a positive and lasting impact in New Zealand, helping Amyloidosis disease patients from various disease subgroups ( AL, AA, hATTR, Wild Type) by working with local and international doctors, pharma treatment entities, as well as government agencies to bring approved funded treatment drugs into NZ for suffering patients. We desire to help build a lasting support system within the NZ health framework. We want an excellent wrap-around network of care to achieve for the sufferer to achieve a positive outcome in their well-being. This mission includes the wellness of the patient's caregiver and family whose needs, we feel, have been neglected.
