Wild-type ATTR

key information

source: Amyloidosis Foundation

year: N/A

summary/abstract:

Wild-type ATTR is also referred to as ATTRwt. It is not caused by any known genetic mutations, such as in the case of hereditary forms of the disease (hATTR). This disease used to be called SSA or SCA, which stood for Senile Systemic Amyloidosis and Senile Cardiac Amyloidosis, respectively, which are now outdated terminologies. The disease is not known to be directly related to dementia, but it is related to aging.
 
Deposits of TTR amyloid can be found throughout the body, so it is a systemic amyloidosis disease.  The most common place it is found is in the heart. Wild-type ATTR is also known to cause some cases of carpal tunnel syndrome, which can be the first (early) symptom. Recent data suggests that lumbar spine involvement as well as a rupture of the biceps tendon in the forearm can precede cardiac involvement by many years.
