E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Hereditary Transthyretin-mediated Amyloidosis (hATTR amyloidosis) |
amiloidosis hereditaria por transtiretina (amiloidosis hATTR). |
|
E.1.1.1 | Medical condition in easily understood language |
hATTR is a hereditary disease caused by protein aggregates in the heart and the nervous system. It leads to heart dysfunction, damages to the nerves, and gastrointestinal and bladder dysfunctions. |
