ATTR amyloidosis, A for Amyloid and the TTR is an abbreviation used for the protein “transthyretin.” ATTR amyloidosis is a rare disease, caused by the build-up of abnormal protein deposits in various tissues of the body. Amyloid deposits cause disorder by damaging the structure and the function of the organs where they are found and they can affect almost any part of the body.
There are three different types of ATTR Amyloidosis: Familial Amyloid Polyneuropathy (FAP), which affects the nervous system, often the heart and sometimes the kidneys and eyes. Second is, Familial Amyloid Cardiomyopathy (FAC), which is a hereditary, genetic condition, caused by mutations in the TTR gene resulting in production of the abnormal TTR and the last is, Senile Systemic Amyloidosis (SSA) which is not hereditary and a slowly progressive disease. It is far more prevalent in men than in women. Methods to diagnose ATTR include tissue biopsy, genetic testing and imaging studies of the heart.
The global ATTR market is expected to experience robust growth post the launch of ATTR therapeutic drugs, primarily due to increasing African-American population, increasing health care expenditure and accelerating economic growth. However, the growth of this budding market is is hindered by the stringent regulations, high cost of ATTR drugs, misdiagnosis of ATTR disorder and limitation of clinical trials.
