hATTR Understanding

Transthyretin (earlier known as prealbumin) is an abundant, soluble, β-strand rich 55 kDa homotetramer serum protein that is responsible for the transportation of both vitamin A (via retinol-binding protein) and thyroxin throughout the body. TTR is also involved in the binding and redistribution of β-amyloid in the choroid plexus as well as in the retention of T4 in the cerebral spinal fluid (CSF). TTR may sometimes dissociate into its 127-amino acid monomeric subunits and undergo aberrant changes to form amyloidogenic intermediates. These intermediates then might self-associate to become amyloid fibrils that accumulate as amyloid deposits throughout the body, resulting in Transthyretin Amyloidosis.  Transthyretin Amyloidosis (ATTR) can be sub-classified as wild-type (wt) or hereditary, and the latter is then further sub-divided into familial amyloid polyneuropathy (FAP) and familial amyloid cardiomyopathy (FAC).

The hereditary forms of amyloidosis are autosomal dominant diseases characterized by deposition of variant proteins, in distinctive tissues. The most common hereditary form is transthyretin amyloidosis (ATTR) caused by the misfolding of protein monomers derived from the tetrameric protein transthyretin (TTR). Mutations in the gene for TTR frequently result in instability of TTR and subsequent fibril formation. Closely related is wild-type TTR in which the native TTR protein, particularly in the elderly, can destabilize and re-aggregate causing nonfamilial cases of TTR amyloidosis.

Familial transthyretin amyloidosis (FTA) is caused by changes (mutations) in the TTR gene. This gene is responsible for making a protein called transthyretin which transports vitamin A and a hormone called thyroxin too many parts of the body. Mutations in TTR lead to a transthyretin protein that is not made correctly. The faulty protein then folds up to form amyloid. Amyloid builds up in various parts of the body causing nerve and tissue damage. Most people who have FTA have inherited the TTR mutation from a family member. However, a few people with FTA will have no family history of the disease and have a new (de novo) mutation in the TTR gene.

hATTR Diagnosis

Disease heterogeneity and its rarity make a diagnosis of hATTR amyloidosis challenging. However, making a correct diagnosis is vital to determining prognosis, treatment, and appropriate patient and family counseling. Timely diagnosis is also important because it allows patients the opportunity to receive appropriate care as early as possible in the disease course.

Diagnosis can be confirmed via biopsy of the affected tissue or organ followed by staining with Congo red to confirm the presence of amyloid. Diagnosis can be established less invasively through biopsy of the salivary gland, endoscopic biopsy of the gastric mucosa, or subcutaneous fat aspiration. Western blot analysis, immunohistochemical staining, laser microdissection, proteomics, and mass spectrometry are subsequently used to characterize amyloid type. Limitations of biopsy are due to the often patchy distribution of amyloid deposits, sometimes necessitating multiple biopsies to confirm or exclude the diagnosis. Additionally, biopsy sensitivity depends on multiple factors, such as pathologist experience and protocol for Congo red staining. In patients with a family history of disease and/or evaluation of symptomatic burden (ie, polyneuropathy), genetic testing is a crucial component to confirm a hATTR amyloidosis diagnosis as it identifies the specific TTR mutation present. Presymptomatic testing is now widely available and may be performed at the request of the patient with appropriate genetic counseling and follow-up.

Initial laboratory testing should include a complete blood count with red cell indices, HPLC or Hb electrophoresis, and eventually α/β-globin chain synthesis ratio measurement. The latter procedure, however, is sometimes bypassed by DNA analysis as a less complicated method to diagnose α- thalassemia.
