However not all individuals with a mutation in a gene that causes hereditary amyloidosis will develop signs and symptoms of the disease. Transthyretin amyloidosis is a slowly progressive condition characterized by the buildup of abnormal deposits of a protein called amyloid amyloidosis in the bodys organs and tissues.

Each child of an individual affected with hereditary amyloidosis has a 50 1 in 2 risk to inherit the disease-causing mutation and a 50 chance of not inheriting the mutation. Without treatment it eventually leads to death. At least 37 human proteins are known to form amyloid fibrils in vivo.
People with hereditary ATTR amyloidosis carry mutations in the TTR gene. It is evident that the amyloid syndromes display.

Primary cutaneous amyloidosis is a form of amyloidosis a group of conditions in which an abnormal protein called amyloid builds up in various organs and tissues throughout the body. Amyloidosis is a generic term that refers to the extracellular tissue deposition of fibrils composed of low molecular weight subunits 5 to 25 kD of proteins many of which are normal constituents of serum. The signs and symptoms of AL amyloidosis vary among patients because the build up may occur in the tongue intestines muscles joints nerves skin ligaments heart liver spleen or kidneys.
In the broad classification adopted here the disorders have for convenience been grouped according to the anatomical system that is predominantly affected. The type and location of an amyloid gene abnormality can affect the risk of certain complications the age at which symptoms first appear and. Amyloidoses must at present depend largely upon clinical subdivisions.
The intended audience for the GTR is health care providers and researchers. Many different types of gene abnormalities present at birth are associated with an increased risk of amyloid disease. Each child of an affected individual who is heterozygous for one TTR pathogenic variant has a 50 chance of inheriting the TTR variant.
