Amyloidosis can be hereditary or acquired, depending on the specific type of the disease, with hereditary forms specifically caused by mutations in certain genes. It is important to distinguish between the two: acquired (or wild-type) amyloidosis is not inherited and occurs due to age-related protein misfolding, whereas hereditary (or familial) amyloidosis is caused by a genetic mutation passed down through families. The most common form of hereditary amyloidosis is Transthyretin Amyloidosis (hATTR), which follows an autosomal dominant inheritance pattern. Understanding Inheritance and Risk In an autosomal dominant condition like hATTR, an individual only needs one copy of the mutated gene from one parent to potentially develop the disease.

Understanding Inheritance and Risk

In an autosomal dominant condition like hATTR, an individual only needs one copy of the mutated gene from one parent to potentially develop the disease. If a parent has the mutation, there is a 50% chance of passing it to each child. While de novo (spontaneous) mutations can occur, they are significantly less common than inherited cases in the context of known familial amyloidosis clusters.

Genetic Testing and Counseling

Genetic testing is a cornerstone of diagnosis for those suspected of having hereditary amyloidosis. We strongly recommend clinical genetic testing for patients who show symptoms of amyloidosis, particularly if there is a family history of neuropathy, cardiomyopathy, or gastrointestinal issues. Genetic counseling is vital throughout this process to help families navigate the emotional and clinical implications of these results.

For individuals planning a family, genetic counseling provides a space to discuss the implications of hereditary amyloidosis and explore reproductive options, such as Preimplantation Genetic Testing (PGT) during IVF. Carrier testing for relatives of an affected individual is also a standard part of clinical management, as it allows for early monitoring and intervention before symptoms manifest.
