ATTR amyloidosis is a form of systemic amyloidosis caused by amyloid deposits made up of a protein called transthyretin (TTR). ATTR amyloidosis can be either hereditary or acquired (non-hereditary). TTR is always present in the blood, where it transports thyroid hormone and vitamin A (retinol), hence the … See more Hereditary ATTR amyloidosis is caused by a mutation in the gene for TTR, inherited from one parent.
