[https://www.uniprot.org/uniprot/TTHY_HUMAN TTHY_HUMAN] Defects in TTR are the cause of amyloidosis transthyretin-related (AMYL-TTR) [MIM:[https://omim.org/entry/105210 105210]. A hereditary generalized amyloidosis due to transthyretin amyloid deposition. Protein fibrils can form in different tissues leading to amyloid polyneuropathies, amyloidotic cardiomyopathy, carpal tunnel syndrome, systemic senile amyloidosis. The disease includes leptomeningeal amyloidosis that is characterized by primary involvement of the central nervous system. Neuropathologic examination shows amyloid in the walls of leptomeningeal vessels, in pia arachnoid, and subpial deposits. Some patients also develop vitreous amyloid deposition that leads to visual impairment (oculoleptomeningeal amyloidosis). Clinical features include seizures, stroke-like episodes, dementia, psychomotor deterioration, variable amyloid deposition in the vitreous humor.<ref>PMID:11243784</ref> <ref>PMID:15735344</ref> <ref>PMID:19167329</ref> <ref>PMID:3818577</ref> <ref>PMID:3022108</ref> <ref>PMID:6651852</ref> <ref>PMID:6583672</ref> <ref>PMID:3135807</ref> <ref>PMID:1517749</ref> <ref>PMID:1932142</ref> <ref>PMID:7923855</ref> <ref>PMID:8382610</ref> <ref>PMID:8428915</ref> <ref>PMID:9733771</ref> <ref>PMID:12403615</ref> <ref>PMID:16185074</ref> <ref>PMID:16627944</ref> <ref>PMID:6487335</ref> <ref>PMID:3722385</ref> <ref>PMID:2891727</ref> <ref>PMID:2161654</ref> <ref>PMID:2363717</ref> <ref>PMID:1656975</ref> <ref>PMID:2046936</ref> <ref>PMID:1570831</ref> <ref>PMID:1734866</ref> <ref>PMID:1520326</ref> <ref>PMID:1520336</ref> <ref>PMID:1544214</ref> <ref>PMID:1351039</ref> <ref>PMID:1301926</ref> <ref>PMID:1362222</ref> <ref>PMID:1436517</ref> <ref>PMID:8352764</ref> <ref>PMID:8038017</ref> <ref>PMID:8257997</ref> <ref>PMID:8095302</ref> <ref>PMID:1997217</ref> <ref>PMID:8019560</ref> <ref>PMID:8081397</ref> <ref>PMID:7914929</ref> <ref>PMID:8133316</ref> <ref>PMID:7910950</ref> <ref>PMID:7655883</ref> <ref>PMID:7850982</ref> <ref>PMID:8579098</ref> <ref>PMID:9066351</ref> <ref>PMID:8990019</ref> <ref>PMID:9605286</ref> <ref>PMID:10036587</ref> <ref>PMID:10627135</ref> <ref>PMID:10694917</ref> <ref>PMID:10211412</ref> <ref>PMID:10439117</ref> <ref>PMID:10611950</ref> <ref>PMID:10071047</ref> <ref>PMID:10436378</ref> <ref>PMID:10842705</ref> <ref>PMID:10842718</ref> <ref>PMID:10882995</ref> <ref>PMID:11445644</ref> <ref>PMID:12557757</ref> <ref>PMID:11866053</ref> <ref>PMID:12050338</ref> <ref>PMID:12771253</ref> <ref>PMID:15214015</ref> <ref>PMID:15478468</ref> <ref>PMID:15217993</ref> <ref>PMID:17453626</ref> <ref>PMID:17577687</ref> <ref>PMID:17503405</ref> <ref>PMID:17635579</ref> Defects in TTR are a cause of hyperthyroxinemia dystransthyretinemic euthyroidal (HTDE) [MIM:[https://omim.org/entry/145680 145680].

ATTR amyloidosis is one of the worldwide most abundant forms of systemic amyloidosis. The disease is caused by the misfolding of transthyretin protein and the formation of amyloid deposits at different sites within the body. Here, we present a 2.97 A cryo electron microscopy structure of a fibril purified from the tissue of a patient with hereditary Val30Met ATTR amyloidosis. The fibril consists of a single protofilament that is formed from an N-terminal and a C-terminal fragment of transthyretin. Our structure provides insights into the mechanism of misfolding and implies the formation of an early fibril state from unfolded transthyretin molecules, which upon proteolysis converts into mature ATTR amyloid fibrils.
