[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].

== Publication Abstract from PubMed ==
 +
Transthyretin (TTR) is a homotetrameric serum protein associated with amyloidoses such as familial amyloid polyneuropathy and senile systemic amyloidosis. The amyloid fibril formation of TTR can be inhibited through stabilization of the TTR tetramer by the binding of small molecules. In this study, we examined the inhibitory potency of caffeic acid phenethyl ester (CAPE) and its derivatives. Thioflavin T assay showed that CAPE suppressed the amyloid fibril formation of TTR. Comparative analysis of the inhibitory potencies revealed that phenethyl ferulate was the most potent among the CAPE derivatives. The binding of phenethyl ferulate and the selected compounds to TTR were confirmed by the 8-anilino-1-naphthalenesulfonic acid displacement and X-ray crystallography. It was also demonstrated that Bio 30, which is a CAPE-rich commercially available New Zealand propolis, inhibited TTR amyloidogenesis and stabilized the TTR tetramer. These results suggested that a propolis may be efficient for preventing TTR amyloidosis.
