[[http://www.uniprot.org/uniprot/TTHY_HUMAN TTHY_HUMAN]] Defects in TTR are the cause of amyloidosis transthyretin-related (AMYL-TTR) [MIM:[http://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:[http://omim.org/entry/145680 145680]]. It is a condition characterized by elevation of total and free thyroxine in healthy, euthyroid persons without detectable binding protein abnormalities.<ref>PMID:1979335</ref>  Defects in TTR are a cause of carpal tunnel syndrome type 1 (CTS1) [MIM:[http://omim.org/entry/115430 115430]]. It is a condition characterized by entrapment of the median nerve within the carpal tunnel. Symptoms include burning pain and paresthesias involving the ventral surface of the hand and fingers which may radiate proximally. Impairment of sensation in the distribution of the median nerve and thenar muscle atrophy may occur. This condition may be associated with repetitive occupational trauma, wrist injuries, amyloid neuropathies, rheumatoid arthritis.<ref>PMID:8309582</ref> 

==Function==
[[http://www.uniprot.org/uniprot/TTHY_HUMAN TTHY_HUMAN]] Thyroid hormone-binding protein. Probably transports thyroxine from the bloodstream to the brain.<ref>PMID:3714052</ref>
