Gene: TTR (transthyretin) Homo sapiens
Symbol: TTR
Name: transthyretin
Description: Exhibits identical protein binding activity. Predicted to be involved in purine nucleobase metabolic process. Localizes to the extracellular exosome. Implicated in Alzheimer's disease; amyloidosis; carpal tunnel syndrome; dystransthyretinemic hyperthyroxinemia; and transthyretin amyloidosis.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ATTR; carpal tunnel syndrome 1; CTS; CTS1; epididymis luminal protein 111; HEL111; HsT2651; PALB; prealbumin, amyloidosis type I; TBPA; thyroxine-binding prealbumin; transthyretin (prealbumin, amyloidosis type I)
