Entrez ID 7276
Gene name Transthyretin
Gene symbol TTR
Synonyms (NCBI Gene)
ATTRCTSCTS1HEL111HsT2651PALBTBPATTN
Chromosome 18
Chromosome location 18q12.1
Summary This gene encodes one of the three prealbumins, which include alpha-1-antitrypsin, transthyretin and orosomucoid. The encoded protein, transthyretin, is a homo-tetrameric carrier protein, which transports thyroid hormones in the plasma and cerebrospinal f
