The method of claim 5, wherein the aqueous solution consists of water and the compound, and the transthyretin amyloidosis is familial amyloid polyneuropathy (FAP) or familial amyloid cardiopathy (FAC). 14. The method of claim 6, wherein the aqueous solution consists of water and the compound, and the transthyretin amyloidosis is familial amyloid polyneuropathy (FAP) or familial amyloid cardiopathy (FAC). 15. The method of claim 7, wherein the aqueous solution consists of water and the compound, and the transthyretin amyloidosis is familial amyloid polyneuropathy (FAP) or familial amyloid cardiopathy (FAC). 16. The method of claim 8, wherein the aqueous solution consists of water and the compound, and the transthyretin amyloidosis is familial amyloid polyneuropathy (FAP) or familial amyloid cardiopathy (FAC). 17. A method comprising administering to an individual having transthyretin amyloidosis a tolerable amount of a compound comprising a single-stranded modified oligonucleotide consisting of 20 linked nucleosides having a nucleobase sequence consisting of SEQ ID NO: 80, wherein administering the tolerable amount of the compound increases plasma alanine transaminase (ALT) or aspartate transaminase (AST) levels in the individual by less than 4-fold and the modified oligonucleotide comprises: a gap segment consisting of ten linked deoxynucleosides; a 5' wing segment consisting of five linked nucleosides; and a 3' wing segment consisting of five linked nucleosides; wherein the gap segment is positioned between the 5' wing segment and the 3' wing segment, wherein each nucleoside of each wing segment comprises a 2'-O-methoxyethyl sugar, wherein each internucleoside linkage is a phosphorothioate linkage; and wherein each cytosine of the modified oligonucleotide is a 5-methylcytosine. 18. The method of claim 17, wherein the administering the tolerable amount of the compound increases plasma ALT or AST levels in the individual by less than 3-fold in the individual. 19.
