1. A method of reducing cholesterol level or maintaining previously reduced cholesterol level in a human in need thereof comprising
a. selecting a human comprising
a nucleotide sequence encoding a proprotein convertase subtilisin/kexin type 9 (PCSK9) that comprises a C-terminal domain comprising a mutation E670G in SEQ ID NO: 1; and b. administering to said human an antibody or antibody fragment that specifically binds a PCSK9 amino acid sequence encoded by said nucleotide sequence comprised by the human, wherein the antibody comprises a VH domain derived from the recombination of a human VH segment, a human D gene segment and a human JH segment, the human VH segment encoding the framework 1 of SEQ ID NO: 40 and wherein said human comprises a VH gene segment encoding the framework 1 of SEQ ID NO: 40.
