Both in health and lung disease, carriers of the amino acid methionine at codon 11 within the SFTPD gene show highest serum concentrations of SFTPD, but more importantly they exhibit a multimeric organization of SFTPD with an unrestricted lectin binding activity compared to counterparts carrying threonine at position 11 (42, 43). The gene discussed is SFTPD; the disease is lung disorder.
