The percentage of NSCLC-specific MUC genetic changes from 0–28% (MUC1, 7%; MUC2, 7%; MUC3A, 2.5%; MUC3B, 0%; MUC4, 17%; MUC5AC, 0.5%; MUC5B, 11%; MUC6, 6%; MUC7, 3%; MUC8, 0.3%; MUC12, 4%; MUC13, 4%; MUC15, 1.2%; MUC16, 28%; MUC17, 14%; MUC19, 2.1%; MUC20, 14%; MUC21, 2.1%; MUC22, 1.4%; Figure 6(b)), and were mainly mutation, amplification, and deep deletion. Here, MUC21 is linked to non-small cell lung carcinoma.
