Multiple sequence alignment is a computational method for arranging DNA, RNA, or protein sequences so that homologous residues or nucleotides are placed in the same columns, enabling conservation analysis, motif detection, structure prediction, phylogenetic inference, and evolutionary interpretation. MSA accuracy depends on sequence similarity, length variation, insertions and deletions, domain architecture, sequence number, and algorithm choice; therefore, no single aligner is optimal for every dataset. Commonly used MSA tools include MAFFT, MUSCLE, Clustal Omega, and T-Coffee; MAFFT provides multiple strategies for diverse alignment problems, MUSCLE emphasizes speed and accuracy, Clustal Omega scales well to large protein datasets, and T-Coffee uses consistency information to improve alignment reliability. Unresolved issues include alignment uncertainty in divergent sequences, over-alignment of unrelated regions, variable effects of automated trimming, and propagation of alignment er

Breast cancer is a heterogeneous cancer, and it has been distinguished into four subtypes: luminal A, luminal B, HER2-positive and basal-like. Molecular mutations, epigenetic alterations, hormone exposure and immune microenvironment are related to the progression of breast cancer.
