GC content shift is an evolutionary genome-wide change in the GC content of an organism. The evolutionary consequences of such a change is unknown. They are detected by comparing the genomes of two related organisms that share a recent common ancestor, and determining if their have different:
- AT/GC genomic composition
- High rate of synonymous mutations for syntenic gene pairs
- Amino acid usage frequencies
- Codon usage frequencies
