RESULTS Sequence analysis of the proband’s DNA revealed two novel mutations, both located in exon 3 of the RAX gene. c.664delT frameshifting deletion generates a premature stop codon (p.Ser222ArgfsX62). c.909CG is a nonsense mutation, changing a tyrosine at position 303 to a stop codon (p.Tyr303X). ...

Genome evolution
Genome evolution is the process by which a genome changes in structure (sequence) or size over time. The study of genome evolution involves multiple fields such as structural analysis of the genome, the study of genomic parasites, gene and ancient genome duplications, polyploidy, and comparative genomics. Genome evolution is a constantly changing and evolving field due to the steadily growing number of sequenced genomes, both prokaryotic and eukaryotic, available to the scientific community and the public at large.
