Examples include: • Single nucleotide polymorphisms (SNPs) are a single nucleotide changes that happen in the genome in a particular location. The single nucleotide polymorphism is the most common form of genetic variation. • Small-scale insertions/deletions (Indels) consist of insertions or deletions of bases in DNA.
WebAn example of such a mutation was recently described in the Wilson's Disease (WD) gene, ATP7B; a 15-bp deletion in the promoter region of the gene was present on 60.5% of Sardinian WD chromosomes, and reduced transcriptional activity by 75% in expression assays. 59 Mutations can also change splicing patterns of a gene.
