Polymorphic genes
A gene is said to be polymorphic if more than one allele occupies that gene's locus within a population. In addition to having more than one allele at a specific locus, each allele must also occur in the population at a rate of at least 1% to generally be considered polymorphic. Gene polymorphisms can occur in any … See more A rule of thumb that is sometimes used is to classify genetic variants that occur below 1% allele frequency as mutations rather than polymorphisms. However, since polymorphisms may occur at low allele frequency, this … See more A polymorphism can be any sequence difference. Examples include: • Single nucleotide polymorphisms (SNPs) are a single … See more Polymorphisms can be identified in the laboratory using a variety of methods. Many methods employ PCR to amplify the sequence of a gene. Once amplified, polymorphisms and mutations in the sequence can be detected by DNA sequencing, … See more Lung cancer Polymorphisms have been discovered in multiple XPD exons.
