Polymorphic genes
WebPolymorphisms of a number of DNA repair genes involved in several distinct pathways have been identified. However, their effects on repair function have not been well characterized. We demonstrated previously that DRC for removal of benzo[a]pyrene diol epoxide-induced DNA damage measured by a host-cell reactivation assay was modulated by two … 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. XPD refers to "xeroderma pigmentosum group D" and is involved in a See more

WebEighty seven individuals from 5 locations were screened using 4 highly polymorphic primers. A total of 173 polymorphic loci were detected out of 191 loci amplified. Small but significant genetic differentiation was detected between the Chinese and Japanese populations by both AMOVA and pairwise F ST analyses, which was further supported by cluster analysis.
