Gene polymorphic
Did you know?
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 … 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, … See more Lung cancer Polymorphisms have been discovered in multiple XPD exons.
