Gene Expression Profiling Journals

A gene is said to be polymorphic if there is more than one allele occupying the locus of that gene within a population. In addition to having more than one allele at a particular site, each allele must also be considered polymorphic in the population at a rate of at least 1 per cent. Gene polymorphisms may be present in any region of the genome. Most polymorphisms are silent, meaning that they don't change the function or expression of a gene.

A polymorphic gene variant may lead to the production of an abnormal form of the protein or abnormal expression; this condition is associated with the disease.

In the laboratory, polymorphisms may be identified using a variety of methods. Many methods use PCR to boost a gene sequence
