WebThey are classified into families and subfamilies on the basis of the degree of amino acid similarity. Cytochrome P450 isoenzymes are regulated by both genetic and environmental factors. Of particular interest is genetic polymorphism in drug oxidation. Two genetic polymorphisms in drug oxidation are well known, the sparteine/debrisoquine ... WebStructural variation. This is a large (greater than 50 base pairs) rearrangement of part of the genome, and can be a deletion, duplication, insertion, inversion, translocation or often a combination of these. A copy number variation (CNV) is a duplication or deletion that changes the number of copies of a particular DNA segment within the genome.

WebThe mephenytoin polymorphism affects the metabolism of mephenytoin and several other drugs. Two mutant alleles of CYP2C19 have so far been identified to cause this polymorphism. These polymorphisms show recessive transmission of the poor or slow metabolizer phenotype, i.e. two mutant alleles define the genotype in these individuals. WebGenetic Conditions.

WebGenetic polymorphism is actively and steadily maintained in populations by natural selection, in contrast to transient polymorphisms where a form is progressively replaced by another. [16] :6-7 By definition, genetic polymorphism relates to a balance or equilibrium between morphs.
WebIn contrast, a polymorphism is a DNA sequence variation that is common in the population. In this case no single allele is regarded as the standard sequence. Instead there are two or more equally acceptable alternatives. The arbitrary cut-off point between a mutation and a polymorphism is 1 per cent.
