Different sets of primers have been shown to amplify different taxonomic groups due to sequence variation.
So far, scientists have found over 90 variants in this gene and sequence variations may account for up to 50% of nonsyndromic hearing loss.
Nevertheless, there is also considerable sequence variation at these two positions.
An association between the length of the gene and its sequence variation has been reported.
Other sequence variations are single base exchanges, deletions and insertions.
These two loci are highest sequence variation rate within human genome.
Based on sequence variation in the C-terminal region of the p72 gene 22 genotypes have been identified.
Yet, there is considerable sequence variation, particularly among the eukaryotic RNAs.
The sequence variation between the proteins is then associated with various viral serotypes.
Genetic disorders can be caused by any or all known types of sequence variation.
