Sentence examples for variation at site from inspiring English sources

In contrast, genetic variation at site −592 resulted in no association in other study analyzing the impact of these polymorphisms on the risk of HAM/TSP in Brazilian patients [ 20].

It should be mentioned that although the validity of M9a1a might be questionable because this haplogroup was defined solely by a control region variation at site 16316, its two major clades (M9a1a1 and M9a1a2) were determined by additional coding region variants.

This is particularly true of mammalian SWS1 pigments where the variation at site 86 is better characterized: in most mammalian pigments the presence of F86 dramatically shifts λmax, into the UV [ 16, 19, 29, 30], but this is not always the case [ 23].

The mismatch rate δ i = β i + ε i may be decomposed into biological and technical variation, where ε i denotes the technical error that accumulated during the preparation, sequencing and alignment steps and β i denotes the biological nucleotide variation at site i.

In the region of overlap between the two studies, we failed to detect variation at site -339, where there is a minor allele deletion of a single nucleotide with frequency 3.6% in British army recruits, and identified two additional variants at sites -360 and -352 with minor allele frequencies 2.8%and1.2%2%, respectively.

b Color variation at Sites U1426 and U1427 over the past 1.0 Myr.

Copy number variation of these genes is therefore unlikely to underlie the salt-sensitive hypertension that is prevalent in the indigenous Southern African populations (although it is interesting to note that the heatmaps generated for the genes AGTR1 and INS do show evidence of population-specific variation at sites within the genes - see supplementary data file S6).

Data are insufficient to systematically analyze variation at sites.

Extensive sequence variation at sites where antigen recognition occurs is a typical feature of the MHC [ 8].

However, amino acid variation at sites under positive selection did not differentiate before and after vaccine introduction in G1P[8] strains identified in either Belgian or Australian strains.

These data suggest that sequence variation at sites under positive selection in multiple VPs may be involved in immune escape of circulating G1P[8] strains.
