If a person has a certain variant at a certain position, the same person will probably also have other linked variants 10,000 or 50,000 bp nearby, and the same constellation will be found in several relatives of this person.
Along chromosome 19, there was a marked excess of invariant repeats compared to variant repeats at certain locations, particularly marked near the p terminus.
Already, directed evolution methods have been applied to create recombinase variants with activity at certain genomic sites which bear some resemblance to the target site of the original recombinase [7], [8].
Thus, if a research group has identified an interesting rare variant at a certain position of the genome, it can easily find out whether other centers have additional genomes with the variant in question.
Even though overall the total number of cHD SNPs surpasses the number of sequence variants for each chromosome (Suppl. Table S1), at certain positions in individual bins, WES has more variants as exemplified towards the end of chromosome 1 (Fig. 2(a)).
At low depths, variant allele frequencies can only occur at certain discrete levels, largely explaining the pattern in Figure 6.
Alternatively, recent theoretical studies demonstrate that rare variants may create spurious or synthetic associations at certain common alleles [ 32].
Besides established variants, we found certain unreported variants at sub-genome-wide level QKI, REEP3, TMCC2, FAM129C, FAM241B, and LOC100506207.
The enrichment in the frequency of certain genetic variants at this extremely old people probably reflects a selection effect that may enhance the likelihood of survival.
Genotypic variation of MTBC strains at various geographic settings and significant associations between certain allelic variants at VNTR loci, MTBC lineages, and spoligotyping families have been reported (7, 12 – 12 ).
