In addition, using sgRNAs targeting two separate sites in the Mecp2 gene, we produced mice harboring the predicted deletions of about 700 bps.
There was a deletion of about 250 bp in the ndhG gene of the Beallara species.
Amongst the several hundred genes identified as being bound only in the high-activity ChIP experiment the number of genes whose expression is affected by leu3 deletion is about twice as great as the number expected by chance (p < 1e-3 for the null model being no enrichment of leu3Δ-affected genes).
Interestingly, the fragment 2 sequence obtained from the mosquito Plasmodium sample showed a rather different size, presenting a region with a large deletion (about a third of the amplified sequence), but was highly conserved in its sequence when compared to sequences found in human isolates of the same region, indicating a likely recombination event in this hotspot region.
Alignment of VRN-1 sequence from accessions TRI 17072 and TRI 17062 of T. boeoticum (spring and winter types, respectively) showed that the first accession had a mutation that has not been described previously, the substitution T → C coupled with 1 bp deletion about 200 bp downstream from the start of intron 1.
However, the blog post asserts that there was no evidence to support the allegations about a specific engineer and code deletions or about the general cultural environment at GitHub.
During its attenuation, MVA acquired large genomic deletions totalling about 30 kb, resulting in the complete loss of 26 open reading frames (ORFs), together with truncation or fragmentation of a further 21 ORFs and numerous smaller scale mutations [5].
Whereas the overall density of affirmed non-hotspot deletions was about the same in the other cohorts as for ADHD (with the exception of SZ which was about 50% higher; ref 4 and our results not shown), we again observed clustering in the same regions as in the ADHD trios, indicating that the clustering effect was not limited to this cohort (Table 1).
The deletion rate was about 0.3% per coupling.
The flanking DNA fragments, which were assigned to the mouse chromosome 10D1 region, were separated by about 7.2 kb, indicating that integration of the transgene resulted in the deletion of about 7.2 kb of the genome at the insertion site (Figure 2B).
