The F508del and S511A mutations generate different fragmentation fingerprints that are each unlike the wild-type; yet, both mutants generate new N-terminal-bearing CFTR fragments that are not observed with other CK2-related mutations (S511D, S422A/D and T1471A/D).
Similar behavioral results from two independent targeted gene mutations, generated with different targeting vectors, bred on different genetic backgrounds, and tested in different laboratory environments, corroborates the negative findings on sociability in oxytocin mutant mice.
While they resolved some of the previous limitations from TP53 studies (mostly by examining large portions of the human genome which are usually not under selection and which have a nucleotide context that is representative of the whole human genome) they still did not address the important issue of examining mixtures of mutations generated by different mutational processes.
The other two mutations (A73T and T155C) generated different amino acids (Table 1).
It was observed that, when translated into amino acids, all three mutations (T68C, T45G, and A405C) generated different amino acids (Table 2).
It shows how mutation could generate different amino acid sequences.
However, the fact that the JAK2+ syndromes exhibit various clinical features raises the question of how a single mutation can generate different MPNs and strongly suggests that other acquired events have to occur, at least in ET and PMF.
Different mutational processes generate different combinations of mutation types, termed 'signatures' (Nik-Zainal et al., 2012a).
By overexpressing C99 wildtype and C99 mutations, known to generate different Aβ42/Aβ40 levels [4], [5] in human neuroblastoma cells, we obtained information about the genome-wide gene regulation by using whole genome microarrays.
The team says if CRISPR is used in a gene therapy to edit billions of cells, bad results are "likely". "The multitude of different mutations generated makes it likely that one or more edited cells in each protocol would be endowed with an important pathogenic lesion," according to geneticist Allan Bradley, who headed the study, published in the journal Nature Biotechnology.
