The phrase "aberrations may occur" is correct and usable in written English.
It can be used in contexts where you want to indicate that deviations or irregularities might happen, often in scientific, technical, or formal discussions.
Example: "In this experiment, we must consider that aberrations may occur due to environmental factors."
Alternatives: "anomalies may arise" or "irregularities could happen."
It is noteworthy that non-genetic aberrations may occur post-zygotically, resulting in a mosaic distribution.
Similar genomic aberrations may occur in DCIS and IDC to highlight possible similarities in protein expression [ 41, 42].
Although not a definite proof, clustering provides clues to which genetic aberrations may occur together in the same cells [ 11, 44].
In contrast, the null hypothesis maintains that sporadic aberrations may occur anywhere on the genome, but that no region is 'special'special
Although recent evidence suggests that some of these aberrations may occur subsequent to dissemination (Schmidt-Kittler et al, 2003), the fact that metastases are often clonal in nature (Fidler and Kripke, 1977) supports the hypothesis that there is a specific subpopulation within the heterogenous primary tumour that these cells originate from.
The accuracy of detecting chromosomal abnormalities by karyotyping, FISH, and PCR is generally high; however, these methods do not allow detection of all the aberrations that may occur [ 6].
Other genomic aberrations, including those giving rise to higher ploidy aberrations, may also occur at the same locus as the deletion or CNNLOH, further complicating the picture.
Because of the physical proximity to ErbB-2, copy number aberrations may also occur in the topoII α gene, which may be related to the altered chemosensitivity to topoII inhibitors (Jarvinen and Liu, 2006).
It is postulated here that when a growing OF has progressed past the priming region and its main portion has been synthesized, upon approaching its conclusion, the final elongation may take place in a region of the template where certain triplets are repeated: in that case a series of aberrations on the elongation mechanism may occur.
The results also suggest that there are aberrations in the purine pathway in PD which may occur upstream from uric acid.
Excess mtDNA replications and increased mtDNA copy number are regarded as an initial event of pathological mitochondrial genome alteration; they may occur as a compensatory mechanism for mtDNA aberrations and mitochondrial dysfunction.
