The phrase "alteration data" is correct and usable in written English.
It can be used in contexts where information about changes or modifications is being discussed, such as in data analysis or project management.
Example: "The alteration data provided by the team will help us understand the impact of the recent changes on the overall project timeline."
Alternatives: "modification data" or "change data".
For patients in each subgroup, we identified significantly altered genes against the remaining samples based on the network-smoothed alteration data by SAM (SAM significance analysis of microarrays was originally designed for identifying differentially expressed genes) [ 47].
One of the most successful approaches to discerning the signal in mutation data or in copy number alteration data is to seek out those genes or regions which are altered at a frequency above a background random model.
Sequence mutation and DNA copy number alteration data for all TCGA GBM cases was obtained from the TCGA data portal [48].
(1) More alteration data: the next phase of the TCGA GBM project will be sequencing over 6,000 gene and microRNA targets in several hundred additional GBM cases, as well as a number of tumor and paired normal complete genome sequences.
Approximately 90% of all ras mutations affect the K-ras gene, of which 85% occur in codon 12. K-ras mutations occur in particularly high frequency in adenocarcinoma (20 30%) but sequencing of k-ras and c-raf of our transgenic tumor model did not evidence any sequence alteration (data not shown).
GALNS gene alteration data were gathered from the primary reports.
The guanidinium chloride insoluble Alcian blue stained Muc2 band showed no alterations (data not shown).
Analysis of the M10 cells-derived metastatic MT10 and MG10 cells revealed the presence of identical gene alterations (data not shown).
The remaining 10 patients displayed H19DMR-GOM but did not show other causative alterations (data not shown).
Minimal cystic dilation was noted in rare glands, in the absence of any gland crowding or other cytologic alterations (data not shown).
We also found four F354L alterations (data not shown) but we did not consider these as missense mutations as this alteration has previously been reported to be a rare polymorphism of the gene (Launonen et al, 2000).
