What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Homo sapiens (human)
Samples

Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Summary (written by the submitters)
Hotspot mutations in the spliceosome component genes have been recently reported at high frequency in hematological malignancies, suggesting the importance of this pathway in cancer. However, a comprehensive survey of splicing factor mutations across tumor types has not yet been performed.
Read the full summary ↓
We analyzed whole-exome sequencing data across 33 tumor types in The Cancer Genome Atlas (TCGA) in order to discover recurrent mutations in spliceosome components, identifying 119 genes with significant non-silent mutation patterns, including mutation overrepresentation, recurrent loss of function (tumor suppressor-like), or hotspot mutation profile (oncogene-like). We used RNA sequencing data to identify altered splicing events associated with these spliceosome mutations. In addition, we were able to discover common gene pathway profiles associated with the presence of these mutations. Our analysis suggests that somatic alteration of the splicing pathway is common in solid tumors and may represent an underappreciated hallmark of tumorigenesis.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE100530_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA392042 and SRA study SRP110582. Searching any of these in the dataset finder brings you back here.
