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)
Topic
Acute myeloid leukemiaThis series is part of our curated briefing on it.
Samples
78 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)
Genomic profiles and prognostic biomarkers in patients with acute myeloid leukemia (AML) from ancestry diverse populations are underexplored. We analyzed the exomes and transcriptomes of 100 Black patients with AML (Alliance) and compared somatic mutation frequencies with those of 323 White patients (BeatAML). Seventy-three percent of 162 recurrent gene mutations identified in Black patients, including a novel PHIP alteration detected in 7% of patients, were found in only ≤1 White patient.

Black patients with myelodysplasia-related AML were younger than White patients suggesting intrinsic and/or extrinsic dysplasia-causing stressors. On multivariable outcome analyses of Black patients, NPM1 and NRAS mutations associated with inferior disease-free and IDH1/2 mutations with reduced overall survival. Inflammatory profiles, cell type distributions and transcriptional profiles differed between Black and White NPM1-mutated patients. Incorporation of ancestry-specific risk markers into the 2022 European LeukemiaNet genetic-risk stratification changed risk-group assignment for one-third of Black patients and improved their outcome prediction.

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 GSE266099_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 PRJNA1105881 and SRA study SRP504599. Searching any of these in the dataset finder brings you back here.

Study design
A cohort of 78 individual samples

The grouping that defines any comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Sample titles run Patid01 … Patid78 and carry no group information.
