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.

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)
Myotonic dystrophy type 1 (DM1) is the most common form of adult-onset muscular dystrophy caused by expansion of a CTG repeat microsatellite within DMPK. In 10-20% of individuals with DM1, symptomatic onset begins at birth; these patients are classified as congenital myotonic dystrophy (CDM). While dysregulation of RNA metabolism, specifically alternative splicing, has been linked to disease pathology in adult-onset DM1, little is known about the mechanism of CDM.
Read the full summary ↓
Biopsies from individuals (CDM), age range 0.04-16 years, were subjected to total RNA-seq to quantify the transcriptomic dysregulation throughout pediatric development. To achieve this, they were compared against age matched pediatric controls which revealed a triphasic pattern of dysregulation not before seen observed in CDM. CDM samples were also compared to adult-onset (DM1) individuals which showcased a shared disease signature to seen in all individuals with myotonic dystrophy irrespective of disease age of onset.

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 GSE201255_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 PRJNA830511 and SRA study SRP371576. Searching any of these in the dataset finder brings you back here.
