Summary (written by the submitters)
Neurodevelopmental disorders (NDDs) are conditions that affect the development of the central nervous system, often identified during early childhood. These disorders include intellectual disability, communication disorders, autism spectrum disorders, and attention-deficit hyperactivity disorder (ADHD). Approximately 40% of NDDs are monogenic diseases, with at least 8% involving genes of the ubiquitin-proteasome system (UPS).

This conserved proteolytic system plays a key role in protein homeostasis by degrading ubiquitin-tagged proteins. Among monogenic pathologies linked to the UPS, genetic variations directly affecting the 26S proteasome define a new subclass of NDDs known as neurodevelopmental proteasomopathies. The submitted data originate from an exhaustive study on several unique variants identified in the PSMC5 gene, which encodes the AAA-ATPase subunit PSMC5/Rpt6 of the 26S proteasome. Functional analyses conducted in this study revealed that these alterations lead to a loss of proteasome function, triggering a complex cellular program involving an inflammatory response and innate immunity remodeling. To further investigate these observations, gene expression was analyzed using NanoString on an autoimmune gene panel, revealing a type I interferon signature in the patients. These results were confirmed by 3'seq-RNA Profiling (3'SRP), which showed strong overexpression of genes in the type I interferon pathway, accompanied by transcriptional dysregulation involving alterations in innate immunity and inflammatory processes. The provided data thus confirm the central role of PSMC5 gene alterations in the pathogenesis of neurodevelopmental proteasomopathies.

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 GSE288665_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 PRJNA1218815 and SRA study SRP561358. Searching any of these in the dataset finder brings you back here.
