Fibroblast transcriptomics in molecular diagnostics of a comprehensive dystonia cohort

The paper uses fibroblast RNA-seq to improve molecular diagnosis in dystonia patients by identifying RNA expression and splicing defects missed by genomic sequencing.

Biallelic variants in DAP3 result in reduced assembly of the mitoribosomal small subunit with altered intrinsic and extrinsic apoptosis and a Perrault syndrome-spectrum phenotype

This study identifies biallelic DAP3 variants causing mitoribosomal dysfunction, leading to combined oxidative phosphorylation deficiency and Perrault syndrome-like features.

Clinical implementation of RNA sequencing for Mendelian disease diagnostics

The paper implements RNA-seq in diagnostics for Mendelian diseases, achieving a 16% diagnosis rate in WES-inconclusive cases by detecting aberrant expression, splicing, and mono-allelic expression.

Diagnosing pediatric mitochondrial disease: lessons from 2,000 exomes

This study analyzes 2,023 pediatric exomes to diagnose mitochondrial disease, identifying 1,109 molecular diagnoses and 62 novel disease genes through exome sequencing and functional studies.

Integration of proteomics with genomics and transcriptomics increases the diagnostic rate of Mendelian disorders

Adding tandem mass tag proteomics to genome and transcriptome data resolved 22% of 121 unsolved suspected mitochondrial disease cases and surfaced two new disease genes.

Mutations in ELAC2 associated with hypertrophic cardiomyopathy impair mitochondrial tRNA 3’-end processing

This study identifies novel ELAC2 variants linked to hypertrophic cardiomyopathy and mitochondrial dysfunction, confirms their pathogenicity through in vitro analysis, and links one variant to prostate cancer.

OCR-Stats: Robust estimation and statistical testing of mitochondrial respiration activities using Seahorse XF Analyzer

This study develops OCR-Stats, a statistical method to improve the accuracy of mitochondrial respiration measurements from Seahorse XF Analyzer data by addressing noise and variation across plates and wells.

Genetic diagnosis of Mendelian disorders via RNA sequencing

This study uses RNA sequencing to identify genetic diagnoses in mitochondrial disease patients by detecting aberrant gene expression and splicing events.
