Exome sequencing for disease research

Exome sequencing in amyotrophic lateral sclerosis implicates a novel gene, DNAJC7 encoding a heat-shock protein

Farhan SMK, et al. Nat Neurosci. 2019 Nov 25. 22: 1966–1974. PMCID: PMC6919277.

In this study, completed when the HudsonAlpha Discovery lab was still the HudsonAlpha Institute Genomic Services Lab, our exome sequencing services contributed to a larger, multi-center effort aimed at uncovering novel genes involved in amyotrophic lateral sclerosis (ALS), a neurodegenerative disease. The total number of exomes sequenced by all centers was 11,703—3,864 ALS patients and 7,839 ancestry-matched controls.

Their findings: “We observed a significant excess of rare protein-truncating variants among ALS cases, which was concentrated in constrained genes,”1 including DNAJC7, a heat shock protein 40 (HSP40) family member.

The significance of this work: Through exome sequencing of a large cohort of patients and ancestry-matched controls, the authors identified a novel gene involved in ALS as well as an unexpected excess of protein-truncating variants.
