Genome Sequencing for Diagnosing Rare Diseases
N Engl J Med. 2024 Jun 6;390(21):1985-1997. doi: 10.1056/NEJMoa2314761. ABSTRACT BACKGROUND: Genetic variants that cause rare disorders may remain elusive even after expansive testing, such as exome sequencing. The diagnostic yield of genome sequencing, particularly after a negative evaluation, remains poorly defined. METHODS: We sequenced and analyzed the genomes of families with diverse phenotypes who […]
Rapid Whole-Genome Sequencing and Clinical Management in the PICU: A Multicenter Cohort, 2016-2023
Pediatr Crit Care Med. 2024 Apr 26. doi: 10.1097/PCC.0000000000003522. Online ahead of print. ABSTRACT OBJECTIVES: Analysis of the clinical utility of rapid whole-genome sequencing (rWGS) outside of the neonatal period is lacking. We describe the use of rWGS in PICU and cardiovascular ICU (CICU) patients across four institutions. DESIGN: Ambidirectional multisite cohort study. SETTING: Four […]
Advancing access to genome sequencing for rare genetic disorders: recent progress and call to action
NPJ Genom Med. 2024 Mar 27;9(1):23. doi: 10.1038/s41525-024-00410-2. NO ABSTRACT PMID:38538605 | DOI:10.1038/s41525-024-00410-2
The contribution of de novo coding mutations to meningomyelocele
medRxiv, March 2, 2024. ABSTRACT Meningomyelocele (MM) is considered a genetically complex disease resulting from failure of neural tube closure (NTD). Patients display neuromotor disability and frequent hydrocephalus requiring ventricular shunting. A few proposed genes contribute to disease susceptibility, but most risk remains unexplained. We postulated that de novo mutations (DNMs) under purifying selection contribute […]
Rapid genomic sequencing for genetic disease diagnosis and therapy in intensive care units: a review
NPJ Genom Med. 2024 Feb 27;9(1):17. doi: 10.1038/s41525-024-00404-0. ABSTRACT Single locus (Mendelian) diseases are a leading cause of childhood hospitalization, intensive care unit (ICU) admission, mortality, and healthcare cost. Rapid genome sequencing (RGS), ultra-rapid genome sequencing (URGS), and rapid exome sequencing (RES) are diagnostic tests for genetic diseases for ICU patients. In 44 studies of […]
Evidence review and considerations for use of first line genome sequencing to diagnose rare genetic disorders
NPJ Genom Med. 2024 Feb 26;9(1):15. doi: 10.1038/s41525-024-00396-x. ABSTRACT Early use of genome sequencing (GS) in the diagnostic odyssey can reduce suffering and improve care, but questions remain about which patient populations are most amenable to GS as a first-line diagnostic test. To address this, the Medical Genome Initiative conducted a literature review to identify […]
Multi-center implementation of rapid whole genome sequencing provides additional evidence of its utility in the pediatric inpatient setting
Front Pediatr. 2024 Feb 19;12:1349519. doi: 10.3389/fped.2024.1349519. eCollection 2024. ABSTRACT OBJECTIVE: Multi-center implementation of rapid whole genome sequencing with assessment of the clinical utility of rapid whole genome sequencing (rWGS), including positive, negative and uncertain results, in admitted infants with a suspected genetic disease. STUDY DESIGN: rWGS tests were ordered at eight hospitals between November […]
Joint, multifaceted genomic analysis enables diagnosis of diverse, ultra-rare monogenic presentations
bioRxiv [Preprint]. 2024 Feb 16:2024.02.13.580158. doi: 10.1101/2024.02.13.580158. ABSTRACT Genomics for rare disease diagnosis has advanced at a rapid pace due to our ability to perform “N-of-1” analyses on individual patients. The increasing sizes of ultra-rare, “N-of-1” disease cohorts internationally newly enables cohort-wide analyses for new discoveries, but well-calibrated statistical genetics approaches for jointly analyzing these […]
Loss of symmetric cell division of apical neural progenitors drives DENND5A -related developmental and epileptic encephalopathy
medRxiv. 2024 Jan 31:2022.08.23.22278845. doi: 10.1101/2022.08.23.22278845. Preprint. ABSTRACT Developmental and epileptic encephalopathies (DEEs) are a heterogenous group of epilepsies in which altered brain development leads to developmental delay and seizures, with the epileptic activity further negatively impacting neurodevelopment. Identifying the underlying cause of DEEs is essential for progress toward precision therapies. Here we describe a […]
The Plasma Lipidomic Landscape in Patients with Sepsis due to Community-acquired Pneumonia
Am J Respir Crit Care Med. 2024 Jan 19. doi: 10.1164/rccm.202308-1321OC. Online ahead of print. ABSTRACT RATIONALE: The plasma lipidome has the potential to reflect many facets of the host status during severe infection. Previous work is limited to specific lipid groups, or focused on lipids as prognosticators. OBJECTIVES: To map the plasma lipidome during […]
