Ther Adv Rare Dis. 2024 Jul 31;5:26330040241263972. doi: 10.1177/26330040241263972. eCollection 2024 Jan-Dec. ABSTRACT TESS Research Foundation (TESS) is a patient-led nonprofit organization seeking to understand the basic biology and clinical impact of pathogenic variants in the SLC13A5 gene. TESS aims to improve the fundamental understanding of citrate’s role in the brain, and ultimately identify treatments […]
MSL2 variants lead to a neurodevelopmental syndrome with lack of coordination, epilepsy, specific dysmorphisms, and a distinct episignature
Am J Hum Genet. 2024 May 28:S0002-9297(24)00164-2. doi: 10.1016/j.ajhg.2024.05.001. Online ahead of print. ABSTRACT Epigenetic dysregulation has emerged as an important etiological mechanism of neurodevelopmental disorders (NDDs). Pathogenic variation in epigenetic regulators can impair deposition of histone post-translational modifications leading to aberrant spatiotemporal gene expression during neurodevelopment. The male-specific lethal (MSL) complex is a prominent […]
Biallelic Loss of Function Variants in SENP7 Cause Immunodeficiency with Neurologic and Muscular Phenotypes
J Pediatr. 2024 Jul 4:114180. doi: 10.1016/j.jpeds.2024.114180. Online ahead of print. ABSTRACT To evaluate a novel candidate disease gene, we engaged international collaborators and identified rare, biallelic, specifically homozygous, loss of function variants in SENP7 in four children from three unrelated families presenting with neurodevelopmental abnormalities, dysmorphism, and immunodeficiency. Their clinical presentations were characterized by […]
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 […]
Frontiers in congenital disorders of glycosylation consortium, a cross-sectional study report at year 5 of 280 individuals in the natural history cohort
Mol Genet Metab. 2024 Jun 6;142(4):108509. doi: 10.1016/j.ymgme.2024.108509. Online ahead of print. ABSTRACT OBJECTIVE: Our report describes clinical, genetic, and biochemical features of participants with a molecularly confirmed congenital disorder of glycosylation (CDG) enrolled in the Frontiers in Congenital Disorders of Glycosylation (FCDGC) Natural History cohort at year 5 of the study. METHODS: We enrolled […]
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 […]
