Heteromeric clusters of ubiquitinated ER-shaping proteins drive ER-phagy
Nature. 2023 May 24. doi: 10.1038/s41586-023-06090-9. Online ahead of print. ABSTRACT Membrane-shaping proteins characterized by reticulon homology domains play an important part in the dynamic remodelling of the endoplasmic reticulum (ER). An example of such a protein is FAM134B, which can bind LC3 proteins and mediate the degradation of ER sheets through selective autophagy (ER-phagy)1. […]
AMFR dysfunction causes autosomal recessive spastic paraplegia in human that is amenable to statin treatment in a preclinical model
Acta Neuropathol. 2023 Apr 29. doi: 10.1007/s00401-023-02579-9. Online ahead of print. ABSTRACT Hereditary spastic paraplegias (HSP) are rare, inherited neurodegenerative or neurodevelopmental disorders that mainly present with lower limb spasticity and muscle weakness due to motor neuron dysfunction. Whole genome sequencing identified bi-allelic truncating variants in AMFR, encoding a RING-H2 finger E3 ubiquitin ligase anchored […]
The genomic landscape of familial glioma
Sci Adv. 2023 Apr 28;9(17):eade2675. doi: 10.1126/sciadv.ade2675. Epub 2023 Apr 28. ABSTRACT Glioma is a rare brain tumor with a poor prognosis. Familial glioma is a subset of glioma with a strong genetic predisposition that accounts for approximately 5% of glioma cases. We performed whole-genome sequencing on an exploratory cohort of 203 individuals from 189 […]
ARF1-related disorder: phenotypic and molecular spectrum
J Med Genet. 2023 Apr 25:jmg-2022-108803. doi: 10.1136/jmg-2022-108803. Online ahead of print. ABSTRACT PURPOSE: ARF1 was previously implicated in periventricular nodular heterotopia (PVNH) in only five individuals and systematic clinical characterisation was not available. The aim of this study is to provide a comprehensive description of the phenotypic and genotypic spectrum of ARF1-related neurodevelopmental disorder. […]
3D genome mapping identifies subgroup-specific chromosome conformations and tumor-dependency genes in ependymoma
Nat Commun. 2023 Apr 21;14(1):2300. doi: 10.1038/s41467-023-38044-0. ABSTRACT Ependymoma is a tumor of the brain or spinal cord. The two most common and aggressive molecular groups of ependymoma are the supratentorial ZFTA-fusion associated and the posterior fossa ependymoma group A. In both groups, tumors occur mainly in young children and frequently recur after treatment. Although […]
Clinical and molecular spectrum of a large Egyptian cohort with ALS2-related disorders of infantile-onset of clinical continuum IAHSP/JPLS
Clin Genet. 2023 Apr 13. doi: 10.1111/cge.14338. Online ahead of print. ABSTRACT This study presents 46 patients from 23 unrelated Egyptian families with ALS2-related disorders without evidence of lower motor neuron involvement. Age at onset ranged from 10 months to 2.5 years, featuring progressive upper motor neuron signs. Detailed clinical phenotypes demonstrated inter- and intrafamilial […]
Rapid Whole Genome Sequencing for Diagnosis of Single Locus Genetic Diseases in Critically Ill Children
Methods Mol Biol. 2023;2621:217-239. doi: 10.1007/978-1-0716-2950-5_12. ABSTRACT Upon admission to intensive care units (ICU), the differential diagnosis of almost all infants with diseases of unclear etiology includes single locus genetic diseases. Rapid whole genome sequencing (rWGS), including sample preparation, short-read sequencing-by-synthesis, informatics pipelining, and semiautomated interpretation, can now identify nucleotide and structural variants associated with […]
Isolated Absent Aortic Valves: A Unique Fetal Case With Echocardiographic, Pathologic, and Genetic Correlation
JACC Case Rep. 2023 Feb 22;11:101790. doi: 10.1016/j.jaccas.2023.101790. eCollection 2023 Apr 5. ABSTRACT We present a 22-week fetus with isolated absent aortic valve and inverse circular shunt. The pregnancy was interrupted. Here, echocardiography and pathology images demonstrate this rare entity. Whole genome sequencing revealed a potentially disease-causing variant in the APC gene. Whole genome sequencing […]
Transitional Care for Young People with Movement Disorders: Consensus-Based Recommendations from the MDS Task Force on Pediatrics
Mov Disord Clin Pract. 2023 Apr 4;10(5):748-755. doi: 10.1002/mdc3.13728. eCollection 2023 May. ABSTRACT BACKGROUND: The International Parkinson and Movement Disorders Society (MDS) set up a working group on pediatric movement disorders (MDS Task Force on Pediatrics) to generate recommendations to guide the transition process from pediatrics to adult health care systems in patients with childhood-onset […]
Automated prioritization of sick newborns for whole genome sequencing using clinical natural language processing and machine learning
Genome Med. 2023 Mar 16;15(1):18. doi: 10.1186/s13073-023-01166-7. ABSTRACT BACKGROUND: Rapidly and efficiently identifying critically ill infants for whole genome sequencing (WGS) is a costly and challenging task currently performed by scarce, highly trained experts and is a major bottleneck for application of WGS in the NICU. There is a dire need for automated means to […]
