Phenotypic screening models for rapid diagnosis of genetic variants and discovery of personalized therapeutics
Mol Aspects Med. 2022 Nov 18:101153. doi: 10.1016/j.mam.2022.101153. Online ahead of print. ABSTRACT Precision medicine strives for highly individualized treatments for disease under the notion that each individual’s unique genetic makeup and environmental exposures imprints upon them not only a disposition to illness, but also an optimal therapeutic approach. In the realm of rare disorders, […]
Rapid Whole Genome Sequencing in Critically Ill Neonates Enables Precision Medicine Pipeline
J Pers Med. 2022 Nov 18;12(11):1924. doi: 10.3390/jpm12111924. ABSTRACT Rapid genome sequencing in critically ill infants is increasingly identified as a crucial test for providing targeted and informed patient care. We report the outcomes of a pilot study wherein eight critically ill neonates received rapid whole genome sequencing with parental samples in an effort to […]
Biallelic PRMT7 pathogenic variants are associated with a recognizable syndromic neurodevelopmental disorder with short stature, obesity, and craniofacial and digital abnormalities
Genet Med. 2022 Nov 17:S1098-3600(22)00954-6. doi: 10.1016/j.gim.2022.09.016. Online ahead of print. ABSTRACT PURPOSE: Protein arginine methyltransferase 7 (PRMT7) is a member of a family of enzymes that catalyzes the methylation of arginine residues on several protein substrates. Biallelic pathogenic PRMT7 variants have previously been associated with a syndromic neurodevelopmental disorder characterized by short stature, brachydactyly, […]
Functional and clinical studies reveal pathophysiological complexity of CLCN4-related neurodevelopmental condition
Mol Psychiatry. 2022 Nov 16. doi: 10.1038/s41380-022-01852-9. Online ahead of print. ABSTRACT Missense and truncating variants in the X-chromosome-linked CLCN4 gene, resulting in reduced or complete loss-of-function (LOF) of the encoded chloride/proton exchanger ClC-4, were recently demonstrated to cause a neurocognitive phenotype in both males and females. Through international clinical matchmaking and interrogation of public […]
Evaluating human mutation databases for “treatability” using patient-customized therapy
Med (N Y). 2022 Nov 11;3(11):740-759. doi: 10.1016/j.medj.2022.08.006. ABSTRACT Genome sequencing in the clinic often allows patients to receive a molecular diagnosis. However, variants are most often evaluated for pathogenicity, neglecting potential treatability and thus often yielding limited clinical benefit. Antisense oligonucleotides (ASOs), among others, offer attractive programmable and relatively safe platforms for customized therapy […]
Brain monoamine vesicular transport disease caused by homozygous SLC18A2 variants: A study in 42 affected individuals
Genet Med. 2022 Oct 31:S1098-3600(22)00948-0. doi: 10.1016/j.gim.2022.09.010. Online ahead of print. ABSTRACT PURPOSE: Brain monoamine vesicular transport disease is an infantile-onset movement disorder that mimics cerebral palsy. In 2013, the homozygous SLC18A2 variant, p.Pro387Leu, was first reported as a cause of this rare disorder, and dopamine agonists were efficient for treating affected individuals from a […]
Autosomal recessive LRP1-related syndrome featuring cardiopulmonary dysfunction, bone dysmorphology, and corneal clouding
Cold Spring Harb Mol Case Stud. 2022 Oct 28;8(6):a006169. doi: 10.1101/mcs.a006169. Print 2022 Oct. ABSTRACT We provide the first study of two siblings with a novel autosomal recessive LRP1-related syndrome identified by rapid genome sequencing and overlapping multiple genetic models. The patients presented with respiratory distress, congenital heart defects, hypotonia, dysmorphology, and unique findings, including […]
N-myc mediated translation control is a therapeutic vulnerability in medulloblastoma
Cancer Res. 2022 Oct 20:CAN-22-0945. doi: 10.1158/0008-5472.CAN-22-0945. Online ahead of print. ABSTRACT Deregulation of N-myc is a leading cause of malignant brain tumors in children. To target N-myc-driven medulloblastoma, most research has focused on identifying genomic alterations or on the analysis of the medulloblastoma transcriptome. Here, we have broadly characterized the translatome of medulloblastoma and […]
Phenotypic continuum of NFU1-related disorders
Ann Clin Transl Neurol. 2022 Oct 18. doi: 10.1002/acn3.51679. Online ahead of print. ABSTRACT Bi-allelic variants in Iron-Sulfur Cluster Scaffold (NFU1) have previously been associated with multiple mitochondrial dysfunctions syndrome 1 (MMDS1) characterized by early-onset rapidly fatal leukoencephalopathy. We report 19 affected individuals from 10 independent families with ultra-rare bi-allelic NFU1 missense variants associated with […]
Safety and efficacy of intraventricular immunovirotherapy with oncolytic HSV-1 for CNS cancers
Clin Cancer Res. 2022 Oct 14:CCR-22-1382. doi: 10.1158/1078-0432.CCR-22-1382. Online ahead of print. ABSTRACT PURPOSE: Oncolytic virotherapy with herpes simplex virus-1 (HSV) has shown promise for treatment of pediatric and adult brain tumors; however, completed and ongoing clinical trials have utilized intratumoral/peritumoral oncolytic HSV (oHSV) inoculation due intraventricular/intrathecal toxicity concerns. Intratumoral delivery requires an invasive neurosurgical […]
