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 […]
Differential newborn DNA methylation among individuals with complex congenital heart defects and childhood lymphoma
Birth Defects Res. 2022 Oct 13. doi: 10.1002/bdr2.2105. Online ahead of print. ABSTRACT BACKGROUND: There is emerging evidence that children with complex congenital heart defects (CHDs) are at increased risk for childhood lymphoma, but the mechanisms underlying this association are unclear. Thus, we sought to evaluate the role of DNA methylation patterns on “CHD-lymphoma” associations. […]
Dormant SOX9-positive cells facilitate MYC-driven recurrence of medulloblastoma
Cancer Res. 2022 Oct 11:CAN-22-2108. doi: 10.1158/0008-5472.CAN-22-2108. Online ahead of print. ABSTRACT Relapse is the leading cause of death in patients with medulloblastoma, the most common malignant pediatric brain tumor. A better understanding of the mechanisms underlying recurrence could lead to more effective therapies for targeting tumor relapses. Here, we observed that SOX9, a transcription […]
Dispatches from Biotech beginning BeginNGS: Rapid newborn genome sequencing to end the diagnostic and therapeutic odyssey
Am J Med Genet C Semin Med Genet. 2022 Oct 11. doi: 10.1002/ajmg.c.32005. Online ahead of print. ABSTRACT In this Dispatch from Biotech, we briefly review the urgent need for extensive expansion of newborn screening (NBS) by genomic sequencing, and the reasons why early attempts had limited success. During the next decade transformative developments will […]
Approaches to long-read sequencing in a clinical setting to improve diagnostic rate
Sci Rep. 2022 Oct 9;12(1):16945. doi: 10.1038/s41598-022-20113-x. ABSTRACT Over the past decade, advances in genetic testing, particularly the advent of next-generation sequencing, have led to a paradigm shift in the diagnosis of molecular diseases and disorders. Despite our present collective ability to interrogate more than 90% of the human genome, portions of the genome have […]
