El-Hattab-Alkuraya syndrome caused by biallelic WDR45B pathogenic variants: further delineation of the phenotype and genotype
Clin Genet. 2022 Mar 23. doi: 10.1111/cge.14132. Online ahead of print. ABSTRACT Homozygous pathogenic variants in WDR45B were first identified in six subjects from three unrelated families with global development delay, refractory seizures, spastic quadriplegia, and brain malformations. Since the initial report in 2018, no further cases have been described. In this report, we present […]
Healthcare Professionals’ Attitudes toward Rapid Whole Genome Sequencing in Pediatric Acute Care
Children. 2022; 9(3):357. Abstract We aimed to characterize knowledge and attitudes about rapid whole genome sequencing (rWGS) implementation of a broad constituency of healthcare professionals at hospitals participating in a statewide initiative to implement rWGS for hospitalized neonates and children up to 18 years of age meeting clinical criteria for testing. We surveyed 307 healthcare […]
Conventional Therapies Deplete Brain-Infiltrating Adaptive Immune Cells in a Mouse Model of Group 3 Medulloblastoma Implicating Myeloid Cells as Favorable Immunotherapy Targets
Front Immunol. 2022 Mar 3;13:837013. doi: 10.3389/fimmu.2022.837013. eCollection 2022. ABSTRACT Medulloblastoma is the most common childhood brain cancer. Mainstay treatments of radiation and chemotherapy have not changed in decades and new treatment approaches are crucial for the improvement of clinical outcomes. To date, immunotherapies for medulloblastoma have been unsuccessful, and studies investigating the immune microenvironment […]
Consolidation of the clinical and genetic definition of a SOX4-related neurodevelopmental syndrome
J Med Genet. 2022 Mar 1:jmedgenet-2021-108375. doi: 10.1136/jmedgenet-2021-108375. Epub ahead of print. PMID: 35232796. Abstract Background: A neurodevelopmental syndrome was recently reported in four patients with SOX4 heterozygous missense variants in the high-mobility-group (HMG) DNA-binding domain. The present study aimed to consolidate clinical and genetic knowledge of this syndrome. Methods: We newly identified 17 patients with SOX4 variants, predicted variant pathogenicity […]
Autosomal Recessive Cerebellar Atrophy and Spastic Ataxia in Patients With Pathogenic Biallelic Variants in GEMIN5
Front Cell Dev Biol. 2022 Feb 28;10:783762. doi: 10.3389/fcell.2022.783762. eCollection 2022. ABSTRACT The hereditary ataxias are a heterogenous group of disorders with an increasing number of causative genes being described. Due to the clinical and genetic heterogeneity seen in these conditions, the majority of such individuals endure a diagnostic odyssey or remain undiagnosed. Defining the […]

ABSTRACT The start of 2022 is an inflection point in the development of diagnostics and treatments for rare genetic diseases in prenatal, pediatric, and adult individuals; the theme of this special issue. Here I briefly review recent developments in the […]
Activated phosphoinositide 3-kinase δ syndrome associated with nephromegaly, growth hormone deficiency, bronchiectasis: a case report
Allergy Asthma Clin Immunol. 2022 Feb 21;18(1):15. doi: 10.1186/s13223-022-00655-5. ABSTRACT BACKGROUND: Activated phosphoinositide 3-kinase (PI3K) δ syndrome (APDS) is a rare form of primary immunodeficiency with 243 known cases reported in the literature. Known findings associated with the condition include recurrent sinusitis and bronchitis, bronchiectasis, immune cytopenias, mild developmental delay, splenomegaly, and lymphadenopathy. We report […]
Retrospective identification of prenatal fetal anomalies associated with diagnostic neonatal genomic sequencing results
Prenat Diagn. 2022 Feb 9. doi: 10.1002/pd.6111. Online ahead of print. ABSTRACT OBJECTIVE: To determine which types of fetal anomalies are associated with postnatal diagnoses of genetic diseases by genomic sequencing and to assess how prenatal genomic sequencing could affect clinical management. METHOD: This was a secondary analysis of the second Newborn Sequencing in Genomic […]
Evaluating use of changing technologies for rapid next-generation sequencing in pediatrics
Pediatr Res. 2022 Feb 3. doi: 10.1038/s41390-022-01965-5. Online ahead of print. ABSTRACT BACKGROUND: Rapid next-generation sequencing (NGS) offers the potential to shorten the diagnostic process and improve the care of acutely ill children. The goal of this study was to report our findings, including benefits and limitations, of a targeted NGS panel and rapid genome […]
Oligonucleotide correction of an intronic TIMMDC1 variant in cells of patients with severe neurodegenerative disorder
NPJ Genom Med. 2022 Jan 28;7(1):9. doi: 10.1038/s41525-021-00277-7. ABSTRACT TIMMDC1 encodes the Translocase of Inner Mitochondrial Membrane Domain-Containing protein 1 (TIMMDC1) subunit of complex I of the electron transport chain responsible for ATP production. We studied a consanguineous family with two affected children, now deceased, who presented with failure to thrive in the early postnatal […]
