Discriminating Bacterial and Viral Infection Using a Rapid Host Gene Expression Test
Crit Care Med. 2021 Apr 28. doi: 10.1097/CCM.0000000000005085. Online ahead of print. ABSTRACT OBJECTIVES: Host gene expression signatures discriminate bacterial and viral infection but have not been translated to a clinical test platform. This study enrolled an independent cohort of patients to describe and validate a first-in-class host response bacterial/viral test. DESIGN: Subjects were recruited […]
Expanding the genotypic spectrum of ACTG2-related visceral myopathy
Cold Spring Harb Mol Case Stud. 2021 Apr 21:mcs.a006085. doi: 10.1101/mcs.a006085. Online ahead of print. ABSTRACT Visceral myopathies (VMs) encompass a spectrum of disorders characterized by chronic disruption of gastrointestinal function, with or without urinary system involvement. Pathogenic missense variation in smooth muscle gamma-actin gene (ACTG2) is associated with autosomal dominant VM. Whole genome sequencing […]
Rapid whole genome sequencing impacts care and resource utilization in infants with congenital heart disease
NPJ Genom Med. 2021 Apr 22;6(1):29. doi: 10.1038/s41525-021-00192-x. ABSTRACT Congenital heart disease (CHD) is the most common congenital anomaly and a major cause of infant morbidity and mortality. While morbidity and mortality are highest in infants with underlying genetic conditions, molecular diagnoses are ascertained in only ~20% of cases using widely adopted genetic tests. Furthermore, […]
Rare deleterious mutations of HNRNP genes result in shared neurodevelopmental disorders
Madelyn A Gillentine Genome Med. 2021 Apr 19;13(1):63. doi: 10.1186/s13073-021-00870-6. ABSTRACT BACKGROUND: With the increasing number of genomic sequencing studies, hundreds of genes have been implicated in neurodevelopmental disorders (NDDs). The rate of gene discovery far outpaces our understanding of genotype-phenotype correlations, with clinical characterization remaining a bottleneck for understanding NDDs. Most disease-associated Mendelian genes […]
Abnormal SCID Newborn Screening and Spontaneous Recovery Associated with a Novel Haploinsufficiency IKZF1 Mutation
J Clin Immunol. 2021 Apr 14. doi: 10.1007/s10875-021-01035-1. Online ahead of print. ABSTRACT PURPOSE: IKAROS, encoded by IKZF1, is a member of the IKAROS family of zinc-finger transcription factors playing critical roles in lymphocyte development, differentiation, and tumor suppression. Several studies demonstrated that IKZF1 mutations affecting DNA binding or homo-/hetero-dimerization are mostly associated with common […]
Biallelic hypomorphic mutations in HEATR5B, encoding HEAT repeat-containing protein 5B, in a neurological syndrome with pontocerebellar hypoplasia
Eur J Hum Genet. 2021 Apr 6. doi: 10.1038/s41431-021-00832-x. Online ahead of print. ABSTRACT HEAT repeats are 37-47 amino acid flexible tandem repeat structural motifs occurring in a wide variety of eukaryotic proteins with diverse functions. Due to their ability to undergo elastic conformational changes, they often serve as scaffolds at sites of protein interactions. […]
Comprehensive identification of somatic nucleotide variants in human brain tissue
Genome Biol. 2021 Mar 29;22(1):92. doi: 10.1186/s13059-021-02285-3. ABSTRACT BACKGROUND: Post-zygotic mutations incurred during DNA replication, DNA repair, and other cellular processes lead to somatic mosaicism. Somatic mosaicism is an established cause of various diseases, including cancers. However, detecting mosaic variants in DNA from non-cancerous somatic tissues poses significant challenges, particularly if the variants only are […]
Metagenomic Next-Generation Sequencing for Pathogen Detection and Transcriptomic Analysis in Pediatric Central Nervous System Infections
Open Forum Infect Dis. 2021 Mar 6;8(6):ofab104. doi: 10.1093/ofid/ofab104. eCollection 2021 Jun. ABSTRACT BACKGROUND: Pediatric central nervous system (CNS) infections are potentially life-threatening and may incur significant morbidity. Identifying a pathogen is important, both in terms of guiding therapeutic management and in characterizing prognosis. Usual care testing by culture and polymerase chain reaction is often […]
Correction to: De novo variants in SNAP25 cause an early-onset developmental and epileptic encephalopathy
Genet Med. 2021 Mar 8. doi: 10.1038/s41436-020-01090-w. Online ahead of print. PMID:33686260 | DOI:10.1038/s41436-020-01090-w
Paternal genetic variants and risk of obstructive heart defects: A parent-of-origin approach
PLoS Genet. 2021 Mar 8;17(3):e1009413. doi: 10.1371/journal.pgen.1009413. eCollection 2021 Mar. ABSTRACT Previous research on risk factors for obstructive heart defects (OHDs) focused on maternal and infant genetic variants, prenatal environmental exposures, and their potential interaction effects. Less is known about the role of paternal genetic variants or environmental exposures and risk of OHDs. We examined […]
