A Human Pleiotropic Multiorgan Condition Caused by Deficient Wnt Secretion
N Engl J Med. 2021 Sep 30;385(14):1292-1301. doi: 10.1056/NEJMoa2033911. ABSTRACT BACKGROUND: Structural birth defects occur in approximately 3% of live births; most such defects lack defined genetic or environmental causes. Despite advances in surgical approaches, pharmacologic prevention remains largely out of reach. METHODS: We queried worldwide databases of 20,248 families that included children with neurodevelopmental […]
Effect of Whole-Genome Sequencing on the Clinical Management of Acutely Ill Infants With Suspected Genetic Disease: A Randomized Clinical Trial
JAMA Pediatr. 2021 Sep 27. doi: 10.1001/jamapediatrics.2021.3496. Online ahead of print. ABSTRACT IMPORTANCE: Whole-genome sequencing (WGS) shows promise as a first-line genetic test for acutely ill infants, but widespread adoption and implementation requires evidence of an effect on clinical management. OBJECTIVE: To determine the effect of WGS on clinical management in a racially and ethnically […]
Insights into the expanding phenotypic spectrum of inherited disorders of biogenic amines
Nat Commun. 2021 Sep 20;12(1):5529. doi: 10.1038/s41467-021-25515-5. ABSTRACT Inherited disorders of neurotransmitter metabolism are rare neurodevelopmental diseases presenting with movement disorders and global developmental delay. This study presents the results of the first standardized deep phenotyping approach and describes the clinical and biochemical presentation at disease onset as well as diagnostic approaches of 275 patients […]

Maternal Smoking and Congenital Heart Defects, National Birth Defects Prevention Study, 1997-2011
J Pediatr. 2021 Sep 8:S0022-3476(21)00877-5. doi: 10.1016/j.jpeds.2021.09.005. Online ahead of print. ABSTRACT OBJECTIVES: To assess associations between maternal smoking and congenital heart defects (CHDs) in offspring. STUDY DESIGN: We performed a retrospective case-control study using data for cases of CHD (n=8,339) and non-malformed controls (n=11,020) children from all years (1997-2011) of the National Birth Defects […]
Perspectives of Pediatric Providers Regarding Clinical Use of Pharmacogenetics
S D Med. 2021 Jul;74(7):294-301. ABSTRACT INTRODUCTION: A major goal of the current personalized medicine era is to utilize pharmacogenetics (PGx) in order to influence how medications and therapies are prescribed by providers. However, disparities for prescribing medications between adults and children exist. Research has shown that children are not just small adults and there […]
Integrative genetic, genomic and transcriptomic analysis of heat shock protein and nuclear hormone receptor gene associations with spontaneous preterm birth
Sci Rep. 2021 Aug 24;11(1):17115. doi: 10.1038/s41598-021-96374-9. ABSTRACT Heat shock proteins are involved in the response to stress including activation of the immune response. Elevated circulating heat shock proteins are associated with spontaneous preterm birth (SPTB). Intracellular heat shock proteins act as multifunctional molecular chaperones that regulate activity of nuclear hormone receptors. Since SPTB has […]
Detecting methylation quantitative trait loci using a methylation random field method
Brief Bioinform. 2021 Aug 19:bbab323. doi: 10.1093/bib/bbab323. Online ahead of print. ABSTRACT DNA methylation may be regulated by genetic variants within a genomic region, referred to as methylation quantitative trait loci (mQTLs). The changes of methylation levels can further lead to alterations of gene expression, and influence the risk of various complex human diseases. Detecting […]
To Be or No B2: A Rare Cause of Stridor and Weakness in a Toddler
Child Neurol Open. 2021 Aug 5;8:2329048X211030723. doi: 10.1177/2329048X211030723. eCollection 2021 Jan-Dec. ABSTRACT We present a case of a young child with a rare metabolic disorder whose clinical presentation resembled that of autoimmune myasthenia gravis. The differential diagnosis was expanded when autoantibody testing was negative and the patient did not respond to standard immunomodulatory therapies. Rapid […]
Rapid whole genome sequencing in critically ill children: Shifting from unease to evidence, education and equitable implementation
J Pediatr. 2021 Aug 11:S0022-3476(21)00761-7. doi: 10.1016/j.jpeds.2021.08.006. Online ahead of print. NO ABSTRACT PMID:34390697 | DOI:10.1016/j.jpeds.2021.08.006
