Pegvaliase for the treatment of phenylketonuria: Results of a long-term phase 3 clinical trial program (PRISM)
Mol Genet Metab. 2018 May;124(1):27-38. doi: 10.1016/j.ymgme.2018.03.006. Epub 2018 Mar 31. ABSTRACT BACKGROUND: Phenylketonuria (PKU) is caused by phenylalanine hydroxylase (PAH) deficiency that results in phenylalanine (Phe) accumulation. Pegvaliase, PEGylated recombinant Anabaena variabilis phenylalanine ammonia lyase (PAL), converts Phe to trans-cinnamic acid and ammonia, and is a potential enzyme substitution therapy to lower blood Phe […]
Rapid whole-genome sequencing decreases infant morbidity and cost of hospitalization
NPJ Genom Med. 2018 Apr 4;3:10. doi: 10.1038/s41525-018-0049-4. eCollection 2018. ABSTRACT Genetic disorders are a leading cause of morbidity and mortality in infants. Rapid whole-genome sequencing (rWGS) can diagnose genetic disorders in time to change acute medical or surgical management (clinical utility) and improve outcomes in acutely ill infants. We report a retrospective cohort study […]

The case for early use of rapid whole-genome sequencing in management of critically ill infants: late diagnosis of Coffin-Siris syndrome in an infant with left congenital diaphragmatic hernia, congenital heart disease, and recurrent infections
Cold Spring Harb Mol Case Stud. 2018 Jun 1;4(3):a002469. doi: 10.1101/mcs.a002469. Print 2018 Jun. ABSTRACT Congenital diaphragmatic hernia (CDH) results from incomplete formation of the diaphragm leading to herniation of abdominal organs into the thoracic cavity. CDH is associated with pulmonary hypoplasia, congenital heart disease, and pulmonary hypertension. Genetically, it is associated with aneuploidies, chromosomal […]
Unsupervised Analysis of Transcriptomics in Bacterial Sepsis Across Multiple Datasets Reveals Three Robust Clusters
Crit Care Med. 2018 Jun;46(6):915-925. doi: 10.1097/CCM.0000000000003084. ABSTRACT OBJECTIVES: To find and validate generalizable sepsis subtypes using data-driven clustering. DESIGN: We used advanced informatics techniques to pool data from 14 bacterial sepsis transcriptomic datasets from eight different countries (n = 700). SETTING: Retrospective analysis. SUBJECTS: Persons admitted to the hospital with bacterial sepsis. INTERVENTIONS: None. […]
Acute liver failure in neonates with undiagnosed hereditary fructose intolerance due to exposure from widely available infant formulas
Mol Genet Metab. 2018 Apr;123(4):428-432. doi: 10.1016/j.ymgme.2018.02.016. Epub 2018 Feb 27. ABSTRACT Hereditary fructose intolerance (HFI) is an autosomal recessive disorder caused by aldolase B (ALDOB) deficiency resulting in an inability to metabolize fructose. The toxic accumulation of intermediate fructose-1-phosphate causes multiple metabolic disturbances, including postprandial hypoglycemia, lactic acidosis, electrolyte disturbance, and liver/kidney dysfunction. The […]
A community approach to mortality prediction in sepsis via gene expression analysis
Nat Commun. 2018 Feb 15;9(1):694. doi: 10.1038/s41467-018-03078-2. ABSTRACT Improved risk stratification and prognosis prediction in sepsis is a critical unmet need. Clinical severity scores and available assays such as blood lactate reflect global illness severity with suboptimal performance, and do not specifically reveal the underlying dysregulation of sepsis. Here, we present prognostic models for 30-day […]
The NSIGHT1-randomized controlled trial: rapid whole-genome sequencing for accelerated etiologic diagnosis in critically ill infants
NPJ Genom Med. 2018 Feb 9;3:6. doi: 10.1038/s41525-018-0045-8. eCollection 2018. ABSTRACT Genetic disorders are a leading cause of morbidity and mortality in infants in neonatal and pediatric intensive care units (NICU/PICU). While genomic sequencing is useful for genetic disease diagnosis, results are usually reported too late to guide inpatient management. We performed an investigator-initiated, partially […]
Defining the phenotypic spectrum of SLC6A1 mutations
Epilepsia. 2018 Feb;59(2):389-402. doi: 10.1111/epi.13986. Epub 2018 Jan 8. ABSTRACT OBJECTIVE: Pathogenic SLC6A1 variants were recently described in patients with myoclonic atonic epilepsy (MAE) and intellectual disability (ID). We set out to define the phenotypic spectrum in a larger cohort of SCL6A1-mutated patients. METHODS: We collected 24 SLC6A1 probands and 6 affected family members. Four […]
