Unbalance between Excitation and Inhibition in Phenylketonuria, a Genetic Metabolic Disease Associated with Autism [PDF]

open access: yes, 2017
Phenylketonuria (PKU) is the most common genetic metabolic disease with a well-documented association with autism spectrum disorders. It is characterized by the deficiency of the phenylalanine hydroxylase activity, causing plasmatic hyperphenylalaninemia

Case Series of Nizon‐Isidor Syndrome by Heterozygous Variants in MED12L With Further Evidence of Mitotic Instability in One Case With Diploid–Triploid Mosaicism

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nizon‐Isidor syndrome is a rare disorder caused by heterozygous variants in MED12L, with only eight documented cases in the literature. Here, we present three additional cases of this syndrome. Proband 1 was a 7‐year‐old female who presented with developmental delay, right‐leg hemihypertrophy, laryngeal cleft, esotropia, abnormal skin ...

Diagnosis of inborn errors of metabolism within the expanded newborn screening in the Madrid region

open access: yesJIMD Reports, 2022
We present the results of our experience in the diagnosis of inborn errors of metabolism (IEM) since the Expanded Newborn Screening was implemented in our Region. Dried blood samples were collected 48 h after birth.

Sequential magnetic resonance spectroscopic changes in a patient with nonketotic hyperglycinemia [PDF]

open access: yes, 2012
Nonketotic hyperglycinemia (NKH) is a rare inborn error of amino acid metabolism. A defect in the glycine cleavage enzyme system results in highly elevated concentrations of glycine in the plasma, urine, cerebrospinal fluid, and brain, resulting in ...

An OGT Missense Variant With Impaired Enzyme Activity in a Child With Severe Developmental Delay and Hepatoblastoma

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT O‐GlcNAc transferase (OGT) and its antagonist O‐GlcNAcase (OGA) regulate protein O‐GlcNAcylation, a highly conserved post‐translational modification involved in metabolic sensing. Pathogenic variants in the OGT gene cause an X‐linked congenital disorder of glycosylation (OGT‐CDG) presenting developmental delay, hypotonia, intellectual ...

Dysmorphology of inborn errors of metabolism [PDF]

open access: yesMolecular Cytogenetics, 2014
As we discover the molecular mechanism of disorders, eventually all dysmorphic syndromes will ultimately be considered biochemical defects. An overview on the recognition and classification of dysmorphic features will be provided. Categories of inborn errors of metabolism associated with dysmorphic manifestations will be discussed. For e.g.

Neurodevelopmental Phenotyping and Genotyping in the Pediatric National Institute of Health Undiagnosed Disease Program

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT The National Institute of Health (NIH) Undiagnosed Diseases Program (UDP) is an NIH project with the goal of providing both a comprehensive diagnosis and a better understanding of the many mechanisms of disease for patients with rare and undiagnosed conditions.

Cerebrospinal Fluid Metabolome in Central Nervous System Infections: A Study of Diagnostic Accuracy

open access: yesAnnals of Neurology, EarlyView.
Objective To assess the diagnostic accuracy of metabolites in cerebrospinal fluid (CSF) for central nervous system (CNS) infections. Methods Patients were derived from three prospective cohort studies in the Netherlands. All studies included adults suspected of a CNS infection who underwent a diagnostic lumbar puncture.

Not So Rare: Errors of Metabolism during the Neonatal Period

open access: yes, 2003
During the neonatal period, the diagnosis of an error of metabolism (EM) was once thought to portend a poor prognosis or lethality. Over the past two decades, the prognosis of many EMs has changed.
