The neuropsychiatry of inborn errors of metabolism [PDF]

open access: yesJournal of Inherited Metabolic Disease, 2013
AbstractA number of metabolic disorders that affect the central nervous system can present in childhood, adolescence or adulthood as a phenocopy of a major psychiatric syndrome such as psychosis, depression, anxiety or mania. An understanding and awareness of secondary syndromes in metabolic disorders is of great importance as it can lead to the early ...

The incidence of portal vein thrombosis at liver transplantation [PDF]

open access: yes, 1992
The incidence of portal vein thrombosis was examined in 885 patients who received orthotopic liver transplantations for various end‐stage liver diseases between 1989 and 1990. The thrombosis was classified into four grades.

Identification and Characterization of a Novel Biallelic SLC12A2 Variant Associated With Kilquist Syndrome (OMIM #619080)

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This study presents the case of a child with multiple congenital anomalies, severe hypotonia, and profound bilateral sensorineural hearing loss. Functional bioenergetic assessments showed no significant mitochondrial respiratory defects, and riboflavin (Rf) status evaluation excluded a deficiency in Rf transporters as a cause of hearing loss ...

Molecular characterization of phenylketonuria patients from the North Region of Brazil: State of Pará

open access: yesMolecular Genetics & Genomic Medicine, 2023
Background Phenylketonuria (PKU) is an autosomal recessive disease resulting from a deficiency of the enzyme phenylalanine hydroxylase (PAH). Hyperphenylalaninemias (HPA) due to PAH deficiency are accompanied by a wide variety of clinical, biochemical ...

Analysis of Catecholamines and Pterins in Inborn Errors of Monoamine Neurotransmitter Metabolism—From Past to Future

open access: yesCells, 2019
Inborn errors of monoamine neurotransmitter biosynthesis and degradation belong to the rare inborn errors of metabolism. They are caused by monogenic variants in the genes encoding the proteins involved in (1) neurotransmitter biosynthesis (like tyrosine

Orotic Aciduria [PDF]

open access: yes, 2018
Orotic acid is an intermediate found in the pathway for pyrimidine synthesis. The mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) catalyzes the production of orotic acid by the conversion of the compound dihydroorotate to orotic acid.

Restoring Ureagenesis in Hepatocytes by CRISPR/Cas9-mediated Genomic Addition to Arginase-deficient Induced Pluripotent Stem Cells. [PDF]

open access: yes, 2016
Urea cycle disorders are incurable enzymopathies that affect nitrogen metabolism and typically lead to hyperammonemia. Arginase deficiency results from a mutation in Arg1, the enzyme regulating the final step of ureagenesis and typically results in ...

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 ...

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 ...

Expanded Newborn Screening for Inborn Errors of Metabolism and Genetic Characteristics in a Chinese Population

open access: yesFrontiers in Genetics, 2018
The incidence of inborn errors of metabolisms (IEMs) varies dramatically in different countries and regions. Expanded newborn screening for IEMs by tandem mass spectrometry (MS/MS) is an efficient approach for early diagnosis and presymptomatic treatment
