A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

A missense mutation in PDHB gene: identification of the patient with pyruvate dehydrogenase deficiency and demonstration of pathogenicity in vitro

Italian Journal of Pediatrics
Background Pyruvate dehydrogenase (PDH) deficiency is an uncommon condition responsible for primary refractory lactic acidosis, and PDH E1β (PDHB) subunit gene mutation rarely causes of PDH deficiency.

[Point mutation].

Nihon rinsho. Japanese journal of clinical medicine, 2019
A point mutation is when a single base pair is altered. Point mutations can have one of three effects. First, the base substitution can be a silent mutation where the altered codon corresponds to the same amino acid.

SPG4 and Dementia: Expanding the Clinical Spectrum

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.

The molecular genetic analysis of the expanding pachyonychia congenita case collection [PDF]

, 2014
BACKGROUND: Pachyonychia congenita (PC) is a rare autosomal dominant keratinizing disorder characterized by severe, painful, palmoplantar keratoderma and nail dystrophy, often accompanied by oral leucokeratosis, cysts and follicular keratosis.

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

Preliminary study on the function of the POLD1 (CDC2) EXON2 c.56G>A mutation

Molecular Genetics & Genomic Medicine, 2020
Background Fanconi anemia (FA) is a rare recessive disease characterized by DNA damage repair deficiency, and DNA polymerase δ (whose catalytic subunit is encoded by POLD1, also known as CDC2) is closely related to DNA damage repair.

Familial hypomagnesaemia, Hypercalciuria and Nephrocalcinosis associated with a novel mutation of the highly conserved leucine residue 116 of Claudin 16 in a Chinese patient with a delayed diagnosis: A case report [PDF]

, 2018
Background: Sixty mutations of claudin 16 coding gene have been reported in familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) patients. Recent investigations revealed that a highly conserved glycine-leucine-tryptophan (115G-L-W117)

Neurodevelopmental disease genes implicated by de novo mutation and copy number variation morbidity

Nature Genetics, 2018
We combined de novo mutation (DNM) data from 10,927 individuals with developmental delay and autism to identify 253 candidate neurodevelopmental disease genes with an excess of missense and/or likely gene-disruptive (LGD) mutations.

Mutator phenotypes of common polymorphisms and missense mutations in MSH2 [PDF]

Current Biology, 1999
Hereditary non-polyposis colorectal cancer (HNPCC) is associated with germline mutations in the DNA mismatch repair gene hMSH2 [1], the human homologue of the Escherichia coli MutS gene. These are mostly nonsense, frameshift or deletion mutations that result in loss of intact protein and complete inactivation of DNA mismatch repair.
