Published: January 2005

Ataxia is a common and important neurological finding in medical practice. Severe deficiency of Vitamin E can profoundly affect the central nervous system and can cause ataxia and peripheral neuropathy resembling Friedreich's ataxia. Vitamin E deficiency can occur with abetalipoproteinemia, cholestatic liver disease or fat malabsorption. Ataxia with isolated Vit E deficiency (AVED) is an Autosomal Recessive genetic disorder with a mutation in the alpha tocopherol transfer protein gene (TTPA). This condition responds to high dose of Vit E and is one of the important causes of treatable ataxia. We report a young patient with Ataxia with isolated Vit E deficiency (AVED) who responded partially to replacement of Vitamin E.

Cerebellar Purkinje cells (PCs) exhibit a unique interplay of high metabolic rates, specific chromatin architecture, and extensive transcriptional activity, making them particularly vulnerable to DNA damage. This necessitates an efficient DNA damage response (DDR) to prevent cerebellar degeneration, often initiated by PC dysfunction or loss. A notable example is the genome instability syndrome, ataxia-telangiectasia (A-T), marked by progressive PC depletion and cerebellar deterioration.

Identification of genetic mechanisms of non-isolated auditory neuropathy with various phenotypes in Chinese families.

Background: Non-isolated auditory neuropathy (AN), or syndromic AN, is marked by AN along with additional systemic manifestations. The diagnostic process is challenging due to its varied symptoms and overlap with other syndromes. This study focuses on two mitochondrial function-related genes which result in non-isolated AN, FDXR and TWNK, providing a summary and enrichment analysis of genes associated with non-isolated AN to elucidate the genotype-phenotype correlation and underlying mechanisms.

The cerebellum, a key target of ethanol's toxic effects, is associated with ataxia following alcohol consumption. However, the impact of ethanol on Purkinje cell (PC) mitochondria remains unclear. To investigate how ethanol administration affects mitochondrial dynamics in cerebellar Purkinje cells, we employed a transgenic mouse model expressing mitochondria-targeted yellow fluorescent protein in Purkinje cells (PC-mito-eYFP).

Background/objective: 4H syndrome is a rare form of leukodystrophy characterized by hypomyelination, hypodontia, and hypogonadotropic hypogonadism. In 95% of cases, hypomyelination is present, but other clinical features, such as hypodontia and hypogonadotropic hypogonadism, are not always present and may not be necessary for diagnosis. Hypogonadotropic hypogonadism is the most common endocrine complication that can occur in 4H syndrome.

Introduction: The late autumn epizootic of the highly pathogenic avian influenza virus (HPAIV) subtype H5N1 in Serbia in 2023 caused massive mortality in the migratory population of common cranes (). This is the first time HPAIV has been identified in the common crane in Serbia, leading to mass mortality of this bird species.

Methods: To understand the pathological impact of HPAIV in cranes, we evaluated the pathological changes in the tissues of common cranes.
