The Comprehensive Genetic Test for Ataxia utilizes next-generation sequencing (NGS) to examine 257 genes associated with hereditary ataxia and neurodegenerative disorders. It is a targeted gene panel specifically designed to support accurate diagnosis, risk assessment, and prevention.

More Information

The Comprehensive Genetic Test for Ataxia is a specialized genetic test designed to support the evaluation of individuals with a clinical suspicion of hereditary ataxia. The Comprehensive Genetic Test for Ataxia analyzes a set of related genes, including both coding and selected non-coding regions, and incorporates assessment of the maternally inherited mitochondrial genome. The comprehensive genetic test for ataxia is particularly valuable in cases where repeat expansion disorders have already been excluded based on clinical presentation or prior analysis. The comprehensive genetic test for ataxia is used to investigate the underlying genetic causes of progressive or episodic coordination disorders, enabling a more precise characterization of complex neurological phenotypes associated with cerebellar dysfunction.

The comprehensive genetic test for ataxia includes genes that play essential roles in neuronal development, synaptic transmission, mitochondrial function, and DNA repair. Representative genes such as ATM, FXN, CACNA1A, SETX, and POLG are associated with key cellular pathways including oxidative phosphorylation, ion channel regulation, and genome stability. These biological processes are critical for maintaining cerebellar integrity and coordinated motor control. Disruption of these pathways leads to neuronal degeneration and impaired signal transmission. The comprehensive genetic test for ataxia is indicated in individuals presenting with unexplained ataxia, particularly when common repeat expansion causes have been excluded or are clinically unlikely.

Hereditary ataxias represent a heterogeneous group of neurodegenerative disorders characterized primarily by progressive gait instability and impaired coordination. Clinical manifestations frequently include dysarthria, oculomotor abnormalities, and fine motor difficulties. Episodic forms may present with transient attacks of imbalance, often accompanied by nystagmus, vertigo, or dysarthria, while some subtypes may also include myokymia or sensorineural hearing loss. Both autosomal dominant and autosomal recessive inheritance patterns are observed, with phenotypic variability ranging from early-onset severe presentations to milder adult-onset forms. Cerebellar atrophy is commonly observed and contributes significantly to disease progression.

The purpose of the comprehensive genetic test for ataxia is to identify genetic variants associated with a broad spectrum of hereditary ataxias, including cerebellar ataxias, episodic ataxias, and spinocerebellar ataxias. By encompassing a wide range of relevant genes and the mitochondrial genome, the panel enhances diagnostic yield in genetically complex cases. It facilitates the differentiation between overlapping clinical entities and supports the identification of rare or atypical genetic causes. The results contribute to improved disease classification, enable risk assessment, and provide valuable insights into the molecular basis of neurodegeneration.

A higher genetic risk is confirmed when pathogenic mutations are found in genes associated with hereditary ataxias. A lower risk may be inferred when no mutations are detected, though comprehensive clinical follow-up is still essential. The integration of genetic data with clinical findings and family history is critical for precise diagnosis, prognosis, and long-term patient care.

The test is performed in a clinical laboratory accredited to ISO 15189 and certified by CLIA and CAP, ensuring the validity, accuracy and international recognition of the results.
