ATXN10
Encyclopedia
Ataxin-10 is a protein
that in humans is encoded by the ATXN10 gene
.
s (ADCAs) are a clinically and genetically heterogeneous group of disorders characterized by ataxia, dysarthria, dysmetria, and intention tremor. All ADCAs involve some degree of cerebellar dysfunction and a varying degree of signs from other components of the nervous system. A commonly accepted clinical classification (Harding, 1993) divides ADCAs into 3 different groups based on the presence or absence of associated symptoms such as brainstem signs or retinopathy. The presence of pyramidal and extrapyramidal symptoms and ophthalmoplegia makes the diagnosis of ADCA I, the presence of retinopathy points to ADCA II, and the absence of associated signs to ADCA III. Genetic linkage and molecular analyses revealed that ADCAs are genetically heterogeneous even within the various subtypes.
Defects in ATXN10 have been associated with Joubert syndrome

Protein
Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

Gene
A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...
