Abstract
Inherited ataxias represent one of the most heterogeneous groups of diseases in neurology. Advances in molecular genetics have led to identification of an increasing number of genes responsible for them.
Their correlation of an increasing number of genes resposible for them. Their correlation of phenotype/genotype is in progress, so some of patients are denoted by atypical form.
A further problem is that the majority of studies do not take into account other acquired illnesses and diseases which may fundamentally alter the symptomology and course of a primary disease, not to mention the possibility of concomitancy in hereditary diseases.
