Abstract

Ataxias are a clinically and genetically heterogeneous group of neurological diseases that affects individuals of all age groups causing a degenerative process in the cerebellum and their pathways. The most common genetics forms of ataxias are those caused by trinucleotide repeat expansions that can be easily tested using standard methods. With the advance of diagnostic techniques, many genes could be identified as the cause of previously indeterminate ataxias. However, approximately 40% of patients remains undiagnosed. In this study we aim to establish the molecular diagnosis of a Brazilian population with undetermined ataxia, through the realization of an Exome Whole test and investigate the correlations between genotype and phenotype in this population.
