Abstract

Molecular diagnosis is difficult to achieve in disease groups with a highly heterogeneous genetic background, such as cerebellar ataxia. In many patients it is not possible to reach a genetic conclusion. In the past few years, the introduction in everyday genetic diagnostic process of innovative approaches, such as Next Generation Sequencing (NGS), has revolutioned the paradigm of clinical diagnostics defining the disease mutation in affected patients and putting end to their “diagnostic odyssey". Here, we use NGS strategies (Target Resequencing Panel, Exome Sequencing, Whole Genome Sequencing) to define the molecular characterization of a cohort of 120 patients with undiagnosed ataxia. To date, we found confirmed pathogenic variants in 55 analyzed patients. Mutations were identified in a broad range of genes implicated in ataxia and related neurologic diseases.
