Abstrakt: Spinocerebellar ataxia autosomal recessive (SCAR) represents a heterogeneous chronic and progressive neurological diseases group. They usually occur at an early age in a progressive manner. Diagnosis is complex due to phenotypic overlap. SCARs account for more than 50% of all ataxia cases of genetic origin, with a prevalence of 3–4/100 000. According to international published series, Friedreich's ataxia (FA) is the most common. In Mexico, more than 90% of patients with suspected SCAR remain without etiologic diagnosis after ruling out FA and acquired causes of ataxia. Our main goal was to reach a diagnosis using genomic tools in this group of patients.
