This NGS panel performs the complete sequencing (exons and flanking intronic regions) and copy number variation (CNV) analyses using next generation sequencing (NGS) of genes related to recessive and dominant forms of ataxia. This panel includes the investigation for Ataxia-Teleangiectasia, Ataxia with Oculomotor Apraxia, among others. It’s important to emphasize that this test sequences the gene codifying regions of the panel and does not test the presence of expansion which are the main cause of many autosomal dominant inheritance ataxias with onset in the adult age (SCA1, SCA2, SCA3, SCA6, SCA7, SCA10, SCA12, DRPLA, or others). For this reason, for cases of dominant ataxias of onset in the adult age, the test must be preceded by the Expansion Ataxia Panel. It also does not evaluate the expansion in FXN gene generally associated with Friedreich ataxia.
