Invitae tests that include this gene:

Because only a small number of ANO3-related dystonia cases have been reported, test sensitivity cannot be predicted. However, findings from one small study suggest that ANO3 may account for approximately 2% of dystonia.

ANO3 encodes anoctamin-3, a transmembrane calcium-activated chloride channel. While little is known about the function of this gene, pathogenic variants of the ANO3 gene lead to defective calcium regulation at the endoplasmic reticulum.

Assay and technical information

Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).

Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence, and select noncoding variants. Our assay provides a Q30 quality-adjusted mean coverage depth of 350x (50x minimum, or supplemented with additional analysis). Variants classified as pathogenic or likely pathogenic are confirmed with orthogonal methods, except individual variants that have high quality scores and previously validated in at least ten unrelated samples.

Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
