Associated disorders

Pathogenic variants in the DEPDC5 gene are associated with ~10% of clinical cases of familial focal epilepsy with variable foci (FFEVF).

Nutrient-sensing is central to essential cellular functions like growth, division, and survival. The DEPDC5 gene encodes a subunit of the GATOR1 complex, which inhibits nutrient-sensing pathways and may result in unrestrained or unorganized cell growth when not properly regulated (PMID: 23723238, 25833943).

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.
