DCTN1

Alias

DAP-150; DP-150; P135

Associated disorders

The DCTN1 gene is associated with autosomal dominant Perry syndrome (MedGen UID: 357007), distal hereditary motor neuropathy type VIIB (HMN7B) (MedGen UID: 375157), and amyotrophic lateral sclerosis 1 (ALS1) (MedGen UID: 400169).

The DCTN1 gene is the only known cause of Perry syndrome but is a rare cause of dHMN.

The DCTN1 gene encodes dynactin-1, the largest polypeptide of dynactin complex. This complex plays a critical role in cell division and the transport of materials within cells, and is particularly important for the proper function of axons.

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 in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.

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.
