Genes affected

DCTN3 (HGNC:2713): (dynactin subunit 3) This gene encodes the smallest subunit of dynactin, a macromolecular complex consisting of 10 subunits ranging in size from 22 to 150 kD. Dynactin binds to both microtubules and cytoplasmic dynein. It is involved in a diverse array of cellular functions, including ER-to-Golgi transport, the centripetal movement of lysosomes and endosomes, spindle formation, cytokinesis, chromosome movement, nuclear positioning, and axonogenesis. This subunit, like most other dynactin subunits, exists only as a part of the dynactin complex. It is primarily an alpha-helical protein with very little coiled coil, and binds directly to the largest subunit (p150) of dynactin. Alternative splicing results in multiple transcript variants.

Ambry Genetics

May 11, 2022

The c.16G>A (p.D6N) alteration is located in exon 1 (coding exon 1) of the DCTN3 gene. This alteration results from a G to A substitution at nucleotide position 16, causing the aspartic acid (D) at amino acid position 6 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
