Genes affected

DCTN5 (HGNC:24594): (dynactin subunit 5) This gene encodes a subunit of dynactin, a component of the cytoplasmic dynein motor machinery involved in minus-end-directed transport. The encoded protein is a component of the pointed-end subcomplex and is thought to bind membranous cargo. A pseudogene of this gene is located on the long arm of chromosome 1. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

The c.378C>G (p.C126W) alteration is located in exon 5 (coding exon 5) of the DCTN5 gene. This alteration results from a C to G substitution at nucleotide position 378, causing the cysteine (C) at amino acid position 126 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
