Genes affected
DCTN6 (HGNC:16964): (dynactin subunit 6) The protein encoded by this gene contains an RGD (Arg-Gly-Asp) motif in the N-terminal region, which confers adhesive properties to macromolecular proteins like fibronectin. It shares a high degree of sequence similarity with the mouse homolog, which has been suggested to play a role in mitochondrial biogenesis. The exact biological function of this gene is not known.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.428T>C (p.I143T) alteration is located in exon 6 (coding exon 6) of the DCTN6 gene. This alteration results from a T to C substitution at nucleotide position 428, causing the isoleucine (I) at amino acid position 143 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
