Genes affected
DYNC1H1 (HGNC:2961): (dynein cytoplasmic 1 heavy chain 1) Dyneins are a group of microtubule-activated ATPases that function as molecular motors. They are divided into two subgroups of axonemal and cytoplasmic dyneins. The cytoplasmic dyneins function in intracellular motility, including retrograde axonal transport, protein sorting, organelle movement, and spindle dynamics. Molecules of conventional cytoplasmic dynein are comprised of 2 heavy chain polypeptides and a number of intermediate and light chains.This gene encodes a member of the cytoplasmic dynein heavy chain family.

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.K3491N variant (also known as c.10473A>C), located in coding exon 55 of the DYNC1H1 gene, results from an A to C substitution at nucleotide position 10473. The lysine at codon 3491 is replaced by asparagine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

The DYNC1H1 c.10473A>C variant is predicted to result in the amino acid substitution p.Lys3491Asn. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0029% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/14-102500372-A-C). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
