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.

DYNC1H1 NM_001376.4 exon 66 p.Thr4064= (c.1219G>A): This variant has not been reported in the literature but is present in 3/126710 European alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs114906811). This variant is present in ClinVar (Variation ID:379520). Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. Of note, this variant is a silent variant and does not change the amino acid, reducing the probability that this variant is disease causing. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
