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.

Submissions by phenotype

Charcot-Marie-Tooth disease axonal type 2O Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeNov 06, 2021This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2993 of the DYNC1H1 protein (p.Ile2993Val). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DYNC1H1 protein function. ClinVar contains an entry for this variant (Variation ID: 434989). This variant has not been reported in the literature in individuals affected with DYNC1H1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). -
