Genes affected

DYNC2H1 (HGNC:2962): (dynein cytoplasmic 2 heavy chain 1) This gene encodes a large cytoplasmic dynein protein that is involved in retrograde transport in the cilium and has a role in intraflagellar transport, a process required for ciliary/flagellar assembly. Mutations in this gene cause a heterogeneous spectrum of conditions related to altered primary cilium function and often involve polydactyly, abnormal skeletogenesis, and polycystic kidneys. Alternative splicing results in multiple transcript variants encoding distinct proteins. [provided by RefSeq, Jan 2010]

This variant has not been reported in the literature in individuals affected with DYNC2H1-related conditions. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.Arg3374 amino acid residue in DYNC2H1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 26938784, 28832562, 29453417; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 expected to disrupt DYNC2H1 protein function. This variant is present in population databases (rs200710887, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with serine, which is neutral and polar, at codon 3374 of the DYNC2H1 protein (p.Arg3374Ser). -
