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]

The DYNC2H1 c.6614G>A variant is classified as Likely Pathogenic (PS4_Moderate, PM2, PM3) The DYNC2H1 c.6614G>A variant is a single nucleotide change in exon 41 of 89 of the DYNC2H1 gene, which is predicted to change the amino acid arginine at position 2205 in the protein to histidine. The variant has been reported in at least 2 probands with a clinical presentation of short rib-polydactyly syndrome (PMID:19361615, PMID:29068549) (PS4_Moderate). This variant is absent from population databases (PM2). The phase of this variant with the p.Trp860Ter variant cannot be determined without parental studies. However, this variant was reported to be in trans with a pathogenic variant p.Arg2838Ter for this recessive condition (PMID:19361615) (PM3). Computational predictions provide conflicting interpretations of pathogenicity for this variant (PP3 and BP4 not met). The variant has been reported in dbSNP (rs137853031) and in the HGMD database: CM091950. It has been reported as Pathogenic/Likely pathogenic by other diagnostic laboratories (ClinVar Variation ID: 6507). -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 2205 of the DYNC2H1 protein (p.Arg2205His). This variant is present in population databases (rs137853031, gnomAD 0.003%). This missense change has been observed in individual(s) with short rib polydactyly syndrome (PMID: 19361615, 29068549). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 6507). 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 with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -
