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]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 14, 2023This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 4144 of the DYNC2H1 protein (p.Pro4144Arg). This variant is present in population databases (rs761765709, gnomAD 0.004%). This missense change has been observed in individual(s) with clinical features of asphyxiating thoracic dystrophy (PMID: 29068549, 30655312, 30773290). 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: 198962). 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. -

Uncertain significance, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpApr 03, 2024Variant summary: DYNC2H1 c.12431C>G (p.Pro4144Arg) results in a non-conservative amino acid change located in the Dynein heavy chain, C-terminal domain (IPR041228) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 248572 control chromosomes (gnomAD). c.12431C>G has been reported in the literature in individuals affected with Short-rib thoracic dysplasia (Zhang_2018, Connaughton_2019, Mann_2019). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 29068549, 30773290, 30655312). ClinVar contains an entry for this variant (Variation ID: 198962). Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic. -
Asphyxiating thoracic dystrophy 3 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 13, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
