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]

Collection Method:clinical testing

The DYNC2H1 c.10594C>T; p.Arg3532Ter variant (rs181011657) is reported in the literature in the compound heterozygous state, in individuals with short-rib polydactyly (Badiner 2017, Vora 2017), and bilateral hand and foot polydactyly (Meng 2017). This variant is in ClinVar (Variation ID: 446570) and is listed in the genome Aggregation Database with an overall population frequency of 0.006% (identified on 17 out of 264,854 chromosomes). The c.10594C>T variant creates a termination in the DYNC2H1 protein at codon 3532 in exon 70 which is predicted to result in a truncated or absent protein product. Based on these observations, the p.Arg3532Ter has been classified as pathogenic. Pathogenic variants in DYNC2H1 follow autosomal recessive and digenic recessive (with NEK1 variants) inheritance patterns and are associated with short-rib thoracic dysplasia (SRTD) 3 with or without polydactyly (MIM: 613091).

Variant summary: DYNC2H1 c.10594C>T (p.Arg3532X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 6.8e-05 in 236494 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in DYNC2H1 causing Short-rib thoracic dysplasia (6.8e-05 vs 0.0025), allowing no conclusion about variant significance. c.10594C>T has been reported in the literature in individuals affected with Short-rib thoracic dysplasia (e.g. Badiner_2017). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication have been ascertained in the context of this evaluation (PMID: 27925158). ClinVar contains an entry for this variant (Variation ID: 446570). Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change creates a premature translational stop signal (p.Arg3532*) in the DYNC2H1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DYNC2H1 are known to be pathogenic (PMID: 23339108, 32753734, 33755199). This variant is present in population databases (rs181011657, gnomAD 0.05%). This premature translational stop signal has been observed in individual(s) with short-rib polydactyly type I, Saldino-Noonan type (PMID: 27925158). ClinVar contains an entry for this variant (Variation ID: 446570). For these reasons, this variant has been classified as Pathogenic. -
