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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 446595). This premature translational stop signal has been observed in individual(s) with short-rib thoracic dysplasia (PMID: 29068549). This variant is present in population databases (rs759649136, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Leu3647Serfs*38) 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). -
