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.1847_1852del6 variant is predicted to result in an in-frame deletion (p.Ile616_Leu617del). This variant was reported in the compound heterozygous state with another DYNC2H1 missense variant in a patient with perinatal lethal short-rib polydactyly syndrome (Zhang et al 2018. PubMed ID: 29068549). At PreventionGenetics, we have observed this variant with a rare missense variant in a similarly affected family member (internal data). This variant is reported in 0.0019% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-102996010-ATTATTC-A). Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
