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 c.6918A>G; p.Ser2306Ser variant (rs368824340, ClinVar variant ID 281774) does not alter the amino acid sequence of the DYNC2H1 protein and computational splice site prediction algorithms do not predict a change in the nearest splice site or creation of a cryptic splice site. This variant has not been reported in association with skeletal dysplasia in medical literature or in gene specific variation databases. This variant is listed in the genome Aggregation Database (gnomAD) with an African population frequency of 0.3% (identified on 75 out of 23,996 chromosomes). Based on the available information, the c.6918A>G variant is likely to be benign.
