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.1657_1660delTTGT variant is predicted to result in a frameshift and premature protein termination (p.Leu553Valfs*18). This variant has been reported in an individual with short rib-polydactyly syndrome (Table S2, Zhang et al. 2018. PubMed ID: 29068549). This variant is reported in 0.0021% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Frameshift variants in DYNC2H1 are expected to be pathogenic. This variant is interpreted as pathogenic. -

This sequence change creates a premature translational stop signal (p.Leu553Valfs*18) 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 (rs748906528, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with DYNC2H1-related conditions (PMID: 29068549). ClinVar contains an entry for this variant (Variation ID: 446569). For these reasons, this variant has been classified as Pathogenic. -
