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]

This sequence change creates a premature translational stop signal (p.Asn2845Ilefs*8) 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). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with short rib polydactyly syndrome (PMID: 22499340). ClinVar contains an entry for this variant (Variation ID: 40071). For these reasons, this variant has been classified as Pathogenic. -
