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 replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 2160 of the DYNC2H1 protein (p.Asn2160Lys). This variant is present in population databases (rs775426647, gnomAD 0.008%). This missense change has been observed in individual(s) with DYNC2H1-related conditions (PMID: 29068549). ClinVar contains an entry for this variant (Variation ID: 446572). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
