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]

Review Status:criteria provided, single submitter

In summary, this is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this sequence change is likely to be disruptive, but these predictions have not been confirmed by published functional studies. This sequence change has not been published in the literature and is not present in population databases. This sequence change replaces proline with alanine at codon 3420 of the DYNC2H1 protein (p.Pro3420Ala). The proline residue is highly conserved and there is a small physicochemical difference between proline and alanine. -
