Genes affected

DYNC2LI1 (HGNC:24595): (dynein cytoplasmic 2 light intermediate chain 1) This gene encodes a protein that is a component of the dynein-2 microtubule motor protein complex that plays a role in the retrograde transport of cargo in primary cilia via the intraflagellar transport system. This gene is ubiquitously expressed and its protein, which localizes to the axoneme and Golgi apparatus, interacts directly with the cytoplasmic dynein 2 heavy chain 1 protein to form part of the multi-protein dynein-2 complex. Mutations in this gene produce defects in the dynein-2 complex which result in several types of ciliopathy including short-rib thoracic dysplasia 15 with polydactyly (SRTD15). Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Feb 2017]

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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This missense change has been observed in individual(s) with Jeune asphyxiating thoracic dystrophy (PMID: 26874042). This variant is present in population databases (rs576199283, gnomAD 0.0008%). This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 39 of the DYNC2LI1 protein (p.Ser39Cys). -
