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]

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the DYNC2LI1 protein in which other variant(s) (p.Leu117Val) have been determined to be pathogenic (PMID: 26077881, 32815859). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 518437). Disruption of the initiator codon has been observed in individual(s) with Ellis-van Creveld syndrome (PMID: 28857138). This variant is present in population databases (rs200859699, gnomAD 0.01%). This sequence change affects the initiator methionine of the DYNC2LI1 mRNA. The next in-frame methionine is located at codon 127. -
