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]

This sequence change creates a premature translational stop signal (p.Trp124*) in the DYNC2LI1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DYNC2LI1 are known to be pathogenic (PMID: 26077881, 26130459). This variant is present in population databases (rs769975073, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with short-rib thoracic dysplasia (PMID: 26077881). ClinVar contains an entry for this variant (Variation ID: 212766). For these reasons, this variant has been classified as Pathogenic. -
