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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.023004979).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000461 (65/1411042) while in subpopulation AMR AF= 0.00137 (55/40168). AF 95% confidence interval is 0.00108. There are 0 homozygotes in gnomad4_exome. There are 26 alleles in male gnomad4_exome subpopulation. Median coverage is 26. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces threonine, which is neutral and polar, with serine, which is neutral and polar, at codon 5 of the DYNC2LI1 protein (p.Thr5Ser). This variant is present in population databases (rs750299666, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with DYNC2LI1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1446256). 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 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. -
