Genes affected

DYNC1LI1 (HGNC:18745): (dynein cytoplasmic 1 light intermediate chain 1) The protein encoded by this gene belongs to light intermediate subunit family, whose members are components of the multiprotein cytoplasmic dynein complex, which is involved in intracellular trafficking and chromosome segregation during mitosis. The protein plays a role in moving the spindle assembly checkpoint (SAC) from kinetochores to spindle poles. The protein may also mediate binding to other cargo molecules to facilitate intracellular vesicle trafficking. [provided by RefSeq, Jul 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.36476496).

The c.1105G>A (p.A369T) alteration is located in exon 9 (coding exon 9) of the DYNC1LI1 gene. This alteration results from a G to A substitution at nucleotide position 1105, causing the alanine (A) at amino acid position 369 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
