Genes affected

DYNC1H1 (HGNC:2961): (dynein cytoplasmic 1 heavy chain 1) Dyneins are a group of microtubule-activated ATPases that function as molecular motors. They are divided into two subgroups of axonemal and cytoplasmic dyneins. The cytoplasmic dyneins function in intracellular motility, including retrograde axonal transport, protein sorting, organelle movement, and spindle dynamics. Molecules of conventional cytoplasmic dynein are comprised of 2 heavy chain polypeptides and a number of intermediate and light chains.This gene encodes a member of the cytoplasmic dynein heavy chain family.

ENSG00000258959 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the DYNC1H1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 122 curated pathogenic missense variants (we use a threshold of 10). The gene has 287 curated benign missense variants. Gene score misZ: 10.967 (above the threshold of 3.09). Trascript score misZ: 16.053 (above the threshold of 3.09). GenCC associations: The gene is linked to autosomal dominant non-syndromic intellectual disability, neuronopathy, distal hereditary motor, intellectual disability, autosomal dominant 13, autosomal dominant childhood-onset proximal spinal muscular atrophy without contractures, Charcot-Marie-Tooth disease axonal type 2O.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.847
