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.

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DYNC1H1. . Gene score misZ 10.967 (greater than the threshold 3.09). Trascript score misZ 16.053 (greater than threshold 3.09). GenCC has associacion of gene with 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, 0.752
