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

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.2689621).

BP6

Variant 14-102010755-G-A is Benign according to our data. Variant chr14-102010755-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 408980.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000328 (5/152252) while in subpopulation AFR AF= 0.0000965 (4/41472). AF 95% confidence interval is 0.0000325. There are 0 homozygotes in gnomad4. There are 4 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2

High AC in GnomAd4 at 5 AD gene.

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
