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

Our verdict: Benign. The variant received -11 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.23088214).
• BP6: Variant 14-101964783-A-G is Benign according to our data. Variant chr14-101964783-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 581712.
• BS1: Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000069 (10/1449852) while in subpopulation AMR AF = 0.0000684 (3/43840). AF 95% confidence interval is 0.0000181. There are 0 homozygotes in GnomAdExome4. There are 7 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAdExome4 at 10 AD gene.
