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 -19 ACMG points.

• BP4: Computational evidence support a benign effect (REVEL=0.182).
• BP6: Variant 14-102036543-A-G is Benign according to our data. Variant chr14-102036543-A-G is described in ClinVar as Likely_benign. ClinVar VariationId is 434976.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=2.72 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.00000616 (9/1461852) while in subpopulation SAS AF = 0.000104 (9/86258). AF 95% confidence interval is 0.0000539. There are 0 homozygotes in GnomAdExome4. There are 3 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.
• BS2: High AC in GnomAdExome4 at 9 AD gene.
