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 Benign. Variant got -16 ACMG points.

• BP6: Variant 14-101988691-CGTT-C is Benign according to our data. Variant chr14-101988691-CGTT-C is described in ClinVar as [Likely_benign]. Clinvar id is 415324.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000184 (28/152160) while in subpopulation NFE AF= 0.000191 (13/68044). AF 95% confidence interval is 0.000112. There are 0 homozygotes in gnomad4. There are 11 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAd at 28 AD gene.
