Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 0P and 11B. BP4_ModerateBP6BS1BS2

The NM_001376.5(DYNC1H1):​c.13261G>A​(p.Ala4421Thr) variant causes a missense change. The variant allele was found at a frequency of 0.0000173 in 1,614,084 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A4421S) has been classified as Likely benign.

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 was made for transcript

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

BP4
Computational evidence support a benign effect (MetaRNN=0.21834853).
BP6
Variant 14-102048558-G-A is Benign according to our data. Variant chr14-102048558-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 434998.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0000263 (4/152214) while in subpopulation NFE AF = 0.0000588 (4/68042). AF 95% confidence interval is 0.0000197. There are 0 homozygotes in GnomAd4. There are 0 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High AC in GnomAdExome4 at 24 AD gene.
