Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_001376.5(DYNC1H1):c.9138G>T(p.Ser3046Ser) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000446 in 1,614,140 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. S3046S) 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 -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.7).

BP6

Variant 14-102027708-G-T is Benign according to our data. Variant chr14-102027708-G-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 210887.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00252 (383/152256) while in subpopulation AFR AF = 0.00864 (359/41550). AF 95% confidence interval is 0.0079. There are 3 homozygotes in GnomAd4. There are 167 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 383 AD gene.
