Genes affected
DOLK (HGNC:23406): (dolichol kinase) The protein encoded by this gene catalyzes the CTP-mediated phosphorylation of dolichol, and is involved in the synthesis of Dol-P-Man, which is an essential glycosyl carrier lipid for C- and O-mannosylation, N- and O-linked glycosylation of proteins, and for the biosynthesis of glycosyl phosphatidylinositol anchors in endoplasmic reticulum. Mutations in this gene are associated with dolichol kinase deficiency.[provided by RefSeq, Apr 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.6).
BP6
Variant 9-128946533-G-A is Benign according to our data. Variant chr9-128946533-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 390952.
BP7
Synonymous conserved (PhyloP=1.99 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00185 (282/152282) while in subpopulation AFR AF = 0.00652 (271/41556). AF 95% confidence interval is 0.00588. There are 0 homozygotes in GnomAd4. There are 136 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 2 AR,AD gene
