Genes affected
DNAJB11 (HGNC:14889): (DnaJ heat shock protein family (Hsp40) member B11) This gene encodes a soluble glycoprotein of the endoplasmic reticulum (ER) lumen that functions as a co-chaperone of binding immunoglobulin protein, a 70 kilodalton heat shock protein chaperone required for the proper folding and assembly of proteins in the ER. The encoded protein contains a highly conserved J domain of about 70 amino acids with a characteristic His-Pro-Asp (HPD) motif and may regulate the activity of binding immunoglobulin protein by stimulating ATPase activity.

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 14 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. There are 4 pathogenic variants in the truncated region.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 3-186572096-C-T is Pathogenic according to our data. Variant chr3-186572096-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 1172653.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Submissions by phenotype

Polycystic kidney disease Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineAug 30, 2022The p.Arg24X in DNAJB11 has been reported in the 3 individual with autosomal dominant polycystic kidney disease (ADPKD) (Huynh 2022 PMID: 32631624), and is absent in large population databases. This nonsense variant leads to a premature termination codon at position 24, which is predicted to lead to a truncated or absent protein. Loss of function of the DNAJB11 gene is an established disease mechanism in autosomal dominant ADPKD. In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant polycystic kidney disease. ACMG/AMP criteria applied: PVS1, PS4_Moderate, PM2_Supporting. -
