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.

This sequence change creates a premature translational stop signal (p.Arg34*) in the DNAJB11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAJB11 are known to be pathogenic (PMID: 32631624). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This premature translational stop signal has been observed in individual(s) with polycystic kidney disease (PMID: 32631624). For these reasons, this variant has been classified as Pathogenic. -
