Genes affected

DNAJC12 (HGNC:28908): (DnaJ heat shock protein family (Hsp40) member C12) This gene encodes a member of a subclass of the HSP40/DnaJ protein family. Members of this family of proteins are associated with complex assembly, protein folding, and export. Two transcript variants encoding distinct isoforms have been identified for this gene.

Invitae

Jul 21, 2023

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the DNAJC12 protein in which other variant(s) (p.Trp175*) have been determined to be pathogenic (PMID: 30626930, 32333439). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with DNAJC12-related conditions. This variant is present in population databases (rs753374676, gnomAD 0.006%). This sequence change creates a premature translational stop signal (p.Gln162*) in the DNAJC12 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 37 amino acid(s) of the DNAJC12 protein. -
