Genes affected

DNAJC13 (HGNC:30343): (DnaJ heat shock protein family (Hsp40) member C13) This gene encodes a member of the Dnaj protein family whose members act as co-chaperones of a partner heat-shock protein by binding to the latter and stimulating ATP hydrolysis. The encoded protein associates with the heat-shock protein Hsc70 and plays a role in clathrin-mediated endocytosis. It may also be involved in post-endocytic transport mechanisms via its associations with other proteins, including the sorting nexin SNX1. Mutations in this gene are associated with Parkinson's disease. [provided by RefSeq, Jun 2016]

Collection Method: clinical testing

The DNAJC13 c.197C>T variant is predicted to result in the amino acid substitution p.Thr66Met. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.010% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/3-132166217-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
