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]

The c.20A>G (p.N7S) alteration is located in exon 2 (coding exon 1) of the DNAJC13 gene. This alteration results from a A to G substitution at nucleotide position 20, causing the asparagine (N) at amino acid position 7 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
