Genes affected

DNAJA3 (HGNC:11808): (DnaJ heat shock protein family (Hsp40) member A3) This gene encodes a member of the DNAJ/Hsp40 protein family. DNAJ/Hsp40 proteins stimulate the ATPase activity of Hsp70 chaperones and play critical roles in protein folding, degradation, and multimeric complex assembly. The encoded protein is localized to mitochondria and mediates several cellular processes including proliferation, survival and apoptotic signal transduction. The encoded protein also plays a critical role in tumor suppression through interactions with oncogenic proteins including ErbB2 and the p53 tumor suppressor protein. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Aug 2011]

Ambry Genetics

Sep 13, 2023

The c.22C>G (p.R8G) alteration is located in exon 1 (coding exon 1) of the DNAJA3 gene. This alteration results from a C to G substitution at nucleotide position 22, causing the arginine (R) at amino acid position 8 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
