Genes affected

DNAJB8 (HGNC:23699): (DnaJ heat shock protein family (Hsp40) member B8) The protein encoded by this gene belongs to the DNAJ/HSP40 family of proteins that regulate chaperone activity. This family member suppresses aggregation and toxicity of polyglutamine proteins, and the C-terminal tail is essential for this activity. It has been implicated as a cancer-testis antigen and as a cancer stem-like cell antigen involved in renal cell carcinoma. [provided by RefSeq, Jun 2012]

The c.172G>A (p.D58N) alteration is located in exon 3 (coding exon 1) of the DNAJB8 gene. This alteration results from a G to A substitution at nucleotide position 172, causing the aspartic acid (D) at amino acid position 58 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
