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]

Dec 17, 2021

The c.202G>A (p.A68T) 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 202, causing the alanine (A) at amino acid position 68 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
