Genes affected

DNAJB4 (HGNC:14886): (DnaJ heat shock protein family (Hsp40) member B4) The protein encoded by this gene is a molecular chaperone, tumor suppressor, and member of the heat shock protein-40 family. The encoded protein binds the cell adhesion protein E-cadherin and targets it to the plasma membrane. This protein also binds incorrectly folded E-cadherin and targets it for endoplasmic reticulum-associated degradation. This gene is a strong tumor suppressor for colorectal carcinoma, and downregulation of it may serve as a good biomarker for predicting patient outcomes. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2015]

The c.862G>A (p.G288R) alteration is located in exon 3 (coding exon 3) of the DNAJB4 gene. This alteration results from a G to A substitution at nucleotide position 862, causing the glycine (G) at amino acid position 288 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
