Genes affected

DNAJC28 (HGNC:1297): (DnaJ heat shock protein family (Hsp40) member C28) This gene encodes a member of the DnaJ heat shock protein family. The encoded protein, which contains a conserved N-terminal DnaJ domain, is thought to play a role in protein folding or act as a molecular chaperone protein. [provided by RefSeq, Oct 2016]

The c.604C>T (p.R202C) alteration is located in exon 2 (coding exon 1) of the DNAJC28 gene. This alteration results from a C to T substitution at nucleotide position 604, causing the arginine (R) at amino acid position 202 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
