Genes affected

DNAJB1 (HGNC:5270): (DnaJ heat shock protein family (Hsp40) member B1) This gene encodes a member of the DnaJ or Hsp40 (heat shock protein 40 kD) family of proteins. DNAJ family members are characterized by a highly conserved amino acid stretch called the 'J-domain' and function as one of the two major classes of molecular chaperones involved in a wide range of cellular events, such as protein folding and oligomeric protein complex assembly. The encoded protein is a molecular chaperone that stimulates the ATPase activity of Hsp70 heat-shock proteins in order to promote protein folding and prevent misfolded protein aggregation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

The c.29G>A (p.G10D) alteration is located in exon 1 (coding exon 1) of the DNAJB1 gene. This alteration results from a G to A substitution at nucleotide position 29, causing the glycine (G) at amino acid position 10 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
