Genes affected

DNAJB6 (HGNC:14888): (DnaJ heat shock protein family (Hsp40) member B6) This gene encodes a member of the DNAJ protein family. 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. This family member may also play a role in polyglutamine aggregation in specific neurons. Alternative splicing of this gene results in multiple transcript variants; however, not all variants have been fully described. [provided by RefSeq, Jul 2008]

The c.938G>A (p.R313K) alteration is located in exon 10 (coding exon 9) of the DNAJB6 gene. This alteration results from a G to A substitution at nucleotide position 938, causing the arginine (R) at amino acid position 313 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
