Genes affected

HSP90B1 (HGNC:12028): (heat shock protein 90 beta family member 1) This gene encodes a member of a family of adenosine triphosphate(ATP)-metabolizing molecular chaperones with roles in stabilizing and folding other proteins. The encoded protein is localized to melanosomes and the endoplasmic reticulum. Expression of this protein is associated with a variety of pathogenic states, including tumor formation. There is a microRNA gene located within the 5' exon of this gene. There are pseudogenes for this gene on chromosomes 1 and 15. [provided by RefSeq, Aug 2012]

The c.727C>T (p.R243W) alteration is located in exon 5 (coding exon 5) of the HSP90B1 gene. This alteration results from a C to T substitution at nucleotide position 727, causing the arginine (R) at amino acid position 243 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
