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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2024The c.1319A>G (p.D440G) alteration is located in exon 11 (coding exon 11) of the HSP90B1 gene. This alteration results from a A to G substitution at nucleotide position 1319, causing the aspartic acid (D) at amino acid position 440 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
