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]
UQCC6 (HGNC:34450): (ubiquinol-cytochrome c reductase complex assembly factor 6) Involved in mitochondrial respiratory chain complex III assembly. Located in mitochondrial inner membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2021The c.1397G>A (p.R466H) alteration is located in exon 12 (coding exon 12) of the HSP90B1 gene. This alteration results from a G to A substitution at nucleotide position 1397, causing the arginine (R) at amino acid position 466 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
