Genes affected
HSP90AA1 (HGNC:5253): (heat shock protein 90 alpha family class A member 1) The protein encoded by this gene is an inducible molecular chaperone that functions as a homodimer. The encoded protein aids in the proper folding of specific target proteins by use of an ATPase activity that is modulated by co-chaperones. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2023The c.688G>A (p.V230I) alteration is located in exon 5 (coding exon 4) of the HSP90AA1 gene. This alteration results from a G to A substitution at nucleotide position 688, causing the valine (V) at amino acid position 230 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
