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]

Ambry Genetics

Nov 12, 2021

The c.740A>G (p.K247R) alteration is located in exon 5 (coding exon 4) of the HSP90AA1 gene. This alteration results from a A to G substitution at nucleotide position 740, causing the lysine (K) at amino acid position 247 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
