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]

The c.1225T>G (p.L409V) alteration is located in exon 7 (coding exon 6) of the HSP90AA1 gene. This alteration results from a T to G substitution at nucleotide position 1225, causing the leucine (L) at amino acid position 409 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
