Genes affected

HSP90AB1 (HGNC:5258): (heat shock protein 90 alpha family class B member 1) This gene encodes a member of the heat shock protein 90 family; these proteins are involved in signal transduction, protein folding and degradation and morphological evolution. This gene encodes the constitutive form of the cytosolic 90 kDa heat-shock protein and is thought to play a role in gastric apoptosis and inflammation. Alternative splicing results in multiple transcript variants. Pseudogenes have been identified on multiple chromosomes. [provided by RefSeq, Dec 2012]

Aug 31, 2022

The c.1390G>A (p.D464N) alteration is located in exon 9 (coding exon 8) of the HSP90AB1 gene. This alteration results from a G to A substitution at nucleotide position 1390, causing the aspartic acid (D) at amino acid position 464 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
