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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.1453T>C (p.Y485H) alteration is located in exon 9 (coding exon 8) of the HSP90AB1 gene. This alteration results from a T to C substitution at nucleotide position 1453, causing the tyrosine (Y) at amino acid position 485 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
