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 GeneticsJan 03, 2022The c.244C>T (p.R82C) alteration is located in exon 3 (coding exon 2) of the HSP90AB1 gene. This alteration results from a C to T substitution at nucleotide position 244, causing the arginine (R) at amino acid position 82 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
