Genes affected
HSPA1B (HGNC:5233): (heat shock protein family A (Hsp70) member 1B) This intronless gene encodes a 70kDa heat shock protein which is a member of the heat shock protein 70 family. In conjuction with other heat shock proteins, this protein stabilizes existing proteins against aggregation and mediates the folding of newly translated proteins in the cytosol and in organelles. It is also involved in the ubiquitin-proteasome pathway through interaction with the AU-rich element RNA-binding protein 1. The gene is located in the major histocompatibility complex class III region, in a cluster with two closely related genes which encode similar proteins. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 13, 2023The c.193A>G (p.N65D) alteration is located in exon 1 (coding exon 1) of the HSPA1B gene. This alteration results from a A to G substitution at nucleotide position 193, causing the asparagine (N) at amino acid position 65 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
