Genes affected
HSPA13 (HGNC:11375): (heat shock protein family A (Hsp70) member 13) The protein encoded by this gene is a member of the heat shock protein 70 family and is found associated with microsomes. Members of this protein family play a role in the processing of cytosolic and secretory proteins, as well as in the removal of denatured or incorrectly-folded proteins. The encoded protein contains an ATPase domain and has been shown to associate with a ubiquitin-like protein. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 08, 2022The c.325G>A (p.A109T) alteration is located in exon 2 (coding exon 2) of the HSPA13 gene. This alteration results from a G to A substitution at nucleotide position 325, causing the alanine (A) at amino acid position 109 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
