Genes affected

HSF2BP (HGNC:5226): (heat shock transcription factor 2 binding protein) HSF2 binding protein (HSF2BP) associates with HSF2. The interaction occurs between the trimerization domain of HSF2 and the amino terminal hydrophilic region of HSF2BP that comprises two leucine zipper motifs. HSF2BP may therefore be involved in modulating HSF2 activation. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.440G>A (p.G147E) alteration is located in exon 5 (coding exon 4) of the HSF2BP gene. This alteration results from a G to A substitution at nucleotide position 440, causing the glycine (G) at amino acid position 147 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
