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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2022The c.609G>C (p.L203F) alteration is located in exon 7 (coding exon 6) of the HSF2BP gene. This alteration results from a G to C substitution at nucleotide position 609, causing the leucine (L) at amino acid position 203 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
