Genes affected

HSF4 (HGNC:5227): (heat shock transcription factor 4) Heat-shock transcription factors (HSFs) activate heat-shock response genes under conditions of heat or other stresses. HSF4 lacks the carboxyl-terminal hydrophobic repeat which is shared among all vertebrate HSFs and has been suggested to be involved in the negative regulation of DNA binding activity. Two alternatively spliced transcripts encoding distinct isoforms and possessing different transcriptional activity have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -17 ACMG points.

• BP4: Computational evidence support a benign effect (REVEL=0.012).
• BP6: Variant 16-67169782-C-A is Benign according to our data. Variant chr16-67169782-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 320191.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-1.86 with no splicing effect.
• BS1: Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000282 (43/152298) while in subpopulation AMR AF = 0.00118 (18/15306). AF 95% confidence interval is 0.00076. There are 1 homozygotes in GnomAd4. There are 25 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
