Genes affected

SUZ12 (HGNC:17101): (SUZ12 polycomb repressive complex 2 subunit) This zinc finger gene has been identified at the breakpoints of a recurrent chromosomal translocation reported in endometrial stromal sarcoma. Recombination of these breakpoints results in the fusion of this gene and JAZF1. The protein encoded by this gene contains a zinc finger domain in the C terminus of the coding region.

ACMG classification

Our verdict: Benign. The variant received -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.53).
• BP6: Variant 17-31937507-C-T is Benign according to our data. Variant chr17-31937507-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 2647645.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=0.89 with no splicing effect.
• BS1: Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.00000936 (13/1388352) while in subpopulation EAS AF = 0.000338 (12/35534). AF 95% confidence interval is 0.000194. There are 0 homozygotes in GnomAdExome4. There are 6 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
• BS2: High AC in GnomAdExome4 at 13 AD gene.
