Genes affected

EPC1 (HGNC:19876): (enhancer of polycomb homolog 1) This gene encodes a member of the polycomb group (PcG) family. The encoded protein is a component of the NuA4 histone acetyltransferase complex and can act as both a transcriptional activator and repressor. The encoded protein has been linked to apoptosis, DNA repair, skeletal muscle differentiation, gene silencing, and adult T-cell leukemia/lymphoma. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2012]

EPC1-AS2 (HGNC:56646): (EPC1 antisense RNA 2)

ACMG classification

Verdict is Benign. Variant got -11 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.27).
• BP7: Synonymous conserved (PhyloP=2.9 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.314 is higher than 0.05.
