Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 4P and 2B. PM1 PM2 BP4_Moderate

The NM_006494.4(ERF):c.1442A>G(p.Lys481Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K481E) has been classified as Uncertain significance.

• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 2.68

Genes affected

ERF (HGNC:3444): (ETS2 repressor factor) ETS2 is a transcription factor and protooncogene involved in development, apoptosis, and the regulation of telomerase. The protein encoded by this gene binds to the ETS2 promoter and is a strong repressor of ETS2 transcription. Several transcript variants encoding two different isoforms have been found for this gene.

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM1: In a cross_link Glycyl lysine isopeptide (Lys-Gly) (interchain with G-Cter in SUMO2) (size 0) in uniprot entity ERF_HUMAN
• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.23266283).
