Variant summary

Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1 PM2 PM5 PP3_Moderate

The NM_006494.4(ERF):c.194G>T(p.Arg65Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,214 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R65Q) has been classified as Likely pathogenic.

• Frequency: Genomes: 𝑓 0.0000066 (0 hom., cov: 32)
• Consequence: ERF NM_006494.4 missense
• Clinical Significance: Not reported in ClinVar

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 Likely_pathogenic. Variant got 8 ACMG points.

• PM1: In a DNA_binding_region ETS (size 80) in uniprot entity ERF_HUMAN there are 8 pathogenic changes around while only 0 benign (100%) in NM_006494.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr19-42250394-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 55926.We mark this variant Likely_pathogenic, oryginal submissions are: {Uncertain_significance=2, Likely_pathogenic=1}.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.915
