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

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.110964).

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000376 (55/1461254) while in subpopulation NFE AF= 0.0000441 (49/1111932). AF 95% confidence interval is 0.0000337. There are 0 homozygotes in gnomad4_exome. There are 24 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.1372C>G (p.R458G) alteration is located in exon 4 (coding exon 4) of the ERF gene. This alteration results from a C to G substitution at nucleotide position 1372, causing the arginine (R) at amino acid position 458 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with ERF-related conditions. This variant is present in population databases (rs766642440, ExAC 0.01%). This sequence change replaces arginine with glycine at codon 458 of the ERF protein (p.Arg458Gly). The arginine residue is moderately conserved and there is a moderate physicochemical difference between arginine and glycine. -
