Variant summary

Our verdict is Pathogenic. The variant received 18 ACMG points: 18P and 0B. PM1 PM2 PM5 PP3_Strong PP5_Very_Strong

The NM_000399.5(EGR2):​c.1075C>T​(p.Arg359Trp) 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 pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R359G) has been classified as Likely pathogenic.

Genes affected

EGR2 (HGNC:3239): (early growth response 2) The protein encoded by this gene is a transcription factor with three tandem C2H2-type zinc fingers. Defects in this gene are associated with Charcot-Marie-Tooth disease type 1D (CMT1D), Charcot-Marie-Tooth disease type 4E (CMT4E), and with Dejerine-Sottas syndrome (DSS). Multiple transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

ACMG classification

Our verdict: Pathogenic. The variant received 18 ACMG points.

• PM1: In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 9 uncertain in NM_000399.5
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr10-62813563-G-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 1422578.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.94
• PP5: Variant 10-62813563-G-A is Pathogenic according to our data. Variant chr10-62813563-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 16752.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
