Variant summary

Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PM2 PM5 PP5

The NM_006164.5(NFE2L2):​c.236A>T​(p.Glu79Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E79K) has been classified as Likely pathogenic.

• Frequency: Genomes: not found (cov: 33)
• Consequence: NFE2L2 NM_006164.5 missense
• Clinical Significance: Likely pathogenic no assertion criteria provided P:6
• Conservation: PhyloP100: 7.67

Genes affected

NFE2L2 (HGNC:7782): (NFE2 like bZIP transcription factor 2) This gene encodes a transcription factor which is a member of a small family of basic leucine zipper (bZIP) proteins. The encoded transcription factor regulates genes which contain antioxidant response elements (ARE) in their promoters; many of these genes encode proteins involved in response to injury and inflammation which includes the production of free radicals. Multiple transcript variants encoding different isoforms have been characterized for this gene. [provided by RefSeq, Sep 2015]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrnull-null-null-null is described in UniProt as null.
• PP5: Variant 2-177234081-T-A is Pathogenic according to our data. Variant chr2-177234081-T-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376467.Status of the report is no_assertion_criteria_provided, 0 stars.
