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]

NFE2L2 Gene-Disease associations (from GenCC):

• immunodeficiency, developmental delay, and hypohomocysteinemia

  Inheritance: AD Classification: STRONG, LIMITED Submitted by: Illumina, ClinGen, G2P, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.
