Genes affected

MGST2 (HGNC:7063): (microsomal glutathione S-transferase 2) The MAPEG (Membrane Associated Proteins in Eicosanoid and Glutathione metabolism) family consists of six human proteins, several of which are involved in the production of leukotrienes and prostaglandin E, important mediators of inflammation. This gene encodes a protein which catalyzes the conjugation of leukotriene A4 and reduced glutathione to produce leukotriene C4. Alternatively spliced transcript variants encoding different isoforms have been identified in this gene. [provided by RefSeq, Feb 2011]

ACMG classification

Our verdict: Benign. The variant received -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.39).
• BP6: Variant 4-139695263-C-T is Benign according to our data. Variant chr4-139695263-C-T is described in ClinVar as Benign. ClinVar VariationId is 710321.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.257 with no splicing effect.
• BS2: High Homozygotes in GnomAd4 at 2 AR gene
