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]

The c.326G>A (p.R109Q) alteration is located in exon 5 (coding exon 5) of the MGST2 gene. This alteration results from a G to A substitution at nucleotide position 326, causing the arginine (R) at amino acid position 109 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
