FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the class-I pyridine nucleotide-disulfide oxidoreductase family. This enzyme is a homodimeric flavoprotein. It is a central enzyme of cellular antioxidant defense, and reduces oxidized glutathione disulfide (GSSG) to the sulfhydryl form GSH, which is an important cellular antioxidant. Rare mutations in this gene result in hereditary glutathione reductase deficiency. Multiple alternatively spliced transcript variants encoding different isoforms have been found.

PHENOTYPE: A homozygous mutation disrupting this gene between exon 1-2 results in a decreased retinal artery-to-vein ratio. Another small deletion of exons 2-5 has no phenotypic effect. Electrophoretic alleles designated a (C57BL/6, CE) vs. allele b (SJL, SWR) are known. [provided by MGI curators]
