human agxt wild-type allele is located in the vicinity of 2q37.3 and is approximately 12 kb in length. this allele, which encodes alanine-glyoxylate aminotransferase protein, is involved in gluconeogenesis, l-serine metabolism and glyoxylate detoxification. mutations in the gene are associated with primary hyperoxaluria 1.GRHPR wt Allele|GLXR|GLYD|Glycerate-2-Dehydrogenase Gene|Glyoxylate and Hydroxypyruvate Reductase wt Allele|MSTP035|PH2|Primary Hyperoxaluria Type 2 Gene
human grhpr wild-type allele is located in the vicinity of 9p13.2 and is approximately 14 kb in length. this allele, which encodes glyoxylate reductase/hydroxypyruvate reductase protein, plays a role in hydroxypyruvate and glyoxylate metabolism. mutation of the gene is associated with type ii primary hyperoxaluria.Primary Hyperoxaluria
