When AGT activity is reduced or absent, glyoxylate is converted to oxalate, which cannot be metabolized and must be excreted by the kidneys. Insoluble calcium oxalate crystals form due to high urinary oxalate concentration. Urinary crystals aggregate, leading to nephrolithiasis (i.e., calcium oxalate kidney stones) in the renal pelvis / urinary tract; often the crystals deposit in kidney parenchyma (nephrocalcinosis). The age at presentation of PH1 ranges from infancy (age &lt;12 months) in 10% of individuals, childhood/adolescence (age 1-17 years) in 70%, and adulthood (age =18 years) in 20%. The natural history of untreated PH1 is (1) progressive decline in kidney function due to complications of nephrolithiasis (e.g., urinary obstruction, infection) and nephrocalcinosis, and (2) in persons with advanced chronic kidney disease (CKD), high plasma oxalate concentrations result in other organ and tissue damage from calcium oxalate deposition (i.e., &quot;oxalosis&quot;), most commonly in the bones, heart, and retina. In the absence of treatment, progression of oxalosis results in death from kidney failure and/or other organ involvement." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln"><div class="excerpt">Excerpted from the <i>GeneReview: </i><a href="/books/NBK1283" target="_blank">Primary Hyperoxaluria Type 1</a></div><div>Primary hyperoxaluria type 1 (PH1) is caused by deficiency of the liver peroxisomal enzyme alanine-glyoxylate aminotransferase (AGT), which catalyzes the conversion of glyoxylate to glycine. When AGT activity is reduced or absent, glyoxylate is converted to oxalate, which cannot be metabolized and must be excreted by the kidneys. Insoluble calcium oxalate crystals form due to high urinary oxalate concentration. Urinary crystals aggregate, leading to nephrolithiasis (i.e., calcium oxalate kidney stones) in the renal pelvis / urinary tract; often the crystals deposit in kidney parenchyma (nephrocalcinosis). The age at presentation of PH1 ranges from infancy (age &lt;12 months) in 10% of individuals, childhood/adolescence (age 1-17 years) in 70%, and adulthood (age ≥18 years) in 20%. The natural history of untreated PH1 is (1) progressive decline in kidney function due to complications of nephrolithiasis (e.g., urinary obstruction, infection) and nephrocalcinosis, and (2) in persons with advanced chronic kidney disease (CKD), high plasma oxalate concentrations result in other organ and tissue damage from calcium oxalate deposition (i.e., "oxalosis"), most commonly in the bones, heart, and retina. In the absence of treatment, progression of oxalosis results in death from kidney failure and/or other organ involvement. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1283#ph1.Summary" target="NBK1283">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Diagnosis" target="NBK1283">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Clinical_Characteristics" target="NBK1283">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Genetically_Related_Allelic_Disorder" target="NBK1283">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Differential_Diagnosis" target="NBK1283">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Management" target="NBK1283">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Genetic_Counseling" target="NBK1283">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Resources" target="NBK1283">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Molecular_Genetics" target="NBK1283">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.Chapter_Notes" target="NBK1283">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1283#ph1.References" target="NBK1283">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Primary hyperoxaluria type I is an autosomal recessive disorder characterized by an accumulation of calcium oxalate in various bodily tissues, especially the kidney, resulting in renal failure. Affected individuals have decreased or absent AGXT activity and a failure to transaminate glyoxylate, which causes the accumulated glyoxylate to be oxidized to oxalate. This overproduction of oxalate results in the accumulation of nonsoluble calcium oxalate in various body tissues, with pathologic sequelae (Takada et al., 1990; Danpure et al., 1989; Williams et al., 2009)&#13;
Genetic Heterogeneity of Primary Hyperoxaluria&#13;
Type II primary hyperoxaluria (HP2; 260000) is caused by mutation in the glyoxylate reductase/hydroxypyruvate reductase gene (GRHPR; 604296) on chromosome 9. Type III primary hyperoxaluria (HP3; 613616) is caused by mutation in the mitochondrial dihydrodipicolinate synthase-like gene (DHDPSL; 613597) on chromosome 10q24.  <a target="_blank" href="http://www.omim.org/entry/259900">http://www.omim.org/entry/259900</a></div><div class="mgSection"><strong>From MedlinePlus Genetics</strong><br />Primary hyperoxaluria is a rare condition characterized by recurrent kidney and bladder stones. The condition often results in end stage renal disease (ESRD), which is a life-threatening condition that prevents the kidneys from filtering fluids and waste products from the body effectively.<br /><br />Primary hyperoxaluria results from the overproduction of a substance called oxalate. Oxalate is filtered through the kidneys and excreted as a waste product in urine, leading to abnormally high levels of this substance in urine (hyperoxaluria). During its excretion, oxalate can combine with calcium to form calcium oxalate, a hard compound that is the main component of kidney and bladder stones. Deposits of calcium oxalate can damage the kidneys and other organs and lead to blood in the urine (hematuria), urinary tract infections, kidney damage, ESRD, and injury to other organs. Over time, kidney function decreases such that the kidneys can no longer excrete as much oxalate as they receive. As a result oxalate levels in the blood rise, and the substance gets deposited in tissues throughout the body (systemic oxalosis), particularly in bones and the walls of blood vessels. Oxalosis in bones can cause fractures.<br /><br />There are three types of primary hyperoxaluria that differ in their severity and genetic cause. In primary hyperoxaluria type 1, kidney stones typically begin to appear anytime from childhood to early adulthood, and ESRD can develop at any age. Primary hyperoxaluria type 2 is similar to type 1, but ESRD develops later in life. In primary hyperoxaluria type 3, affected individuals often develop kidney stones in early childhood, but few cases of this type have been described so additional signs and symptoms of this type are unclear.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/primary-hyperoxaluria">https://medlineplus.gov/genetics/condition/primary-hyperoxaluria</a></div></div>

Deposits of calcium oxalate can damage the kidneys and other organs and lead to blood in the urine (hematuria), urinary tract infections, kidney damage, ESRD, and injury to other organs. Over time, kidney function decreases such that the kidneys can no longer excrete as much oxalate as they receive. As a result oxalate levels in the blood rise, and the substance gets deposited in tissues throughout the body (systemic oxalosis), particularly in bones and the walls of blood vessels. Oxalosis in bones can cause fractures.\n\nThere are three types of primary hyperoxaluria that differ in their severity and genetic cause. In primary hyperoxaluria type 1, kidney stones typically begin to appear anytime from childhood to early adulthood, and ESRD can develop at any age. Primary hyperoxaluria type 2 is similar to type 1, but ESRD develops later in life. In primary hyperoxaluria type 3, affected individuals often develop kidney stones in early childhood, but few cases of this type have been described so additional signs and symptoms of this type are unclear.</div>

<div class="spaceAbove">Kleta (2006) reviewed aspects of renal stone disease. Nephrolithiasis and urolithiasis remain major public health problems of largely unknown cause. While disorders such as cystinuria (220100) and primary hyperoxaluria (see 259900) that have nephrolithiasis as a major feature have advanced understanding of the metabolic and physiologic processes of stone formation in general, they have not addressed the etiology of calcium oxalate stone formation, responsible for approximately 75% of urolithiasis cases in humans. Men are affected twice as often as women, but children show no such gender bias. The recurrence rate is also high. In populations of European ancestry, 5 to 10% of adults experience the painful precipitation of calcium oxalate in their urinary tracts.&#13; Thorleifsson et al. (2009) noted that between 35 and 65% of hypercalciuric stone formers and up to 70% of subjects with hypercalciuria have relatives with nephrolithiasis, and twin studies have estimated the heritability of kidney stones to be 56%.&#13; Genetic Heterogeneity of Calcium Oxalate Nephrolithiasis&#13; See also CAON2 (620374), caused by mutation in the OXGR1 gene (606922) on chromosome 13q32.</div>
