CatPrimary Hyperoxaluria Type Ii (Oxalosis Ii) (PH2)
Primary Hyperoxaluria Type II (PH2) in cats is a rare genetic disorder causing excessive oxalate buildup, leading to kidney stones and renal failure. Early DNA testing for PH2 helps identify affected cats, enabling timely intervention and better management. This hereditary condition results from mutations in the GRHPR gene, crucial for oxalate metabolism. Breeders and veterinarians rely on DNA tests to prevent passing PH2 to future generations. Accurate diagnosis through genetic screening improves treatment outcomes and quality of life for cats. If you suspect PH2 symptoms like urinary issues or lethargy, consult your vet for DNA testing. Prioritizing genetic health ensures your cat’s long-term wellness and vitality.

Test summary:
Primary Hyperoxaluria Type II (PH2) in cats is a rare genetic disorder causing excessive oxalate production. This leads to the formation of calcium oxalate crystals, which can accumulate in the kidneys and urinary tract. A DNA test can identify mutations responsible for PH2, enabling early diagnosis. Early detection helps manage symptoms and prevent severe kidney damage. Genetic testing is crucial for breeders to reduce the risk of passing PH2 to offspring.

Introduction to Primary Hyperoxaluria Type II (PH2)
Primary Hyperoxaluria Type II (PH2), also known as Oxalosis II, is a rare genetic disorder that affects the metabolism of oxalate in the body. This condition is caused by a deficiency of the enzyme glycolate oxidase, which is responsible for the conversion of glycolate into oxalate. When this enzyme is deficient, glycolate accumulates and is subsequently converted into oxalate in excess, leading to hyperoxaluria or elevated levels of oxalate in the urine.
Clinical Signs and Symptoms
In cats, PH2 can present with a variety of clinical signs that can significantly affect their quality of life. Common symptoms include the formation of calcium oxalate crystals or stones in the urinary tract, which can lead to urinary obstruction and painful urination. Other signs may include increased thirst and urination, vomiting, and, in severe cases, kidney damage or failure due to the accumulation of oxalate in the kidneys.
Diagnosis of Primary Hyperoxaluria Type II
The diagnosis of PH2 is typically made through a combination of clinical signs, urine analysis, and genetic testing. Urine tests often reveal elevated levels of oxalate, which can be a strong indicator of the condition. However, the definitive diagnosis is usually confirmed through DNA testing that identifies mutations in the relevant genes associated with PH2.
Management and Treatment
Management of Primary Hyperoxaluria Type II in cats primarily focuses on reducing the levels of oxalate in the body and alleviating symptoms. This may include dietary modifications to limit oxalate intake, increased hydration to help dilute urine, and medications to manage pain or inflammation. In cases of severe kidney damage or recurrent urinary obstruction, surgical intervention may be necessary.
Conclusion
Primary Hyperoxaluria Type II is a serious genetic condition that can have significant health implications for affected cats. Early diagnosis and management are critical in improving outcomes and quality of life for these animals. Genetic testing plays an essential role in confirming the diagnosis, allowing for timely intervention and care tailored to the specific needs of the cat.
