Symptoms and Testing information for INVS Gene Nephronophthisis Type 2 Genetic Test

Nephronophthisis Type 2, caused by mutations in the INVS gene, is a rare genetic disorder that primarily affects the kidneys. This condition is part of a group of diseases known as ciliopathies, which are characterized by abnormalities in the function or structure of cellular cilia. Cilia are microscopic, hair-like structures on the surface of cells that play crucial roles in various biological processes. Nephronophthisis leads to chronic kidney disease, ultimately progressing to end-stage kidney disease. Recognizing the symptoms early on can be vital for managing the condition and improving the quality of life for those affected. DNA Labs UAE offers a comprehensive genetic test for Nephronophthisis Type 2, providing crucial information for affected individuals and their families.

Symptoms of Nephronophthisis Type 2

The symptoms of Nephronophthisis Type 2 typically begin in childhood, although they can vary widely in severity and onset. Early detection and diagnosis are crucial for managing the condition effectively. Key symptoms include:

  • Polyuria and Polydipsia: Excessive urination and thirst are common initial symptoms, resulting from the kidneys’ inability to concentrate urine.
  • Secondary Enuresis: Children who previously had no issues may start experiencing bedwetting due to the progression of the condition.
  • Progressive Renal Insufficiency: As the disease progresses, the kidneys’ ability to filter blood deteriorates, leading to waste accumulation in the body.
  • Anemia: A decrease in red blood cells can occur, leading to fatigue and weakness.
  • Bone Abnormalities: Skeletal symptoms such as bone pain and deformities may develop due to imbalances in calcium and phosphate.
  • Retinal Degeneration: Some individuals may experience vision problems due to the impact on the retina, although this is more common in other types of Nephronophthisis.

Importance of Genetic Testing

Genetic testing for Nephronophthisis Type 2 is crucial for confirming the diagnosis, especially in cases where the clinical symptoms are not definitive. The test offered by DNA Labs UAE specifically targets the INVS gene mutations responsible for the condition. Identifying the mutation can help in understanding the disease’s progression, potential complications, and can guide treatment options. Additionally, genetic testing is valuable for family planning and determining the risk of passing the condition on to future generations.

Cost of the Test

The cost of the INVS Gene Nephronophthisis Type 2 Genetic Test at DNA Labs UAE is 4400 AED. While the test represents a significant investment, the information it provides can be invaluable for affected individuals and their families. It offers insights into the condition that can lead to more personalized and effective management strategies, potentially improving outcomes and quality of life.


Nephronophthisis Type 2 is a challenging condition that requires early detection and comprehensive management to mitigate its impact on the kidneys and other organs. The symptoms can vary widely, making genetic testing an essential tool for accurate diagnosis and management.
