Kidney cysts in patients with HOGA1 variants
Clinical Nephrology
|March 17, 2023
Summary
Genetic variants in HOGA1, an enzyme linked to primary hyperoxaluria type 3, may cause kidney cysts. This study explores how HOGA1 mutations lead to kidney stone formation and cyst development.
Area of Science:
- Nephrology
- Medical Genetics
- Biochemistry
Background:
- Genetic testing is increasingly accessible, aiding nephrologists in understanding disease mechanisms.
- Primary hyperoxaluria type 3 is associated with the HOGA1 gene and kidney stone formation.
Purpose of the Study:
- To describe the clinical and genetic findings of two patients with kidney cysts and HOGA1 variants.
- To explore potential mechanisms linking HOGA1 mutations to kidney cyst development.
Main Methods:
- Clinical case description.
- Genetic variant analysis in HOGA1.
- Pathophysiological mechanism exploration.
Main Results:
- Two patients with kidney cysts were identified with variants in the HOGA1 gene.
- HOGA1 is a mitochondrial enzyme linked to primary hyperoxaluria type 3 and oxalate kidney stones.
Conclusions:
- HOGA1 mutations may predispose individuals to crystal deposition, tubule dilation, and inflammasome activation.
- These processes potentially lead to kidney cyst formation in patients with HOGA1 variants.

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...
