Summary
Genomic testing is crucial for diagnosing cystic kidney diseases like Autosomal Dominant Polycystic Kidney Disease (ADPKD), especially when imaging is inconclusive. Genetic diagnosis guides treatment, family screening, and reproductive choices.
Area of Science:
- Nephrology
- Genetics
- Precision Medicine
Background:
- Diagnosis of Autosomal Dominant Polycystic Kidney Disease (ADPKD) traditionally relies on clinical and imaging criteria (ultrasound, MRI).
- Clinical diagnosis has limitations, particularly in atypical cases, young patients, or those without a family history.
- Genomic investigation is increasingly vital for cystic kidney disease management, aligning with precision medicine in Nephrology.
Purpose of the Study:
- To offer a practical guide for nephrologists on when to recommend genetic testing for cystic kidney diseases.
- To outline the technical and genetic counseling aspects of patient-centered genetic investigations.
- To highlight the importance of diagnostic genomics in ADPKD care, as emphasized by KDIGO guidelines.
Main Methods:
- This is a narrative review.
- It synthesizes current knowledge on the role of genomics in cystic kidney diseases.
- It focuses on practical considerations for nephrologists.
Main Results:
- Genetic diagnosis offers benefits beyond traditional methods, including family screening, reproductive decision support, and living donor selection.
- Accurate genotyping is essential for emerging genotype-specific therapies.
- Confirmed genetic diagnosis aids in utilizing genotype-specific prognostication tools.
Conclusions:
- Genetic testing is becoming a cornerstone in managing cystic kidney diseases, particularly ADPKD.
- It enhances diagnostic accuracy, informs clinical management, and supports personalized treatment strategies.
- Integrating genetic testing requires understanding technical aspects and genetic counseling needs for patient-centered care.

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

179
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

536
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...
