Advances in renal genetic diagnosis

Area of Science:

• Genetics and Genomics
• Nephrology
• Medical Diagnostics

Background:

• Hereditary nephropathies are often clinically and genetically heterogeneous.
• Genetic diagnostics are integral to current best-practice guidelines for hereditary kidney diseases.
• Conventional genetic testing methods struggle with the increasing number of genes implicated in hereditary nephropathies.

Purpose of the Study:

• To highlight the benefits of next-generation sequencing (NGS) in diagnosing hereditary nephropathies.
• To emphasize the importance of genetic diagnostics for patient management and therapeutic decisions.
• To address the challenges in genetic data interpretation and the need for multidisciplinary collaboration.

Main Methods:

• Utilizing next-generation sequencing (NGS)-based approaches, including multi-gene panels, for parallel analysis of disease genes.
• Applying genetic diagnostics for improved clinical management and genetic counseling.
• Fostering a multidisciplinary approach integrating genetics and clinical expertise for data interpretation.

Main Results:

• NGS allows for cost-effective, parallel analysis of numerous genes in hereditary nephropathies.
• Knowledge of genotype aids in discussions regarding transplantation and therapeutic strategies.
• Accurate genetic diagnosis facilitates early detection of complications and reduces invasive procedures.

Conclusions:

• NGS-based genetic testing is a powerful tool for diagnosing hereditary nephropathies, overcoming limitations of conventional methods.
• Accurate genetic diagnosis is crucial for effective genetic counseling, recurrence risk assessment, and improved patient and family management.
• Interpreting complex genetic data requires a multidisciplinary setting, paving the way for digitized medicine benefits in nephrology.
