UMOD and you! Explaining a rare disease diagnosis

Area of Science:

• Nephrology
• Medical Genetics
• Rare Inherited Diseases

Background:

• Precise molecular genetic diagnosis of rare inherited diseases is often a lengthy process.
• Rare inherited kidney diseases present genetic heterogeneity and clinical diversity, complicating nomenclature.
• Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a significant inherited kidney disease, accounting for approximately 2% of cases leading to end-stage kidney disease.

Purpose of the Study:

• To review the current understanding of Autosomal dominant tubulointerstitial kidney disease (ADTKD).
• To provide patient-centered information for better conceptual understanding, recognition, diagnosis, and management of ADTKD.
• To highlight the role of modern molecular testing in diagnosing rare inherited kidney diseases.

Main Methods:

• Review of current literature and understanding of Autosomal dominant tubulointerstitial kidney disease (ADTKD).
• Analysis of genetic heterogeneity and clinical diversity in rare inherited kidney diseases.
• Focus on molecular testing strategies for improved diagnosis.

Main Results:

• Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a heterogeneous inherited kidney disorder.
• The *UMOD* gene is the most commonly implicated, with at least 6 known subtypes.
• Currently, no specific treatments exist for ADTKD.

Conclusions:

• Advances in molecular testing are improving the diagnosis of rare inherited kidney diseases.
• Enhanced understanding and patient-centered information are crucial for the recognition, diagnosis, and management of ADTKD.
• Further research is needed to develop specific treatments for ADTKD.
