Bartter syndrome gene panel

Bartter Syndrome Gene Panel

Overview

The Bartter Syndrome Gene Panel is a specialized genetic test used to identify mutations associated with Bartter syndrome, a group of rare inherited kidney disorders characterized by salt wasting, electrolyte imbalances, and metabolic alkalosis. This panel analyzes multiple genes known to be linked to different types of Bartter syndrome, helping clinicians establish an accurate diagnosis and guide patient management.

Genes Commonly Included

The panel may include analysis of genes such as:

• SLC12A1
• KCNJ1
• CLCNKB
• BSND
• CLCNKA
• MAGED2
• Other clinically relevant genes associated with renal tubular disorders

When is the Test Recommended?

• Persistent low potassium levels (hypokalemia)
• Metabolic alkalosis
• Excessive urination (polyuria)
• Excessive thirst (polydipsia)
• Growth retardation or failure to thrive
• Family history of Bartter syndrome or related kidney disorders
• Prenatal suspicion of Bartter syndrome due to polyhydramnios

Test Method

• Next-Generation Sequencing (NGS)
• Deletion/Duplication analysis (if applicable)

Sample Required

• Peripheral blood (EDTA) or as specified by the laboratory

Benefits of Testing

• Confirms the genetic cause of Bartter syndrome
• Differentiates between various subtypes
• Assists in treatment planning and prognosis
• Supports family screening and genetic counseling
• Helps assess recurrence risk in future pregnancies

Clinical Significance

Early genetic diagnosis enables timely intervention, appropriate electrolyte management, and long-term monitoring, improving patient outcomes and quality of life.

Turnaround Time

Typically 2–4 weeks, depending on the laboratory methodology and scope of analysis.
