Definition
Bartter syndrome is a rare inherited disease charachterized by thickness of the ascending limb of the loop of Henle which results in salt wasting, low potassium and metabolic alkalosis. Mutations of several genes encoding the transporters involved in salt reabsortion cause different types of BS. The majority are autosmal recessive, but there are also autosomal dominant forms.
Why to perform genetic testing in cases with suspected BS?
- To confirm the diagnosis
- To better perform risk stratification and prognosis
- To identify other relatives at risk to develop the disease
- To enable the possibility of eventual future gene therapy
Our BS panel
BSND, CASR, CLCNKA, CLCNKB, KCNJ1, SLC12A1
Important: All our panels can be modified based on the phenotype. Please contact us if you have questions
What to expect from this test: The yield of the genetic test in clear phenotyped cases is close to 80%
