Test ID RBART Bartter Syndrome Gene Panel, Varies

Ordering Guidance

The genes associated with Gitelman syndrome (SLC12A3) and autosomal dominant familial hypocalciuric hypercalcemia (FHH) (CASR) are not included on this panel. If testing for these disorders and Bartter syndrome on a single panel is desired, order RSCGP / Nephrocalcinosis, Nephrolithiasis, and Renal Electrolyte Imbalance Gene Panel, Varies. It is inappropriate to order both this test and RSCGP on the same patient because the genes on this panel are included on the RSCGP panel.


Targeted testing for familial variants (also called site-specific or known mutations testing) is available for the genes on this panel. See FMTT / Familial Mutation, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.


Customization of this panel and single gene analysis for any gene present on this panel are available. For more information, see CGPH / Custom Gene Panel, Hereditary, Next-Generation Sequencing, Varies.
