* To whom correspondence should be addressed. Gitelman syndrome is caused by mutations of the SLC12A3 gene, which encodes the thiazide-sensitive NaCl transporter NCCT. Although several mutations causing Gitelman syndrome have been described, their molecular consequences have been rarely studied. We report a patient with Gitelman syndrome due to a mutation in the GT donor splicing site of intron 9. The analysis of RNA from peripheral blood cells showed a complete deletion of exon 9. This case report confirms the feasibility of using readily accessible blood cells to study the expression of the SLC12A3 gene, a procedure that may facilitate further studies of the functional genomics of Gitelman syndrome.
