Gitelman syndrome caused by a novel hemiallelic missense mutation in SLC12A3 revealed by 16q12.2q21 microdeletion.

ABSTRACT: Gitelman syndrome (GS) is caused by biallelic mutations in SLC12A3 as an autosomal recessive trait. A patient with a de novo 16q12.2q21 microdeletion showed clinical features of GS. SLC12A3 included in the deletion was analyzed, and a rare missense variant (c.1222A>C [p.N406H]) was identified as hemizygous. Consequently, GS was caused by the revealed SLC12A3 variant owing to chromosomal microdeletion.
