Gitelman综合征(Gitelman syndrome,GS)是一种常染色体隐性遗传所致的失盐失钾性肾小管性疾病,患者远端小管噻嗪类敏感性氯化钠协同转运蛋白(sodium-chloride cotransporter,NCC)的编码基因发生了突变,即SLC12A3双等位基因失活性^([1]),以低钾性碱中毒、低镁血症、低钙尿症和继发性醛固酮增多症为主要表现,临床表现多样,缺乏特异性^([2])。本文报道1例杂合致病GS合并库欣病的患者,与本例患者有同样致病性的杂合变异[SLC12A3 chr16:56914054 Exon12 NM-000339.3:c.1456G>A(p.Asp486Asn)]。
