Familial neurohypophyseal diabetes insipidus (FNDI) in humans is an autosomal dominant disorder caused by a variety of mutations in the arginine vasopressin (AVP) precursor. A new report demonstrates how heterozygosity for an AVP mutation causes FNDI (see the related article beginning on page 1697). Using an AVP knock-in mutation in mice, the study shows that FNDI is caused by retention of AVP precursors and progressive loss of AVP-producing neurons.
人类家族性神经垂体性尿崩症(FNDI)是一种常染色体显性疾病,由精氨酸加压素(AVP)前体中的多种突变引起。一项新报告展示了AVP突变的杂合性如何导致FNDI(见第1697页开始的相关文章)。该研究利用小鼠中的AVP基因敲入突变,表明FNDI是由AVP前体的潴留和分泌AVP的神经元的渐进性丧失所引起的。
