Familial central or neurohypophyseal diabetes insipidus (FNDI) results from insufficient production of antidiuretic hormone arginine vasopressin, which is caused by mutations in arginine vasopressin-neurophysin II gene (AVP-NPII). In this study, we present the clinical features of a male Turkish patient with autosomal dominant neurohypophyseal DI caused by a novel mutation (p.E108D). The prospective clinical data were collected for the proband patient and his family members. T...

Diabetes insipidus (DI) is a disorder which is rarely seen and it is characterized by polydipsia and polyuria. Inadequate secretion of arginine vasopressin (AVP) from hypothalamus or inadequate response of kidney cells to AVP could be causes of DI. Therefore, any mutations in AVPR2, AVP and AQP2 genes which are the parts of that stimulation and response pathyway can cause DI. In this study, mutational analyse was performed for A45T mutation in AQP2 gene. We present a novel hom...
