This is a rare, but now well described entity secondary to either mutations in the AVPR2 gene that codes for the vasopressin antidiuretic (V2) receptor or to mutations in the AQP2 gene that codes for the vasopressin dependent water channel. (inserm.fr)
In the present case study, we identified two new mutations in the AQP-2 gene. (bvsalud.org)
Previous studies have shown that there is no hot spot for mutations in the AQP-2 gene, and thus genetic analysis for individual patients is helpful for genetic counseling and early diagnosis. (bvsalud.org)

Recessive1
It is also estimated that each human being is a carrier of around five recessive lethal genes and perhaps even more recessive disease genes, which may pose risk for the offspring of related individuals (such as cousin marriages). (dorak.info)
