Case Report

F Choi, MT Leung, KL Ng, TKC Tsui


Abstract

Congenital nephrogenic diabetes insipidus is a rare disorder that affects the kidneys' ability in urine concentration. Both diagnosis and management of the disease, especially during infancy are challenging. We report a five-month-old boy with failure to thrive and hypernatraemic dehydration. The diagnosis of nephrogenic diabetes insipidus was confirmed with water deprivation test and mutation analysis of the aquaprorin-2 (AQP2) gene. Parental genetic analysis showed that the proband is a compound heterozygote for two pathogenic AQP2 variants.
